تاریخچه ویرایشهای

این صفحه تغییرات YouTube Data API (v3) و به‌روزرسانی‌های اسناد را فهرست می‌کند. در این تغییرات ثبت نام کنید .

13 مارس 2024

توجه: این یک اعلامیه منسوخ شدن است.

این به روز رسانی شامل تغییرات زیر است:

پارامتر sync برای روش‌های captions.insert و captions.update منسوخ شده است. YouTube از ۱۲ آوریل ۲۰۲۴ پشتیبانی از این پارامتر را متوقف خواهد کرد.

در نتیجه این تغییر، برنامه‌نویسان باید هنگام درج یا به‌روزرسانی تراک‌های شرح، اطلاعات زمان‌بندی را درج کنند وگرنه آپلود با شکست مواجه می‌شود.

12 مارس 2024

این به روز رسانی شامل تغییرات زیر است:

اسناد منبع captions به روز شده است تا توجه داشته باشید که حداکثر طول مجاز برای فیلد snippet.name 150 کاراکتر است. اگر نام آهنگ طولانی‌تر از آن باشد، API یک خطای nameTooLong را برمی‌گرداند.

7 مارس 2024

توجه: این یک اعلامیه منسوخ شدن است.

ویژگی منبع channel brandingSettings.channel.moderateComments منسوخ شده است. YouTube از ۷ مارس ۲۰۲۴ پشتیبانی از این پارامتر را متوقف خواهد کرد.

31 ژانویه 2024

این به روز رسانی شامل تغییرات زیر است:

پارامتر جدید forHandle روش channels.list شما را قادر می سازد تا اطلاعات یک کانال را با تعیین دسته YouTube آن بازیابی کنید.

9 نوامبر 2023

همه ارجاع‌ها به منبع videoId در زیر Comments حذف شده‌اند زیرا منبع videoId با استفاده از تماس API بازگردانده نمی‌شود.

12 سپتامبر 2023

توجه: این یک اعلامیه منسوخ شدن است.

روش comments.markAsSpam چندین سال است که منسوخ شده است. این روش قبلاً در YouTube پشتیبانی نمی‌شود و دیگر از طریق API پشتیبانی نمی‌شود.

یک اخطار منسوخ شدن به همه اسنادی که به روش comments.markAsSpam ارجاع می‌دهند اضافه شده است.

22 اوت 2023

اکنون روش search.list از پارامتر videoPaidProductPlacement پشتیبانی می کند. این پارامتر به شما امکان می‌دهد نتایج جستجو را فیلتر کنید تا فقط ویدیوهایی را که سازنده آن‌ها را دارای تبلیغات پولی معرفی کرده است، شامل شود.

18 آگوست 2023

تعریف liveStreamingDetails.concurrentViewers منبع video به‌روزرسانی شده است تا توجه داشته باشد که بیننده همزمان حساب می‌کند که YouTube Data API برمی‌گرداند ممکن است با تعداد بینندگان همزمان پردازش‌شده و ناخواسته موجود در YouTube Analytics متفاوت باشد. مرکز راهنمایی YouTube اطلاعات بیشتری درباره معیارهای پخش زنده ارائه می دهد.

7 آگوست 2023

همانطور که در 12 ژوئن 2023 اعلام شد ، پارامتر relatedToVideoId روش search.list منسوخ شده است. آن پارامتر دیگر پشتیبانی نمی شود و ارجاعات به پارامتر از اسناد API حذف شده است.

28 ژوئن 2023

روش thumbnails.set اکنون از خطای uploadRateLimitExceeded پشتیبانی می‌کند، که نشان می‌دهد کانال در 24 ساعت گذشته تصاویر کوچک زیادی را آپلود کرده است و باید بعداً دوباره امتحان کنید.

12 ژوئن 2023

توجه: این یک اعلامیه منسوخ شدن است.

پارامتر relatedToVideoId روش search.list منسوخ شده است. YouTube از ۷ اوت ۲۰۲۳ پشتیبانی از این پارامتر را متوقف خواهد کرد.

در حال حاضر، یک اخطار منسوخ شدن به مستندات روش search.list اضافه شده است. این پارامتر در تاریخ 7 اوت 2023 یا پس از آن به طور کامل از اسناد search.list حذف خواهد شد.

علاوه بر این، نمونه‌ای که نحوه بازیابی ویدیوهای مرتبط را نشان می‌دهد از راهنمای اجرای API حذف شده است.

22 اوت 2022

یادداشت‌های نوع تصحیح شده برای فیلدهای video.statistics به رشته‌هایی از طولانی بدون امضا.

5 آگوست 2022

YouTube نحوه تولید شناسه‌های شرح را تغییر داده است و به عنوان بخشی از این تغییر، شناسه‌های زیرنویس جدید را به همه آهنگ‌های زیرنویس اختصاص می‌دهد. این تغییر ممکن است برای برنامه‌هایی که مقادیر caption_id را ذخیره می‌کنند یک تغییر ناسازگار با عقب باشد، اگرچه روی برنامه‌هایی که مقادیر caption_id را ذخیره نمی‌کنند تأثیری نخواهد داشت.

از هم‌اکنون تا اول دسامبر 2022، روش‌های captions.list ، captions.update ، captions.download و و captions.delete از شناسه‌های تراک شرح قدیمی و جدید پشتیبانی می‌کنند. با این حال، در تاریخ 1 دسامبر 2022 یا پس از آن، YouTube از شناسه‌های تراک شرح قدیمی پشتیبانی نخواهد کرد. در آن زمان، فراخوانی هر یک از آن متدهای API با شناسه تراک عنوان قدیمی منجر به خطای captionNotFound می‌شود.

برای آماده شدن برای این تغییر، باید برنامه‌ریزی کنید که همه داده‌های ذخیره شده آهنگ زیرنویس را از هم‌اکنون تا 1 دسامبر 2022 جایگزین کنید. این بدان معناست که برای هر ویدیویی که داده‌های آهنگ شرح را برای آن ذخیره می‌کنید، باید داده‌های ذخیره‌شده فعلی را حذف کنید، سپس با روش captions.list برای بازیابی مجموعه فعلی از آهنگ‌های زیرنویس برای ویدیو و ذخیره داده‌ها در پاسخ API همانطور که معمولاً انجام می‌دهید.

12 جولای 2022

شرایط خدمات YouTube API Services به روز شده است. لطفاً برای اطلاعات بیشتر به شرایط خدمات YouTube API Services - Revision History مراجعه کنید.

27 آوریل 2022

توضیحات روش videos.insert به‌روزرسانی شده است تا توجه داشته باشید که حداکثر اندازه فایل برای ویدیوهای آپلود شده از 128 گیگابایت به 256 گیگابایت افزایش یافته است.

8 آوریل 2022

تعاریف پارامتر myRecentSubscribers و mySubscribers روش subscriptions.list هر دو به‌روزرسانی شده‌اند تا توجه داشته باشیم که حداکثر تعداد مشترکینی که توسط API بازگردانده می‌شوند ممکن است محدود باشد. این تغییر نشان دهنده یک تصحیح مستندات است و نه تغییر در رفتار API.

15 دسامبر 2021

همانطور که در 18 نوامبر 2021 اعلام شد، همراه با تغییراتی برای خصوصی کردن تعداد عدم پسندیدن ویدیو در کل پلتفرم YouTube ، ویژگی statistics.dislikeCount منبع video اکنون خصوصی است.

می‌توانید در وبلاگ رسمی YouTube درباره این تغییر اطلاعات بیشتری کسب کنید.

18 نوامبر 2021

در ارتباط با تغییراتی که برای خصوصی کردن شمارش نپسندیدن ویدیو در کل پلتفرم YouTube انجام می‌شود ، ویژگی statistics.dislikeCount منبع video از 13 دسامبر 2021 خصوصی می‌شود. به این معنی که این ویژگی فقط در پاسخ API از videos.list گنجانده می‌شود. اگر درخواست API توسط مالک ویدیو تأیید شده باشد، videos.list .

نقطه پایانی videos.rate تحت تأثیر این تغییر قرار نمی‌گیرد.

توسعه دهندگانی که تعداد نپسندیدن را به صورت عمومی نمایش نمی دهند و همچنان به تعداد عدم پسندیدن برای مشتری API خود نیاز دارند، می توانند برای قرار گرفتن در لیست مجاز برای معافیت درخواست دهند. برای درخواست معافیت، باید این فرم درخواست را تکمیل کنید.

می‌توانید در وبلاگ رسمی YouTube درباره این تغییر اطلاعات بیشتری کسب کنید.

2 ژوئیه 2021

توجه: این یک اعلامیه منسوخ شدن است.

نقطه پایانی commentThreads.update منسوخ شده است و دیگر پشتیبانی نمی شود. این قابلیت تکراری نقطه پایانی از طریق سایر نقاط پایانی API در دسترس است. در عوض، می توانید با comments.update تماس بگیرید

روش و اگر کد شما به منبع commentThreads نیاز دارد، یک فراخوان ثانویه با متد commentThreads.list برقرار کنید.

1 ژوئیه 2021

همه برنامه‌نویس‌هایی که از سرویس‌های API YouTube استفاده می‌کنند، باید یک حسابرسی انطباق با API انجام دهند تا بیش از سهمیه پیش‌فرض 10000 واحد به آنها اعطا شود. تا به امروز، هم فرآیند حسابرسی انطباق و هم درخواست‌ها برای تخصیص واحدهای سهمیه اضافی توسط توسعه‌دهندگانی که خدمات YouTube API را پر کرده و ارسال می‌کنند - فرم تمدید حسابرسی و سهمیه انجام شده است.

برای شفاف سازی این فرآیندها و پاسخگویی بهتر به نیازهای توسعه دهندگان با استفاده از خدمات API ما، سه فرم جدید و راهنمای تکمیل آن فرم ها را اضافه می کنیم:

فرم درخواست‌های توسعه‌دهنده حسابرسی شده : برنامه‌نویسانی که قبلاً یک حسابرسی انطباق API را گذرانده‌اند، می‌توانند این فرم کوتاه‌تر را برای درخواست تمدید سهمیه اختصاص‌یافته پر کرده و ارسال کنند.
فرم درخواست تجدیدنظر : توسعه دهندگانی که پروژه های API آنها در ممیزی انطباق شکست خورده است (یا از افزایش سهمیه رد شده اند) می توانند این فرم را پر کرده و ارسال کنند.
تغییر فرم کنترل : توسعه‌دهندگان یا هر طرفی که از طرف یک توسعه‌دهنده یک کلاینت API را اجرا می‌کند، که با تغییر کنترل (مثلاً از طریق خرید یا فروش سهام، ادغام یا سایر شکل‌های تراکنش شرکتی) مرتبط با یک پروژه API، تجربه می‌کنند. این فرم را پر کرده و ارسال کنید این به تیم API YouTube امکان می‌دهد سوابق ما را به‌روزرسانی کند، مطابقت موارد استفاده پروژه جدید API را بررسی کند و سهمیه فعلی توسعه‌دهنده را تأیید کند.

هر فرم جدید ما را از استفاده مورد نظر شما از API YouTube آگاه می کند و به ما امکان می دهد بهتر به شما کمک کنیم.

جزئیات بیشتر در راهنمای حسابرسی انطباق API جدید ما موجود است.

12 مه 2021

توجه: این یک اعلامیه منسوخ شدن است.

این به روز رسانی تغییرات API زیر را پوشش می دهد:

ویژگی contentDetails.relatedPlaylists.favorites منبع channel منسوخ شده است. عملکرد ویدیوهای مورد علاقه قبلاً برای چندین سال منسوخ شده است همانطور که در ورودی تاریخچه بازبینی در 28 آوریل 2016 ذکر شد.
قبل از این به‌روزرسانی، اگر یک کلاینت API بخواهد ویدیویی را به لیست پخش مورد علاقه‌های موجود اضافه کند، API همچنان یک لیست پخش جدید ایجاد می‌کند. در ادامه، لیست پخش در این حالت ایجاد نخواهد شد و API خطایی را برمی‌گرداند. تلاش‌ها برای تغییر فهرست‌های پخش دلخواه با افزودن، اصلاح یا حذف موارد نیز همه در اعلان‌های قبلی منسوخ شده‌اند و ممکن است در هر زمانی شروع به بازگشت خطا کنند.
ویژگی های منبع channel زیر منسوخ شده است. این ویژگی‌ها قبلاً در رابط کاربری YouTube Studio و YouTube پشتیبانی نمی‌شوند. در نتیجه، آنها دیگر از طریق API نیز پشتیبانی نمی شوند.
- brandingSettings.channel.defaultTab
- brandingSettings.channel.featuredChannelsTitle
- brandingSettings.channel.featuredChannelsUrls[]
- brandingSettings.channel.profileColor
- brandingSettings.channel.showBrowseView
- brandingSettings.channel.showRelatedChannels
همه ویژگی ها از نمایش منبع channel حذف شده اند و تعاریف آنها از لیست ویژگی های منبع حذف شده است. علاوه بر این، خطاهای مرتبط با این ویژگی ها از مستندات روش خاص حذف شده است.
ویژگی های منبع channelSection زیر منسوخ شده است. این ویژگی‌ها قبلاً در رابط کاربری YouTube Studio و YouTube پشتیبانی نمی‌شوند. در نتیجه، آنها دیگر از طریق API نیز پشتیبانی نمی شوند.
- snippet.style
- snippet.defaultLanguage
- snippet.localized.title
- localizations
- localizations.(key)
- localizations.(key).title
- targeting
- targeting.languages[]
- targeting.regions[]
- targeting.countries[]
در ارتباط با این تغییر، پارامتر hl روش channelSection.list نیز منسوخ شده است زیرا ویژگی هایی که پشتیبانی می کند پشتیبانی نمی شوند.
همه ویژگی ها از نمایش منبع channelSection حذف شده اند و تعاریف آنها از لیست ویژگی های منبع حذف شده است. علاوه بر این، خطاهای مرتبط با این ویژگی ها از مستندات روش خاص حذف شده است.
برای ویژگی snippet.type منبع channelSection ، مقادیر زیر منسوخ شده است. این مقادیر قبلاً در صفحات کانال YouTube پشتیبانی نمی‌شوند و در نتیجه، دیگر از طریق API نیز پشتیبانی نمی‌شوند.
- likedPlaylists
- likes
- postedPlaylists
- postedVideos
- recentActivity
- recentPosts
ویژگی snippet.tags[] منبع playlist منسوخ شده است. این ویژگی قبلاً در YouTube پشتیبانی نمی‌شود و در نتیجه، دیگر از طریق API پشتیبانی نمی‌شود.

9 فوریه 2021

منبع playlistItem از دو ویژگی جدید پشتیبانی می کند:

ویژگی snippet.videoOwnerChannelId شناسه کانالی را که ویدیوی لیست پخش را آپلود کرده است مشخص می کند.
ویژگی snippet.videoOwnerChannelTitle نام کانالی را که ویدیوی لیست پخش را آپلود کرده است مشخص می کند.

28 ژانویه 2021

این به روز رسانی شامل تغییرات زیر است:

روش های playlistItems.delete ، playlistItems.insert ، playlistItems.list ، playlistItems.update ، playlists.delete ، playlists.list و playlists.update همگی از یک خطای playlistOperationUnsupported جدید پشتیبانی می کنند. این خطا زمانی رخ می دهد که یک درخواست تلاش می کند عملیاتی را انجام دهد که برای یک لیست پخش خاص مجاز نیست. به عنوان مثال، کاربر نمی تواند یک ویدیو را از لیست پخش ویدیوهای آپلود شده خود حذف کند یا خود لیست پخش را حذف کند.
در همه موارد، این خطا کد پاسخ 400 HTTP (درخواست بد) را برمی گرداند.
خطاهای watchHistoryNotAccessible و watchLaterNotAccessible روش playlistItems.list از مستندات حذف شده است. در حالی که تاریخچه تماشای کاربران و لیست‌های تماشای بعدی، در واقع از طریق API قابل دسترسی نیستند، این خطاهای خاص توسط API بازگردانده نمی‌شوند.

15 اکتبر 2020

دو بخش جدید به سیاست های توسعه دهنده اضافه شده است:

بخش جدید III.E.4.i اطلاعات بیشتری درباره داده های جمع آوری و ارسال شده از طریق پخش کننده تعبیه شده YouTube ارائه می دهد. شما مسئول هر گونه اطلاعات کاربری هستید که از طریق هر پخش کننده جاسازی شده YouTube برای ما ارسال می کنید، قبل از اینکه کاربر با پخش کننده تعامل داشته باشد تا قصد پخش را نشان دهد. با تنظیم پخش خودکار روی نادرست، می‌توانید داده‌های به اشتراک گذاشته شده با YouTube را قبل از تعامل کاربر با پخش‌کننده محدود کنید.
بخش جدید III.E.4.j مربوط به بررسی وضعیت Made for Kids (MFK) محتوا قبل از جاسازی آن در سایت ها و برنامه های شما است. شما مسئول این هستید که بدانید چه زمانی ویدیوهایی که در API Client خود جاسازی می‌کنید برای کودکان ساخته شده‌اند و بر این اساس با داده‌های جمع‌آوری‌شده از پخش‌کننده جاسازی‌شده رفتار کنید. به این ترتیب، باید وضعیت محتوا را با استفاده از YouTube Data API Service قبل از جاسازی آن در API Client از طریق هر پخش کننده جاسازی شده YouTube بررسی کنید.

راهنمای جدید Finding the MadeForKids یک راهنمای ویدیویی نحوه جستجوی وضعیت MFK یک ویدیو را با استفاده از سرویس YouTube Data API توضیح می‌دهد.

در ارتباط با این تغییرات، یادآوری به مستندات پارامتر پخش کننده جاسازی شده اضافه شده است تا توضیح دهد که اگر پخش خودکار را فعال کنید، پخش بدون هیچ گونه تعامل کاربر با پخش کننده انجام می شود. بنابراین جمع‌آوری و اشتراک‌گذاری داده‌های پخش پس از بارگیری صفحه انجام می‌شود.

8 اکتبر 2020

این به روز رسانی سه تغییر کوچک مربوط به منبع channel را پوشش می دهد:

شی snippet.thumbnails ، که تصاویر کوچک کانال را شناسایی می کند، ممکن است برای کانال های تازه ایجاد شده خالی باشد و ممکن است یک روز طول بکشد تا پر شود.
ویژگی statistics.videoCount فقط تعداد ویدیوهای عمومی کانال را حتی برای مالکان منعکس می کند. این رفتار با تعداد نشان داده شده در وب سایت YouTube مطابقت دارد.
کلمات کلیدی کانال، که در ویژگی brandingSettings.channel.keywords مشخص می‌شوند، اگر از حداکثر طول مجاز 500 کاراکتر تجاوز کنند یا دارای علامت نقل قول غیرقابل فرار ( " ) باشند، ممکن است کوتاه شوند. توجه داشته باشید که محدودیت 500 نویسه برای هر محدودیت کلمه کلیدی بلکه محدودیتی در طول کل کلمات کلیدی است. این رفتار با رفتار وب سایت YouTube مطابقت دارد.

9 سپتامبر 2020

توجه: این یک اعلامیه منسوخ شدن است.

این به روز رسانی تغییرات API زیر را پوشش می دهد. همه تغییرات در تاریخ 9 سپتامبر 2020 یا بعد از این اعلامیه اعمال خواهند شد. با در نظر گرفتن این موضوع، توسعه دهندگان دیگر نباید به هیچ یک از ویژگی های API ذکر شده در زیر اعتماد کنند.

منابع، روش‌ها، پارامترها و ویژگی‌های منبع API زیر فوراً منسوخ شده‌اند و در تاریخ یا پس از این اعلامیه کار نمی‌کنند:
- ویژگی های منبع channel زیر:
  - ویژگی statistics.commentCount
  - شی brandingSettings.image و همه ویژگی های فرزند آن
  - فهرست brandingSettings.hints و همه ویژگی‌های فرزند آن
- پارامتر فیلتر categoryId روش channels.list
- منبع guideCategories و روش guideCategories.list
اگر درخواست API پارامتر managedByMe را روی true تنظیم کند، پاسخ‌های API برای روش channels.list دیگر حاوی ویژگی prevPageToken نیستند. این تغییر بر ویژگی prevPageToken برای سایر درخواست‌های channels.list تأثیر نمی‌گذارد و برای هیچ درخواستی بر ویژگی nextPageToken تأثیر نمی‌گذارد.
ویژگی های contentDetails.relatedPlaylists.watchLater و contentDetails.relatedPlaylists.watchHistory منبع channel هر دو در 11 اوت 2016 منسوخ اعلام شدند. پشتیبانی از روش playlistItems.insert و playlistItems.delete از این لیست‌های پخش نیز اکنون کاملاً منسوخ شده است و این دو ویژگی از اسناد حذف شده‌اند.
پارامتر mySubscribers روش channels.list ، که در 30 ژوئیه 2013 منسوخ اعلام شده بود، از اسناد حذف شده است. از روش subscriptions.list و پارامتر mySubscribers آن برای بازیابی لیستی از مشترکین کانال کاربر تأیید شده استفاده کنید.
شیء invideoPromotion منبع channel و همه ویژگی‌های فرزند آن، که در 27 نوامبر 2017 منسوخ اعلام شده بودند، از اسناد حذف شده‌اند.

29 جولای 2020

با حذف هزینه اضافی مربوط به پارامتر part ، فرآیند خود را برای دریافت سهمیه درخواست‌های API ساده کرده‌ایم. بلافاصله اعمال می شود، ما فقط هزینه پایه را برای روشی که فراخوانی می شود دریافت می کنیم. می توانید اطلاعات بیشتر در مورد سهمیه ساده شده را در اینجا بیابید.

تأثیر این تغییر این است که بیشتر تماس‌های API هزینه سهمیه‌ای کمتری خواهند داشت، در حالی که برخی از تماس‌های API همچنان همان هزینه را خواهند داشت. این تغییر هزینه تماس های API را افزایش نمی دهد. به طور کلی، تأثیر محتمل این است که سهمیه اختصاص داده شده شما، که در Google Cloud Console قابل مشاهده است، کمی فراتر خواهد رفت.

ما قویاً توصیه می‌کنیم که همه برنامه‌نویسان برای اطمینان از دسترسی مداوم به سرویس‌های YouTube API ، بازرسی انطباق پروژه‌های خود را انجام دهند.

این مدخل تاریخچه بازبینی در ابتدا در 20 ژوئیه 2020 منتشر شد.

28 جولای 2020

همه ویدیوهای آپلود شده از طریق videos.insert endpoint از پروژه‌های API تأیید نشده ایجاد شده پس از ۲۸ ژوئیه ۲۰۲۰ به حالت مشاهده خصوصی محدود می‌شوند. برای برداشتن این محدودیت، هر پروژه باید تحت بازرسی قرار گیرد تا مطابقت با شرایط خدمات را تأیید کند.

سازندگانی که از یک کلاینت API تأیید نشده برای آپلود ویدیو استفاده می‌کنند، ایمیلی دریافت می‌کنند که در آن توضیح می‌دهد که ویدیوی آن‌ها به‌عنوان خصوصی قفل شده است و می‌توانند با استفاده از یک مشتری رسمی یا حسابرسی شده از محدودیت جلوگیری کنند.

پروژه های API ایجاد شده قبل از 28 ژوئیه 2020 در حال حاضر تحت تأثیر این تغییر قرار نمی گیرند. با این حال، اکیداً توصیه می‌کنیم که همه برنامه‌نویسان برای اطمینان از دسترسی مداوم به سرویس‌های YouTube API ، بازرسی انطباق پروژه‌های خود را انجام دهند .

21 جولای 2020

[به‌روزرسانی در 28 ژوئیه 2020.] به‌روزرسانی اسنادی که در این مدخل تاریخچه بازبینی به آن اشاره شده است، در 28 ژوئیه 2020 مجدداً منتشر شد.

دیروز، ما یک به‌روزرسانی مستندات مربوط به فرآیند خود را برای شارژ سهمیه منتشر کردیم. اما به دلیل شرایط پیش بینی نشده، تغییر سهمیه هنوز اجرایی نشده است. در نتیجه، اسناد به منظور دقت برگردانده شده است. برای جلوگیری از سردرگمی، مدخل تاریخچه بازبینی که این تغییر را توضیح می‌دهد حذف شده است و در آینده نزدیک مجدداً منتشر خواهد شد.

7 جولای 2020

توجه: این یک اعلامیه منسوخ شدن است.

پارامترهای autoLevels و stabilize روش videos.insert اکنون منسوخ شده‌اند و هر دو پارامتر از مستندات حذف شده‌اند. مقادیر آنها نادیده گرفته می شود و بر نحوه پردازش ویدیوهای آپلود شده جدید تأثیری نمی گذارد.

15 ژوئن 2020

راهنمای جدید پیروی از خط‌مشی‌های برنامه‌نویس YouTube راهنمایی و مثال‌هایی را ارائه می‌کند تا به شما کمک کند مطمئن شوید که مشتریان API شما به بخش‌های خاصی از شرایط و خط‌مشی‌های خدمات YouTube API (API TOS) پایبند هستند.

این راهنما بینشی را در مورد چگونگی اجرای برخی جنبه‌های API TOS توسط YouTube ارائه می‌کند، اما هیچ سند موجود را جایگزین نمی‌کند. این راهنما به برخی از رایج ترین سوالاتی که توسعه دهندگان در طول ممیزی های انطباق API می پرسند، می پردازد. امیدواریم با کمک به درک نحوه تفسیر و اجرای خط‌مشی‌های خود، فرآیند توسعه ویژگی‌های شما را ساده‌تر کند.

4 ژوئن 2020

توجه: این به‌روزرسانی یک اعلامیه قبلی منسوخ شدن است.

ویژگی بولتن کانال اکنون به طور کامل منسوخ شده است. این تغییر ابتدا در 17 آوریل 2020 اعلام شد و اکنون اعمال شده است. در نتیجه، روش activities.insert دیگر پشتیبانی نمی‌شود، و روش activities.list دیگر بولتن‌های کانال را برمی‌گرداند. برای جزئیات بیشتر، لطفاً به مرکز راهنمایی YouTube مراجعه کنید.

17 آوریل 2020

توجه: این یک اعلامیه منسوخ شدن است.

یوتیوب ویژگی بولتن کانال را منسوخ می کند. در نتیجه، متد activities.insert منسوخ می‌شود و متد activities.list بازگرداندن بولتن‌های کانال را متوقف می‌کند. این تغییرات در 18 مه 2020 یا پس از آن در API اعمال خواهند شد. برای جزئیات بیشتر، لطفاً به مرکز راهنمایی YouTube مراجعه کنید.

31 مارس 2020

این به روز رسانی شامل تغییرات زیر است:

منابع و روش های جدید
- منبع member جدید نماینده یک کانال برای یک کانال YouTube است. یک عضو پشتیبانی پولی مکرر را از سازنده ارائه می‌کند و مزایای ویژه‌ای دریافت می‌کند. برای مثال، زمانی که سازنده حالت فقط اعضا را برای گپ روشن می‌کند، اعضا می‌توانند چت کنند.
  این منبع جایگزین منبع sponsor می شود که به عنوان بخشی از YouTube Live Streaming API مستند شده است. منبع sponsor اکنون منسوخ شده است و مشتریان API باید تماس ها را به روش sponsors.list به روز کنند تا به جای آن از روش members.list استفاده کنند.
- منبع جدید membershipsLevel سطح قیمتی را مشخص می کند که توسط سازنده ای که درخواست API را مجاز کرده است مدیریت می شود. متد membershipsLevels.list فهرستی از تمام سطوح عضویت سازنده را بازیابی می کند.

10 ژانویه 2020

API اکنون از توانایی شناسایی محتوای هدایت‌شده برای کودکان پشتیبانی می‌کند که YouTube آن را «ساخته شده برای کودکان» می‌نامد. در مرکز راهنمای YouTube درباره محتوای «ساخته شده برای کودکان» بیشتر بدانید .

channel و منابع video از دو ویژگی جدید پشتیبانی می‌کنند تا سازندگان محتوا و بینندگان بتوانند محتوایی را که برای کودکان ساخته شده است شناسایی کنند:

ویژگی selfDeclaredMadeForKids به سازندگان محتوا امکان می‌دهد مشخص کنند که کانال یا ویدیو برای کودکان ساخته شده است یا خیر.

برای کانال ها، این ویژگی را می توان هنگام فراخوانی روش channels.update تنظیم کرد. برای ویدیوها، این ویژگی را می توان هنگام فراخوانی روش های videos.insert یا videos.update تنظیم کرد.

توجه داشته باشید که این ویژگی فقط در پاسخ‌های API که حاوی منابع channel یا video هستند در صورتی گنجانده می‌شود که مالک کانال درخواست API را مجاز کرده باشد.
ویژگی madeForKids هر کاربری را قادر می‌سازد تا وضعیت «ساخته شده برای بچه‌ها» یک کانال یا ویدیو را بازیابی کند. برای مثال، وضعیت ممکن است بر اساس مقدار ویژگی selfDeclaredMadeForKids تعیین شود. برای اطلاعات بیشتر درباره تنظیم مخاطب برای کانال، ویدیوها یا پخش‌های خود، به مرکز راهنمایی YouTube مراجعه کنید.

ما همچنین شرایط خدمات YouTube API Services و خط‌مشی‌های برنامه‌نویس را به‌روزرسانی کرده‌ایم. لطفاً برای اطلاعات بیشتر به شرایط خدمات YouTube API Services - Revision History مراجعه کنید. تغییرات در شرایط خدمات YouTube API Services و خط‌مشی‌های برنامه‌نویس از 10 ژانویه 2020 به وقت اقیانوس آرام اعمال می‌شود.

10 سپتامبر 2019

اسناد مرجع API به‌روزرسانی شده است تا تغییری در نحوه گزارش تعداد مشترکین در YouTube و در نتیجه در پاسخ‌های API نشان دهد. در نتیجه این تغییر، تعداد مشترکین برگردانده شده توسط سرویس YouTube Data API به سه رقم قابل توجه برای تعداد مشترکین بیش از 1000 مشترک کاهش می یابد. این تغییر بر ویژگی statistics.subscriberCount منبع channel تأثیر می گذارد.

توجه: این تغییر حتی در مواردی که کاربر درخواست مجاز برای داده‌های مربوط به کانال خود را ارسال می‌کند، بر این مقدار ویژگی تأثیر می‌گذارد. مالکان کانال همچنان می‌توانند تعداد دقیق مشترکین را در استودیوی YouTube مشاهده کنند.

برای مثال، اگر کانالی 123456 مشترک داشته باشد، ویژگی statistics.subscriberCount حاوی مقدار 123000 خواهد بود. جدول زیر نمونه‌هایی از نحوه گرد کردن تعداد مشترکین در پاسخ‌های API و به اختصار در سایر رابط‌های کاربری YouTube قابل مشاهده برای عموم را نشان می‌دهد:

تعداد مشترکین نمونه	YouTube Data API	رابط‌های کاربری YouTube قابل مشاهده برای عموم
1,234	1230	1.23 هزار
12,345	12300	12.3 هزار
123,456	123000	123 هزار
1,234,567	1230000	1.23 میلیون
12,345,678	12300000	12.3 میلیون
123,456,789	123000000	123M

4 آوریل 2019

این به روز رسانی شامل تغییرات زیر است:

اسناد مرجع API برای توضیح بهتر موارد استفاده رایج برای هر روش و ارائه نمونه کد پویا و با کیفیت بالا از طریق ویجت APIs Explorer به روز شده است. برای مثال به مستندات روش channels.list مراجعه کنید. اکنون دو عنصر جدید در صفحات وجود دارد که روش‌های API را توصیف می‌کنند:
- ویجت APIs Explorer به شما امکان می‌دهد محدوده‌های مجوز را انتخاب کنید، پارامترهای نمونه و مقادیر ویژگی را وارد کنید، و سپس درخواست‌های API واقعی را ارسال کنید و پاسخ‌های API واقعی را ببینید. ویجت همچنین یک نمای تمام صفحه ارائه می دهد که نمونه های کامل کد را نشان می دهد که به صورت پویا برای استفاده از محدوده ها و مقادیری که وارد کرده اید به روز می شوند.
- بخش موارد استفاده متداول یک یا چند مورد استفاده متداول را برای روش توضیح داده شده در صفحه توضیح می دهد. برای مثال، می‌توانید برای بازیابی داده‌های مربوط به یک کانال خاص یا برای بازیابی داده‌های مربوط به کانال کاربر فعلی، روش channels.list را فراخوانی کنید.
  می‌توانید از پیوندهای موجود در آن بخش برای پر کردن APIs Explorer با مقادیر نمونه برای مورد استفاده خود یا برای باز کردن APIs Explorer تمام صفحه با مقادیری که قبلاً پر شده‌اند، استفاده کنید. هدف از این تغییرات، دیدن نمونه‌های کدی است که مستقیماً در مورد استفاده‌ای که می‌خواهید در برنامه کاربردی خود پیاده‌سازی کنید، قابل اجرا هستند.
نمونه کد در حال حاضر برای جاوا، جاوا اسکریپت، پی اچ پی، پایتون و کرل پشتیبانی می شود.
ابزار نمونه کد نیز با یک رابط کاربری جدید به روز شده است که همه ویژگی های مشابهی را که در بالا توضیح داده شد ارائه می دهد. با استفاده از آن ابزار، می‌توانید موارد استفاده را برای روش‌های مختلف کاوش کنید، مقادیر را در APIs Explorer بارگیری کنید، و APIs Explorer تمام صفحه را باز کنید تا نمونه‌های کد را در جاوا، جاوا اسکریپت، PHP و پایتون دریافت کنید.
در ارتباط با این تغییر، صفحاتی که قبلاً نمونه کدهای موجود برای جاوا، جاوا اسکریپت، پی اچ پی و پایتون را فهرست کرده بودند حذف شدند.
راهنماهای شروع سریع برای جاوا ، جاوا اسکریپت ، پی اچ پی و پایتون به روز شده است. راهنماهای اصلاح شده نحوه اجرای یک نمونه با کلید API و نمونه دیگر با شناسه مشتری OAuth 2.0 را با استفاده از نمونه کدهای APIs Explorer توضیح می دهند.

توجه داشته باشید که تغییرات توضیح داده شده در بالا جایگزین ابزار تعاملی می شود که در سال 2017 به اسناد API اضافه شده بود.

9 جولای 2018

این به روز رسانی شامل تغییرات زیر است:

تعریف ویژگی snippet.thumbnails منبع channel به‌روزرسانی شده است تا توجه داشته باشید که هنگام نمایش تصاویر کوچک در برنامه شما، کد شما باید از URLهای تصویر دقیقاً همانطور که در پاسخ‌های API برگردانده شده‌اند استفاده کند. به عنوان مثال، برنامه شما نباید از دامنه http به جای دامنه https در URL بازگردانده شده در یک پاسخ API استفاده کند.
از ژوئیه 2018، نشانی‌های اینترنتی تصاویر کوچک کانال فقط در دامنه https در دسترس خواهند بود، به این ترتیب نشانی‌های وب در پاسخ‌های API ظاهر می‌شوند. پس از آن زمان، اگر برنامه خود سعی کند تصاویر YouTube را از دامنه http بارگیری کند، ممکن است تصاویر شکسته را در برنامه خود مشاهده کنید.
توجه: این یک اعلامیه منسوخ شدن است.
ویژگی recordingDetails.location.altitude منبع video منسوخ شده است. هیچ تضمینی وجود ندارد که ویدیوها مقادیر این ویژگی را برگردانند. به طور مشابه، حتی اگر درخواست‌های API برای تعیین مقدار برای آن ویژگی تلاش کنند، ممکن است داده‌های دریافتی ذخیره نشوند.

22 ژوئن 2018

راهنمای پیاده‌سازی که قبلاً به‌عنوان راهنمای پیاده‌سازی و مهاجرت شناخته می‌شد، برای حذف دستورالعمل‌های مهاجرت از API v2 به API v3 به‌روزرسانی شده است. علاوه بر این، دستورالعمل‌هایی برای ویژگی‌هایی که از آن زمان در v3 API منسوخ شده‌اند، مانند ویدیوهای مورد علاقه، حذف شده‌اند.

27 نوامبر 2017

این به روز رسانی شامل تغییرات زیر است:

توجه: این یک اعلامیه منسوخ شدن است.
YouTube در حال حذف پشتیبانی از ویژگی‌های ویدیوی ویژه و وب‌سایت ویژه است که در API از طریق شیء invideoPromotion منبع channel پشتیبانی می‌شوند. در نتیجه، آن شی، از جمله تمام ویژگی‌های فرزند آن، منسوخ می‌شوند.
همچنان می‌توانید داده‌های invideoPromotion را تا 14 دسامبر 2017 بازیابی و تنظیم کنید. پس از آن تاریخ:
- تلاش برای بازیابی بخش invideoPromotion هنگام فراخوانی channels.list یک invideoPromotion خالی را برمی‌گرداند یا اصلاً هیچ داده invideoPromotion را بر نمی‌گرداند.
- تلاش برای به‌روزرسانی داده‌های invideoPromotion هنگام تماس با channels.update حداقل تا 27 مه 2018 پاسخ موفقیت‌آمیزی خواهد داشت، اما به‌عنوان غیرفعال تلقی می‌شوند، به این معنی که در واقع به‌روزرسانی انجام نمی‌دهند.
پس از 27 مه 2018، ممکن است این درخواست‌ها پیام‌های خطایی را برگردانند تا مثلاً نشان دهند که invalidPromotion یک بخش نامعتبر است.

16 نوامبر 2017

این به روز رسانی شامل تغییرات زیر است:

ابزار قطعه کد تعاملی اکنون از نمونه کدهای Node.js پشتیبانی می کند. نمونه ها همچنین در اسناد تقریباً همه روش های API، مانند روش channels.list ، قابل مشاهده هستند.
نمونه‌های قابل تنظیم به گونه‌ای طراحی شده‌اند که یک نقطه شروع خاص برای یک برنامه Node.js به شما ارائه دهند. عملکرد مشابه کد موجود در راهنمای شروع سریع Node.js است. با این حال، نمونه ها حاوی برخی از توابع کاربردی هستند که در شروع سریع ظاهر نمی شوند:
- تابع removeEmptyParameters فهرستی از جفت‌های کلید-مقدار مربوط به پارامترهای درخواست API را می‌گیرد و پارامترهایی را که مقادیری ندارند حذف می‌کند.
- تابع createResource فهرستی از جفت‌های کلید-مقدار مربوط به ویژگی‌های یک منبع API را می‌گیرد. سپس ویژگی ها را به یک شی JSON تبدیل می کند که می تواند در عملیات insert و update استفاده شود. مثال زیر مجموعه‌ای از نام‌ها و مقادیر ویژگی و شی JSON را نشان می‌دهد که کد برای آنها ایجاد می‌کند:
```
# Key-value pairs:
{'id': 'ABC123',
 'snippet.title': 'Resource title',
 'snippet.description': 'Resource description',
 'status.privacyStatus': 'private'}

# JSON object:
{
 'id': 'ABC123',
 'snippet': {
   'title': 'Resource title',
   'description': 'Resource description',

این به روز رسانی شامل تغییرات زیر است:

نمونه کدهای پایتون در ابزار قطعه کد تعاملی برای استفاده از کتابخانه های google-auth و google-auth-oauthlib به جای کتابخانه oauth2client که اکنون منسوخ شده است، به روز شده اند.
علاوه بر این تغییر، این ابزار اکنون نمونه‌های کد کاملی را برای برنامه‌های پایتون نصب شده و برنامه‌های وب سرور پایتون ارائه می‌کند که از جریان‌های مجوز کمی متفاوت استفاده می‌کنند. برای دیدن نمونه های کامل (و این تغییر):
1. به ابزار قطعه کد تعاملی یا اسناد مربوط به هر روش API، مانند روش channels.list بروید.
2. روی تب Python در بالای نمونه کد کلیک کنید.
3. برای جابجایی از دیدن یک قطعه به یک نمونه کامل، روی کلید بالای برگه ها کلیک کنید.
4. اکنون برگه باید یک نمونه کد کامل را نشان دهد که از جریان مجوز InstalledAppFlow استفاده می کند. توضیحات بالای نمونه این را توضیح می دهد و همچنین به نمونه ای برای یک برنامه وب سرور پیوند می دهد.
5. برای جابجایی به نمونه وب سرور، روی پیوند کلیک کنید. آن نمونه از چارچوب برنامه وب Flask و یک جریان مجوز متفاوت استفاده می کند.
همه این نمونه ها برای دانلود و اجرای محلی طراحی شده اند. اگر می‌خواهید نمونه‌ها را اجرا کنید، دستورالعمل‌های اجرای نمونه‌های کامل کد را به صورت محلی در دستورالعمل‌های ابزار قطعه کد ببینید.

29 آگوست 2017

این به روز رسانی شامل تغییرات زیر است:

تعریف پارامتر forContentOwner روش search.list به‌روزرسانی شده است تا توجه داشته باشید که اگر آن پارامتر روی true تنظیم شود، پارامتر type باید روی video تنظیم شود.
تعریف پارامتر regionCode روش search.list به روز شده است تا مشخص شود که این پارامتر نتایج جستجو را محدود به ویدیوهایی می کند که می توانند در منطقه مشخص شده مشاهده شوند.
یوتیوب لوگوها و نمادهای برند خود را به روز کرده است. آرم‌های جدید «توسعه یافته با YouTube» را می‌توانید از صفحه دستورالعمل‌های برندینگ دانلود کنید. سایر نشان‌واره‌ها و نمادهای YouTube نیز در آن صفحه نشان داده شده‌اند و می‌توانند از سایت برند YouTube دانلود شوند.

24 جولای 2017

این به روز رسانی شامل تغییرات زیر است:

راهنمای شروع سریع YouTube Data API برای iOS در دسترس است. راهنما نحوه استفاده از YouTube Data API را در یک برنامه ساده iOS که با Objective-C یا Swift نوشته شده است، توضیح می دهد.
ابزار قطعه کد تعاملی برای YouTube Data API اکنون شامل مستنداتی است که برخی از ویژگی های ابزار را توضیح می دهد:
- اجرای درخواست های API
- جابجایی بین قطعه کد و نمونه کد کامل
- استفاده از توابع دیگ بخار
- بارگیری منابع موجود (برای روش های به روز رسانی)
توجه: این ابزار همچنین در اسناد مرجع API برای روش های API تعبیه شده است ( مثال ).

1 ژوئن 2017

این به روز رسانی شامل تغییرات زیر است:

توجه: این یک اعلامیه منسوخ شدن است.
ویژگی های منبع video زیر در حال منسوخ شدن هستند. در حالی که ویژگی‌ها تا 1 دسامبر 2017 پشتیبانی می‌شوند، هیچ تضمینی وجود ندارد که ویدیوها تا آن زمان به بازگرداندن مقادیر برای آن ویژگی‌ها ادامه دهند. به طور مشابه، درخواست‌های videos.insert و videos.update که این مقادیر ویژگی را تنظیم می‌کنند، قبل از آن تاریخ خطا ایجاد نمی‌کنند، اما ممکن است داده‌های دریافتی ذخیره نشوند.

17 مه 2017

این به روز رسانی شامل تغییرات زیر است:

اسناد مرجع API به روز شده است تا تکه های کد را فراگیرتر و تعاملی تر کند. صفحاتی که روش‌های API را توضیح می‌دهند، مانند channels.list یا videos.rate ، اکنون دارای یک ابزار تعاملی هستند که به شما امکان می‌دهد قطعات کد را در جاوا، جاوا اسکریپت، PHP، Python، Ruby، Apps Script و Go مشاهده و سفارشی کنید.
برای هر روش معین ، ابزار قطعه های کد را برای یک یا چند مورد استفاده نشان می دهد ، و هر مورد استفاده یک روش مشترک برای فراخوانی آن روش را توصیف می کند. به عنوان مثال ، برای بازیابی داده ها در مورد یک کانال خاص یا در مورد کانال کاربر فعلی می توانید با روش channels.list تماس بگیرید.
همچنین می توانید با نمونه های کد ارتباط برقرار کنید:
- پارامتر و مقادیر خاصیت را اصلاح کنید ، و قطعه های کد به صورت پویا به روز می شوند تا مقادیر ارائه شده را منعکس کنند.
- بین قطعه های کد و نمونه های کامل جابجا شوید. یک قطعه کد بخشی از کدی را که روش API را صدا می کند نشان می دهد. یک نمونه کامل حاوی آن قطعه و همچنین کد دیگ بخار برای مجوز و ارسال درخواست است. نمونه های کامل را می توان از خط فرمان یا یک سرور وب محلی کپی و اجرا کرد.
- با کلیک روی یک دکمه ، درخواست ها را اجرا کنید. (برای اجرای درخواست ها ، شما باید به ابزار اجازه دهید تا از طرف شما با API تماس بگیرد.)
توجه داشته باشید که این ابزار جایگزین APIS Explorer در صفحات موجود در آن شده است. (هر صفحه پیوندی را نشان می دهد تا شما نیز گزینه بارگیری درخواستی را که در آن کار می کنید در APIS Explorer نیز داشته باشید.)
ابزار قطعه Code Code Data نیز با UI جدید به روز شده است که تمام ویژگی های مشابهی را که در بالا توضیح داده شده است ارائه می دهد. مهمترین ویژگی های جدید موجود در این صفحه عبارتند از:
- پشتیبانی از درخواست های API که داده می نویسند.
- پشتیبانی از نمونه های جاوا.
- کد دیگ بخار انعطاف پذیر و جامع تر برای مجاز کردن کاربران و ساخت درخواست های API.

27 آوریل 2017

این به روزرسانی شامل تغییرات زیر است:

راهنماهای جدید QuickStart نحوه تنظیم یک برنامه ساده را توضیح می دهد که درخواست های API داده YouTube را ایجاد می کند. راهنماها در حال حاضر برای Android ، Apps Script ، Go ، Java ، JavaScript ، Node.JS ، PHP ، Python و Ruby در دسترس هستند.

30 مارس 2017

این به روزرسانی شامل تغییرات زیر است:

Tostmetails.Topiccategories [] New channel Resource topicDetails.topicCategories[] شامل لیستی از URL های ویکی پدیا است که محتوای کانال را توصیف می کند. URL ها مطابق با شناسه های موضوعی است که در موضوع Resource's topicDetails.topicIds[] وجود دارد.
playlistItem Resource's New contentDetails.videoPublishedAt زمان انتشار این فیلم در یوتیوب را مشخص می کند. این منبع در حال حاضر حاوی خاصیت snippet.publishedAt است ، که زمان اضافه شدن این مورد به لیست پخش را مشخص می کند.
مانند منبع channel ، منبع video اکنون ویژگی topicDetails.topicCategories[] را برمی گرداند ، که حاوی لیستی از URL های ویکی پدیا است که محتوای این فیلم را توصیف می کند. برای منابع video ، URL ها با شناسه های موضوع برگشتی در موضوع topicDetails.relevantTopicIds[] .
contentDetails.contentRating.mpaatRating دارایی جدید این منبع video است ، رتبه بندی را که انجمن تصویر متحرک آمریکا به یک تریلر فیلم یا پیش نمایش داده است ، مشخص می کند.

27 فوریه 2017

همانطور که در ابتدا در 11 آگوست 2016 اعلام شد ، YouTube لیست پشتیبانی شده شناسه های موضوع را به یک لیست سرپرستی تغییر داده است. لیست کاملی از شناسه های موضوع پشتیبانی شده در ویژگی های topicDetails برای منابع channel و video و همچنین در پارامتر topicId search.list Method در گنجانده شده است.

توجه داشته باشید که چندین تغییر در لیست سرپرستی وجود دارد:

مباحث زیر به عنوان زیرمجموعه Society اضافه شده است:
نام شناسه موضوع
کسب و کار /m/09s1f
سلامتی /m/0kt51
نظامی /m/01h6rj
سیاست /m/05qt0
دین /m/06bvp
موضوع Animated cartoon ، که قبلاً کودک Entertainment بود ، حذف شده است.
موضوع Children's music ، که قبلاً کودک Music بود ، حذف شده است.

نام	شناسه موضوع
کسب و کار	`/m/09s1f`
سلامتی	`/m/0kt51`
نظامی	`/m/01h6rj`
سیاست	`/m/05qt0`
دین	`/m/06bvp`

در نتیجه این تغییر ، مباحث مربوط به یک فیلم اکنون همیشه در topicDetails.relevantTopicIds[] منبع video بازگردانده می شوند.

29 نوامبر 2016

این به روزرسانی شامل تغییرات زیر است:

سه تغییر کوچک در لیست شناسه های موضوع وجود دارد که از 10 فوریه 2017 پشتیبانی می شود:
- دسته Professional wrestling ، که قبلاً فرزند گروه Sports بود ، اکنون فرزند Entertainment است.
- دسته TV shows ، که کودک Entertainment است ، جدید است.
- گروه Health ، قبلاً فرزند Lifestyle ، برداشته شده است.
همچنین توجه داشته باشید که چند دسته والدین ( Entertainment ، Gaming ، Lifestyle ، Music و Sports ) وجود دارد. هر ویدئویی که با یک گروه کودک همراه باشد ، مانند Tennis ، با گروه والدین ( Sports ) نیز همراه خواهد بود.

10 نوامبر 2016

این به روزرسانی شامل تغییرات زیر است:

همانطور که برای اولین بار در 11 آگوست 2016 اعلام شد ، استهلاک FreeBase و API Freebase نیاز به چندین تغییر مربوط به شناسه های موضوع دارد. شناسه های موضوع مباحث مرتبط با منابع channel و video را شناسایی می کنند ، و همچنین می توانید از پارامتر جستجوی topicId برای یافتن کانال ها یا فیلم های مربوط به یک موضوع خاص استفاده کنید.
در تاریخ 10 فوریه 2017 ، YouTube به جای مجموعه بسیار گرانول تر از شناسه های برگشتی که تاکنون برگشته است ، شروع به بازگرداندن مجموعه کوچکی از شناسه های موضوع می کند. علاوه بر این ، توجه داشته باشید که کانال ها و فیلم ها تضمین نمی شوند که با هر موضوعی همراه باشند ، که با رفتار API فعلی سازگار است.
به طوری که می توانید مشتری های API خود را برای آن تغییرات آماده کنید ، تعاریف پارامترها و خصوصیات API زیر برای لیست شناسه های موضوع که پس از آن زمان پشتیبانی می شوند به روز شده اند. توجه داشته باشید که لیست دسته ها برای همه خصوصیات یکسان است.
- topicDetails.topicIds[] دارایی منابع channel .
- topicDetails.relevantTopicIds[] منبع video .
- پارامتر topicId search.list Method.
توجه: این یک اعلامیه استهلاک است.
خصوصیات زیر در حال کاهش است:
- topicDetails.topicIds[] دارایی منابع channel . این ملک تا 10 نوامبر 2017 پشتیبانی می شود.
- topicDetails.relevantTopicIds[] منبع video . این ملک تا 10 نوامبر 2017 پشتیبانی می شود.
- topicDetails.topicIds[] دارایی منبع video []. این topicDetails.relevantTopicIds[] شامل مقادیر بعد از 10 فوریه 2017 نخواهد بود.
از آنجا که FreeBase قبلاً کاهش یافته است ، راهنمای جستجوی موضوعات Freebase از مستندات حذف شده است. این راهنما نمونه های کد را برای نشان دادن نحوه کار یک برنامه با API Freebase ارائه می دهد.
علاوه بر این ، چندین نمونه کد مربوط به شناسه های موضوع از مستندات روش search.list حذف شده است.

2 نوامبر 2016

این به روزرسانی شامل تغییرات زیر است:

خصوصیات و پارامترهای جدید
- منبع video شامل چندین ویژگی جدید است:
  - ویژگی player.embedHtml حاوی یک برچسب <iframe> است که می توانید برای تعبیه بازیکنی که این فیلم را پخش می کند ، استفاده کنید. player.embedHeight و player.embedWidth Properties ابعاد بازیکن تعبیه شده را مشخص می کند. این خصوصیات فقط درصورتی بازگردانده می شوند که درخواست API حداقل یکی از پارامترهای maxHeight یا maxWidth را تعیین کند. این دو پارامتر جدید بعداً در این ورود تاریخچه تجدید نظر توضیح داده شده است.
  - ویژگی جدید hasCustomThumbnail نشان می دهد که آیا بارگذاری کننده ویدیو تصویر تصویربرداری سفارشی را برای این ویدئو ارائه داده است یا خیر. توجه داشته باشید که این ویژگی فقط برای بارگذاری کننده ویدیو قابل مشاهده است.
  - fpbRatingReasons[] دلایلی را که این فیلم رتبه FPB (آفریقای جنوبی) را دریافت کرده است ، مشخص می کند.
  - mcstRating جدید رتبه ای را که این فیلم در ویتنام دریافت کرده است ، مشخص می کند.
- روش videos.list از دو پارامتر جدید ، maxHeight و maxWidth پشتیبانی می کند. هنگام بازیابی قسمت player در منابع video می توانید از پارامتر یا هر دو پارامتر استفاده کنید.
  به طور پیش فرض ، ارتفاع <iframe> در player.embedHtml بازگشت 360px است. عرض برای مطابقت با نسبت ابعاد فیلم تنظیم می شود ، در نتیجه اطمینان می دهد که پخش کننده تعبیه شده دارای میله های سیاه نیست که این فیلم را قاب می کند. بنابراین ، به عنوان مثال ، اگر نسبت ابعاد یک فیلم 16: 9 باشد ، عرض بازیکن 640px خواهد بود.
  با پارامترهای جدید ، می توانید مشخص کنید که به جای ابعاد پیش فرض ، کد تعبیه شده باید از ارتفاع و/یا عرض مناسب برای طرح برنامه خود استفاده کند. سرور API ابعاد پخش کننده را در حد مناسب مقیاس می دهد تا اطمینان حاصل شود که پخش کننده تعبیه شده دارای میله های سیاه نیست که فیلم را قاب می کند. توجه داشته باشید که هر دو پارامتر حداکثر ابعاد پخش کننده تعبیه شده را مشخص می کنند. بنابراین ، اگر هر دو پارامتر مشخص شده باشند ، یک بعد ممکن است هنوز کوچکتر از حداکثر مقدار مجاز برای آن بعد باشد.
  به عنوان مثال ، فرض کنید یک فیلم نسبت ابعاد 16: 9 دارد. بنابراین ، اگر پارامتر maxHeight یا maxWidth تنظیم نشده باشد ، برچسب player.embedHtml حاوی یک بازیکن 640x360 است.
  - اگر پارامتر maxHeight روی 720 تنظیم شود و پارامتر maxWidth تنظیم نشده باشد ، API یک پخش کننده 1280x720 را برمی گرداند.
  - اگر پارامتر maxWidth روی 960 تنظیم شود و پارامتر maxHeight تنظیم نشده باشد ، API یک پخش کننده 960x540 را برمی گرداند.
  - اگر پارامتر maxWidth روی 960 تنظیم شود و پارامتر maxHeight روی 450 تنظیم شود ، API یک پخش کننده 800x450 را برمی گرداند.
  player.embedHeight و player.embedWidth Properties ، که در بالا توضیح داده شده است ، ابعاد بازیکن را مشخص می کند.
به روزرسانی در روش ها ، خصوصیات و پارامترها
- توضیحات منابع channelSection به روز شده است که توجه داشته باشید که یک کانال می تواند حداکثر 10 قفسه را بدون تنظیم داده های هدفمند ایجاد کند و می تواند حداکثر 100 قفسه را با داده های هدفمند ایجاد کند.
  علاوه بر این ، خاصیت targeting منابع channelSection به روز شده است تا این واقعیت را منعکس کند که گزینه های هدفمند فقط با استفاده از API قابل تنظیم هستند. اگر بخش کانال با استفاده از رابط کاربری در وب سایت YouTube اصلاح شود ، گزینه های هدفمند حذف می شوند.
- تعریف خاصیت snippet.name منبع i18nLanguage . name اصلاح شده است تا منعکس شود که این مقدار نام یک زبان را نشان می دهد همانطور که به زبان مشخص شده توسط پارامتر hl i18nLanguage.list نوشته شده است.
- playlistItem Resource's contentDetails.note ویژگی به روز شده است تا توجه داشته باشید که حداکثر طول ارزش خاصیت 280 کاراکتر است.
- contentDetails.startAt و contentDetails.endAt از playlistItem Resource PlaylistiTEM Resource Resource. این زمینه ها در صورت تنظیم در لیست های playlistItems.insert یا playlistItems.update نادیده گرفته می شوند.
- روشهای playlistItems.update playlistItems.delete onBehalfOfContentOwner درخواست هایی که از این روش استفاده می کنند نیز باید با یک نشانه مجاز باشند که دسترسی به https://www.googleapis.com/auth/youtubepartner را فراهم کند.
- پارامترهای publishedBefore و publishedAfter از روش search.list . بنابراین ، به عنوان مثال ، اگر پارامتر publishedBefore تنظیم شود ، API منابع ایجاد شده قبل یا در زمان مشخص شده را برمی گرداند.
- video contentDetails.contentRating.grfilmRating سه مقدار اضافی پشتیبانی می کند: grfilmK12 ، grfilmK15 و grfilmK18 .
- توضیحات روش videos.insert به روز شده است تا توجه داشته باشید که حداکثر اندازه پرونده برای فیلم های بارگذاری شده از 64 گیگابایت به 128 گیگابایت افزایش یافته است.

خطاهای جدید و به روز شده

API از خطاهای جدید زیر پشتیبانی می کند:

نوع خطا	جزئیات خطا	شرح
`forbidden (403)`	`homeParameterDeprecated`	روش `activities.list` این خطا را برمی گرداند تا نشان دهد که داده های فعالیت صفحه اصلی کاربر از طریق این API در دسترس نیست. اگر پارامتر `home` را در یک درخواست `true` تنظیم کنید ، ممکن است این خطا رخ دهد.
`invalidValue (400)`	`invalidContentDetails`	روش `playlistItems.insert` این خطا را برمی گرداند تا نشان دهد که شیء `contentDetails` در درخواست نامعتبر است. یکی از دلایلی که این خطا رخ می دهد این است که قسمت `contentDetails.note` از 280 کاراکتر طولانی تر است.
`forbidden (403)`	`watchHistoryNotAccessible`	روش `playlistItems.list` این خطا را برمی گرداند تا نشان دهد که این درخواست سعی در بازیابی موارد لیست پخش "Watch History" دارد ، اما این موارد را نمی توان با استفاده از API بازیابی کرد.
`forbidden (403)`	`watchLaterNotAccessible`	روش `playlistItems.list` این خطا را برمی گرداند تا نشان دهد که این درخواست سعی در بازیابی موارد لیست پخش "بعد از تماشای" دارد ، اما با استفاده از API قابل بازیابی نیست.
`badRequest (400)`	`uploadLimitExceeded`	روش `videos.insert` این خطا را برمی گرداند تا نشان دهد که کانال از تعداد فیلم هایی که ممکن است بارگذاری کند فراتر رفته است.
`forbidden (403)`	`forbiddenEmbedSetting`	روش `videos.update` این خطا را برمی گرداند تا نشان دهد که درخواست API سعی در تنظیم یک تنظیم تعبیه نامعتبر برای این فیلم دارد. توجه داشته باشید که برخی از کانال ها ممکن است اجازه ارائه بازیکنان تعبیه شده برای جریان های زنده نداشته باشند. برای اطلاعات بیشتر به مرکز راهنمای YouTube مراجعه کنید.

روش playlistItems.insert اگر یک فیلم تکراری را در لیست پخش وارد کنید ، دیگر خطایی را برنمی گرداند. این خطایی که قبلاً برای برخی از لیست های پخش مانند فیلم های مورد علاقه رخ داده است ، این اجازه را نمی دهد که کپی ها را مجاز نمی دانند اما دیگر پشتیبانی نمی شوند. به طور کلی ، لیست های پخش به فیلم های تکراری اجازه می دهند.

به روزرسانی های دیگر
- ورود تاریخچه تجدید نظر برای 15 سپتامبر 2016 ، به روز شده است تا روشن شود که ، هر زمان که محتوای channel . contentDetails.relatedPlaylists.watchHistory و contentDetails.relatedPlaylists.watchLater در پاسخ به ترتیب درج شده است ، آنها همیشه حاوی مقادیر HL و WL هستند. علاوه بر این ، این خصوصیات فقط در صورتی شامل می شوند که یک کاربر مجاز در حال بازیابی داده های مربوط به کانال خود کاربر باشد.

15 سپتامبر 2016

این به روزرسانی شامل تغییرات زیر است:

در تاریخ 11 آگوست 2016 ، به روزرسانی تاریخچه تجدید نظر در مورد چندین تغییر مربوط به شناسه های موضوع ، از جمله این واقعیت که مجموعه شناسه های موضوع پشتیبانی شده از 10 فوریه 2017 تغییر خواهد کرد. لیست مباحثی که پشتیبانی می شوند تا 10 نوامبر منتشر می شود ، 2016.
تغییرات زیر اکنون عملی شده است. اطلاع از این تغییرات در به روزرسانی تاریخچه تجدید نظر در 11 آگوست 2016 آورده شده است:
- اگر روش activities.list با پارامتر home تنظیم شده روی true فراخوانی شود ، پاسخ API اکنون شامل مواردی مشابه آنچه کاربر YouTube وارد شده در صفحه اصلی می بیند.
  این یک تغییر جزئی است که برای ارائه تجربه کاربری بهتر از رفتار شرح داده شده در به روزرسانی تاریخچه تجدید نظر در 11 آگوست 2016 در نظر گرفته شده است. این بروزرسانی اظهار داشت که درخواست ها با استفاده از پارامتر home یک لیست خالی را برمی گرداند.
- channel به ترتیب در حال حاضر به ترتیب برای همه کانال ها contentDetails.relatedPlaylists.watchHistory مقادیر HL و WL contentDetails.relatedPlaylists.watchLater .
  برای روشن شدن ، این خصوصیات فقط برای یک کاربر مجاز بازیابی داده های مربوط به کانال خود کاربر قابل مشاهده است. این خصوصیات همیشه حاوی مقادیر HL و WL است ، حتی برای یک کاربر مجاز که داده های مربوط به کانال خود کاربر را بازیابی می کند. بنابراین ، تاریخچه ساعت و تماشای شناسه های لیست پخش بعدی را نمی توان از طریق API بازیابی کرد.
  علاوه بر این ، درخواست ها برای بازیابی جزئیات لیست پخش ( playlists.list ) یا لیست های لیست پخش ( playlistItems.list ) برای تاریخچه تماشای یک کانال یا تماشای لیست پخش بعدی اکنون لیست های خالی را برمی گرداند. این رفتار برای مقادیر جدید ، HL و WL و همچنین برای هرگونه سابقه ساعت یا تماشای شناسه های لیست پخش بعدی که مشتری API شما قبلاً ذخیره کرده است ، صادق است.
منبع video fileDetails.recordingLocation شیء و خصوصیات کودک آن دیگر بازگردانده نمی شوند. پیش از این ، این داده ها (مانند Object fileDetails ) فقط توسط صاحب یک فیلم قابل بازیابی است.

11 آگوست 2016

این به روزرسانی شامل تغییرات زیر است:

خدمات خدمات تازه منتشر شده API YouTube API ("اصطلاحات به روز شده") ، که به تفصیل در وبلاگ مهندسی و توسعه دهندگان YouTube مورد بحث قرار گرفته است ، مجموعه ای غنی از به روزرسانی ها را به شرایط فعلی خدمات ارائه می دهد. علاوه بر اصطلاحات به روز شده ، که از تاریخ 10 فوریه 2017 به مرحله اجرا در خواهد آمد ، این بروزرسانی شامل چندین سند پشتیبانی برای کمک به توضیح سیاست هایی است که توسعه دهندگان باید دنبال کنند.
مجموعه کامل اسناد جدید در تاریخ تجدید نظر برای اصطلاحات به روز شده شرح داده شده است. علاوه بر این ، تغییرات آینده در اصطلاحات به روز شده یا در مورد اسناد حامی نیز در آن تاریخ تجدید نظر توضیح داده می شود. شما می توانید از پیوندی در آن سند در یک لیست لیست فید RSS مشترک شوید.
استهلاک Freebase و API Freebase باعث ایجاد چندین تغییر مربوط به شناسه های موضوع می شود. شناسه های موضوع در منابع و روشهای API زیر استفاده می شود:
- قسمت channel Resource's topicDetails مباحث مرتبط با کانال را مشخص می کند.
- قسمت topicDetails منبع video مباحث مرتبط با این فیلم را مشخص می کند.
- پارامتر topicId search.list MethodID به شما امکان می دهد فیلم ها یا کانال های مربوط به یک موضوع خاص را جستجو کنید.
تغییرات در این ویژگی ها عبارتند از:
- از تاریخ 10 فوریه 2017 ، YouTube به جای مجموعه بسیار دانه ای تر از شناسه های برگشتی که تاکنون برگشته است ، شروع به بازگرداندن مجموعه کوچکی از شناسه های موضوع می کند. این مجموعه از موضوعات پشتیبانی شده ، دسته بندی های سطح بالا مانند ورزش یا بسکتبال را شناسایی می کند ، اما به عنوان مثال ، آنها تیم ها یا بازیکنان خاصی را شناسایی نمی کنند. ما مجموعه ای از موضوعات پشتیبانی شده را اعلام خواهیم کرد تا شما وقت خود را برای آماده سازی برنامه خود برای این تغییر داشته باشید.
- هر شناسه موضوع FreeBase که قبلاً بازیابی کرده اید می تواند برای جستجوی محتوا تا 10 فوریه 2017 استفاده شود. با این حال ، پس از آن زمان ، شما قادر خواهید بود فقط از مجموعه های کوچکتر از موضوعات مشخص شده در مورد قبلی استفاده کنید تا نتایج جستجو را بازیابی کنید موضوع.
- پس از 10 فوریه 2017 ، اگر سعی می کنید با استفاده از شناسه موضوع که در مجموعه کوچکتر از شناسه های موضوعی پشتیبانی شده نیست ، نتایج را جستجو کنید ، API یک مجموعه نتیجه خالی را برمی گرداند.
چندین زمینه و پارامترهای API در 12 سپتامبر 2016 به طور مؤثر کاهش می یابد:
- پارامتر home Method activities.list یک کاربر مجاز را قادر می سازد تا فید فعالیتی را که در صفحه اصلی YouTube برای آن کاربر نمایش می دهد ، بازیابی کند. درخواست هایی که از این پارامتر بعد از 12 سپتامبر 2016 استفاده می کنند ، یک لیست خالی را برمی گردانند.
- channel فقط برای یک کاربر مجاز بازیابی contentDetails.relatedPlaylists.watchHistory در مورد کانال شخصی کاربر contentDetails.relatedPlaylists.watchLater مشاهده است. پس از 12 سپتامبر 2016 ، contentDetails.relatedPlaylists.watchHistory یک مقدار HL را برمی گرداند و contentDetails.relatedPlaylists.watchLater دارایی برای همه کانال ها ارزش WL را برمی گرداند.
  درخواست های بازیابی جزئیات لیست پخش ( playlists.list ) برای تاریخچه تماشای یک کانال یا تماشای لیست پخش بعدی بعد از 12 سپتامبر 2016 یک لیست خالی را باز می گرداند. درخواست های بازیابی موارد لیست پخش (لیست playlistItems.list . بعد از آن زمان لیست کنید. این در مورد مقادیر جدید ، HL و WL ، و همچنین برای هرگونه تاریخچه ساعت یا تماشای شناسه های لیست پخش بعدی که ممکن است مشتری API شما قبلاً ذخیره کرده باشد ، صادق است.
- fileDetails.recordingLocation از منابع video یا هر یک از خصوصیات کودک آن دیگر پس از 12 سپتامبر 2016 بازگردانده نمی شود. این داده ها فقط توسط صاحب یک ویدیو قابل بازیابی هستند زیرا والدین fileDetails فقط توسط یک صاحب ویدیو قابل بازیابی هستند.

13 ژوئن 2016

این به روزرسانی شامل تغییرات زیر است:

contentDetails.googlePlusUserId از منابع channel کمبود شده است. پیش از این ، این ویژگی تنها در صورتی که کانال با نمایه Google+ همراه بود ، موجود بود. پس از استهلاک ، این ملک دیگر در هیچ منبع channel گنجانده نمی شود.
snippet.authorGoogleplusProfileUrl از منبع comment کمبود شده است. پیش از این ، این ویژگی تنها در صورتی که کانال با نمایه Google+ همراه بود ، موجود بود. پس از استهلاک ، این ملک دیگر در هیچ منبع comment گنجانده نمی شود.

از آنجا که هیچ یک از این خصوصیات به دنبال استهلاک بازگردانده نمی شوند ، هر دو ویژگی از مستندات منابع مربوطه حذف نشده اند.

31 مه 2016

این به روزرسانی شامل تغییرات زیر است:

پارامتر جدید myRecentSubscribers روش subscriptions.list . لیستی از مشترکان کانال کاربر تأیید شده را به ترتیب زمانی معکوس از زمان مشترک در کانال بازیابی می کند.
توجه داشته باشید که پارامتر جدید فقط از بازیابی 1000 مشترک جدید در کانال کاربر تأیید شده پشتیبانی می کند. برای بازیابی لیست کاملی از مشترکان ، از پارامتر mySubscribers استفاده کنید. این پارامتر ، که مشترکان را به ترتیب خاصی باز نمی گرداند ، تعداد مشترکانی را که می توان بازیابی کرد محدود نمی کند.
تعریف snippet.thumbnails.(key) خاصیت برای فعالیت ، لیست پخش ، لیست پخش ، نتیجه جستجو ، تصویر کوچک و ویدیویی به روز شده است تا توجه داشته باشید که اندازه تصویر کوچک تصویر کوچک برای برخی از فیلم ها در دسترس است.
- تصویر standard 640px عرض و 480px قد دارد.
- تصویر maxres 1280px عرض و 720px قد دارد.
تعریف پارامتر part channelSection.list Method به روز شده است تا توجه داشته باشید که قسمت targeting را می توان با هزینه 2 واحد سهمیه بازیابی کرد.
روش videos.list اکنون خطایی ممنوعه ( 403 ) را برمی گرداند که یک درخواست مجاز به طور نادرست سعی در بازیابی fileDetails ، processingDetails یا suggestions بخش هایی از یک منبع video دارد. این قسمت ها فقط در اختیار صاحب فیلم است.

17 مه 2016

ابزار جدید قطعه کد API Code ، قطعه های کد کوتاه را برای موارد استفاده API در مورد داده های YouTube متداول فراهم می کند. قطعه های کد در حال حاضر برای کلیه روشهای API فقط خواندنی در برنامه های Script ، Go ، JavaScript ، PHP ، Python و Ruby در دسترس هستند.

برای هر روش ، ابزار نمونه های کد را برای یک یا چند مورد استفاده نشان می دهد. به عنوان مثال ، این روش پنج کد را برای روش search.list فراهم می کند.

لیست فیلم ها بر اساس کلمه کلیدی
فیلم ها را بر اساس مکان لیست کنید
لیست رویدادهای زنده
فیلم های کاربر معتبر را جستجو کنید
لیست فیلم های مرتبط

برای هر مورد استفاده ، ابزار پارامترهای مورد استفاده در درخواست API را نشان می دهد. می توانید مقادیر پارامتر را تغییر دهید ، در این حالت ابزار قطعه کد را به روز می کند تا مقادیر پارامتر ارائه شده را منعکس کند.

سرانجام ، ابزار پاسخ API را به هر درخواست نشان می دهد. اگر پارامترهای درخواست را اصلاح کرده اید ، پاسخ API بر اساس مقادیر پارامتر ارائه شده شما است. توجه داشته باشید که برای نمایش پاسخ های API باید به ابزاری برای ارسال درخواست ها از طرف خود اجازه دهید.

28 آوریل 2016

این به روزرسانی شامل تغییرات زیر است:

ویژگی جدید contentDetails.projection از منبع video قالب پیش بینی فیلم را مشخص می کند. مقادیر معتبر خاصیت 360 و rectangular است.
video و fileDetails.recordingLocation recordingDetails.location دو به روز شده اند تا تفاوت بین این دو ویژگی را توضیح دهند:
- ویژگی recordingDetails.location مکانی را که صاحب فیلم می خواهد با این ویدئو در ارتباط باشد ، مشخص می کند. این مکان قابل ویرایش است ، در فیلم های عمومی قابل جستجو است و ممکن است برای فیلم های عمومی برای کاربران نمایش داده شود.
- مقدار خاصیت fileDetails.recordingLocation تغییر ناپذیر است و مکان مرتبط با پرونده ویدیویی بارگذاری شده اصلی را نشان می دهد. این مقدار فقط برای صاحب فیلم قابل مشاهده است.
تعریف از contentDetails.relatedPlaylists.favorites به عنوان تعریف از منابع channel به روز شده است تا توجه داشته باشید که مقدار خاصیت ممکن است حاوی یک شناسه لیست پخش باشد که به یک لیست پخش خالی اشاره دارد و نمی توان آن را بدست آورد. این به این دلیل است که عملکرد فیلم های مورد علاقه قبلاً کاهش یافته است. توجه داشته باشید که این ملک مشمول سیاست استهلاک API نیست .
تعریف خطای ineligibleAccount ، که می تواند توسط comments.insert ، comments.update ، commentThreads.insert یا commentThreads.update برگردانده شود ، به روز شده است تا منعکس شود که خطا در هنگام استفاده از حساب YouTube برای مجاز بودن درخواست API رخ می دهد. با حساب Google کاربر ادغام نشده است.

20 آوریل 2016

این به روزرسانی شامل تغییرات زیر است:

تعریف پارامتر part channels.update به روز شده است تا توجه داشته باشید که localizations نیز یک مقدار معتبر برای آن پارامتر است.
بخش استفاده از سهمیه راهنمای شروع کار برای پیوند به کنسول توسعه دهنده Google به روز شده است ، جایی که می توانید سهمیه واقعی و استفاده از سهمیه خود را مشاهده کنید.

16 مارس 2016

این به روزرسانی شامل تغییرات زیر است:

به روز رسانی منابع و روشهای موجود
- مستندات منابع channelBanner به روز شده است تا توجه داشته باشد که اندازه توصیه شده برای تصویر بنر کانال بارگذاری شده تا 1440px 2560px است. حداقل اندازه (2048px با 1152px) تغییر نکرده است.
- ویژگی جدید channel Resource snippet.customUrl URL سفارشی مرتبط با کانال را مشخص می کند. (همه کانال ها دارای URL های سفارشی نیستند.) مرکز کمک YouTube الزامات لازم برای دریافت URL سفارشی و همچنین نحوه تنظیم URL را توضیح می دهد.
- Object brandingSettings.watch Resource channel و تمام خصوصیات کودک آن کاهش یافته است.
- پاسخ API به یک درخواست search.list اکنون شامل یک ویژگی regionCode است. این ملک کد منطقه ای را که برای جستجوی جستجو استفاده شده است ، مشخص می کند. کد منطقه به API دستور می دهد تا نتایج جستجو را برای کشور مشخص بازگرداند.
  مقدار خاصیت یک کد کشور دو حرفی است که منطقه را مشخص می کند. روش i18nRegions.list لیستی از مناطق پشتیبانی شده را برمی گرداند. مقدار پیش فرض US . اگر یک منطقه غیر پشتیبانی مشخص شده باشد ، YouTube ممکن است هنوز منطقه دیگری را به جای مقدار پیش فرض انتخاب کند تا از پرس و جو استفاده کند.
- تعاریف مربوط به snippet.label و snippet.secondaryReasons[].label منبع videoAbuseReportReason Resource.
  علاوه بر این ، روش videoAbuseReportReasons.list اکنون از پارامتر hl پشتیبانی می کند ، که زبانی را که باید برای متن برچسب در پاسخ API استفاده شود ، مشخص می کند. مقدار پارامتر پیش فرض en_US است.
- contentDetails.contentRating.ecbmctRating دارایی جدید این منبع video است. رتبه یک فیلم را از هیئت ارزیابی و طبقه بندی ترکیه از وزارت فرهنگ و گردشگری مشخص می کند.
  علاوه بر این ، خصوصیات API برای سایر سیستم های رتبه بندی از مقادیر خاص خاص زیر پشتیبانی می کند:
  - contentDetails.contentRating.fpbRating (آفریقای جنوبی)
    امتیاز: 10 ؛ ارزش خاصیت: fpb10
  - contentDetails.contentRating.moctwRating (تایوان)

API از خطاهای جدید زیر پشتیبانی می کند:

نوع خطا	جزئیات خطا	شرح
`badRequest (400)`	`notEditable`	`channelSections.insert` ، `channelSections.update` و `channelSections.delete` این خطا را برمی گردانند تا نشان دهد که بخش کانال مشخص شده نمی تواند ایجاد ، به روز شده یا حذف شود.
`badRequest (400)`	`styleRequired`	روش های `channelSections.insert` و `channelSections.update` این خطا را برمی گرداند تا نشان دهد که منبع `channelSection` ارسال شده در درخواست API باید یک مقدار را برای خاصیت `snippet.style` مشخص کند.
`badRequest (400)`	`typeRequired`	`channelSections.insert` و `channelSections.update` این خطا را برمی گرداند تا نشان دهد که منبع `channelSection` ارسال شده در درخواست API باید یک مقدار را برای خاصیت `snippet.type` مشخص کند.
`badRequest (400)`	`processingFailure`	روش `commentThreads.list` این خطا را برمی گرداند تا نشان دهد سرور API نتوانسته است درخواست را با موفقیت پردازش کند. در حالی که این می تواند یک خطای گذرا باشد ، معمولاً نشان می دهد که ورودی درخواست نامعتبر است. برای اطمینان از اعتبار آن ، ساختار منبع `commentThread` را در بدنه درخواست بررسی کنید.
`forbidden (403)`	`commentsDisabled`	روش `commentThreads.list` این خطا را برمی گرداند تا نشان دهد که ویدیوی مشخص شده توسط پارامتر `videoId` نظرات را غیرفعال کرده است.
`badRequest (400)`	`commentTextTooLong`	روش `commentThreads.insert` این خطا را برمی گرداند تا نشان دهد که منبع `comment` که در حال وارد شدن است ، شامل شخصیت های زیادی در `snippet.topLevelComment.snippet.textOriginal` است.
`invalidValue (400)`	`videoAlreadyInAnotherSeriesPlaylist`	روش `playlistItems.insert` این خطا را برمی گرداند تا نشان دهد این ویدئویی که می خواهید به لیست پخش اضافه کنید ، در لیست پخش سری دیگری قرار دارد. برای کسب اطلاعات بیشتر در مورد لیست های پخش سری ، به مرکز راهنمای YouTube مراجعه کنید.
`badRequest (400)`	`subscriptionForbidden`	روش `subscriptions.insert` این خطا را برمی گرداند تا نشان دهد که به حداکثر اشتراک های خود رسیده اید یا اشتراک های اخیر بیش از حد ایجاد کرده اید. در حالت دوم ، می توانید پس از چند ساعت درخواست را دوباره امتحان کنید.
`badRequest (400)`	`invalidCategoryId`	روش `videos.update` این خطا را برمی گرداند تا نشان دهد که خاصیت `snippet.categoryId` در منبع `video` بارگذاری شده ، شناسه دسته نامعتبر را مشخص می کند. برای بازیابی دسته های پشتیبانی شده از روش `videoCategories.list` استفاده کنید.

قوانین اتحادیه اروپا (اتحادیه اروپا) مستلزم آن است که افشای خاصی باید به آنها داده شود و رضایت های به دست آمده از کاربران نهایی در اتحادیه اروپا. بنابراین ، برای کاربران نهایی در اتحادیه اروپا ، شما باید خط مشی رضایت کاربر اتحادیه اروپا را رعایت کنید. ما در شرایط خدمات API YouTube خود ، اخطار این نیاز را اضافه کرده ایم.

19 نوامبر 2015

API اکنون از توانایی تنظیم و بازیابی متن بومی شده برای snippet.title و snippet.description از playlist و منابع video ، خاصیت snippet.title منبع channelSection و خاصیت snippet.description از منابع channel پشتیبانی می کند.

تنظیم عناوین و توضیحات بومی شده
می توانید هنگام تماس با روش insert یا update برای آن منبع ، مقادیر بومی سازی شده را برای یک منبع تنظیم کنید. برای تنظیم مقادیر بومی شده برای یک منبع ، هر دو مورد را انجام دهید:
- اطمینان حاصل کنید که یک مقدار برای خاصیت snippet.defaultLanguage منبع تنظیم شده است. این خاصیت زبان snippet.title و snippet.description را مشخص می کند. ارزش آن می تواند هر زبان برنامه پشتیبانی شده یا سایر کدهای زبانی ISO 639-1: 2002 باشد. به عنوان مثال ، اگر ویدئویی را که دارای عنوان و توضیحات انگلیسی است بارگذاری کنید ، ویژگی snippet.defaultLanguage را روی en قرار می دهید.
  توجه داشته باشید برای به روزرسانی منابع channel : برای تنظیم ویژگی snippet.defaultLanguage برای یک منبع channel ، در واقع باید ویژگی های brandingSettings.channel.defaultLanguage را به روز کنید.
- شیء localizations را به منبعی که به روز می کنید اضافه کنید. هر کلید شیء رشته ای است که یک زبان برنامه یا کد زبان ISO 639-1: 2002 را مشخص می کند ، و هر یک از کلیدها را به یک شیء که شامل عنوان (و توضیحات) برای منبع است ، نقشه می کند.
  قطعه نمونه زیر زبان پیش فرض منبع را به انگلیسی تنظیم می کند. همچنین عناوین و توضیحات بومی آلمانی و اسپانیایی را به یک فیلم اضافه می کند:
```
{
  "kind": "youtube#video",
  ...
  "snippet": {
    "title": "Playing soccer",
    "description": "We play soccer in the park on Sundays.",
    "defaultLanguage": "en",
    ...
  },
  "localizations":
    "de": {
      "title": "Fußball spielen",
      "description": "Wir spielen Fußball im Park am Sonntag"
    },
    "es": {
      "title": "Jugar al fútbol",
      "description": "Nosotros jugamos fútbol en el parque los domingos",
    }
  }
}
```
بازیابی مقادیر بومی شده
The API supports two ways to retrieve localized values for a resource:
- Add the hl parameter to your channels.list , channelSections.list , playlists.list , or videos.list request to retrieve localized data for a specific application language that the YouTube website supports . If localized resource details are available in that language, the resource's snippet.localized object will contain the localized values. However, if localized details are not available, the snippet.localized object will contain resource details in the resource's default language .
  For example, suppose a videos.list request retrieved data for the video described above with localized German and Spanish data. If the hl parameter were set to de , the resource would contain the following data:
```
{
  "kind": "youtube#video",
  ...
  "snippet": {
    "title": "Playing soccer",
    "description": "We play soccer in the park on Sundays.",
    "defaultLanguage": "en",
    "localized": {
      "title": "Fußball spielen",
      "description": "Wir spielen Fußball im Park am Sonntag"
    }
    ...
  }
}
```
  However, if the hl parameter were set to fr , the snippet.localized object would contain the English title and description because English is the default language for the resource, and localized French details are not available.
  Important: The hl parameter only supports values that identify application languages that the YouTube website supports. To determine whether localized text is available for other languages, you need to retrieve the localizations part for the resource and filter to determine whether the localized text exists.
  
  For example, you would need to retrieve the full list of localizations to determine whether localized text is available in Appalachian English.
- When retrieving a resource, include localizations in the part parameter value to retrieve all of the localized details for that resource. If you are retrieving localized data for a language that is not a current YouTube application language , you need to use this approach to retrieve all localizations and then filter to determine whether the desired localized data exists.

Errors related to localized text values

The API also supports the following new errors for localized text values:

نوع خطا	جزئیات خطا	شرح
`badRequest (400)`	`defaultLanguageNotSetError`	This error indicates that a request that tries to insert or update the `localizations` object for a resource is failing because the `snippet.defaultLanguage` property is not set for that resource. The `channels.update` , `channelSections.insert` , `channelSections.update` , `playlists.insert` , `playlists.update` , `videos.insert` , and `videos.update` methods support this error.
`badRequest (400)`	`localizationValidationError`	This error indicates that one of the values in a resource's `localizations` object failed to validate. For example, this error might occur if the object contains an invalid language code. The `channels.update` , `channelSections.insert` , `channelSections.update` , `playlists.insert` , and `playlists.update` methods support this error.

4 نوامبر 2015

This update contains the following changes:

Updates to existing resources and methods
- The search.list method's order parameter has been updated to note that if you sort live broadcasts by viewCount , the API results are sorted by the broadcasts' number of concurrent viewers while the broadcasts are still ongoing.
- The search.list method's relatedToVideoId parameter has been updated to note that if the parameter is set, the only other supported parameters are part , maxResults , pageToken , regionCode , relevanceLanguage , safeSearch , type (which must be set to video ), and fields . This update does not reflect a change in API behavior.
- The definition of the video resource's snippet.publishedAt property has been updated to note that the property value, which specifies the date and time that the video was published, might be different than the time that the video was uploaded. For example, if a video is uploaded as a private video and then made public at a later time, the property value specifies the time that the video was made public. The updated definition also explains how the value is populated for private and unlisted videos.
  This change does not reflect a change in API behavior.
- The definition of the video resource's status.publishAt property has been updated to note:
  - If you set this property's value when calling the videos.update method, you must also set the status.privacyStatus property value to private even if the video is already private.
  - If the request schedules a video to be published at some time in the past, it is published right away. As such, the effect of setting the status.publishAt property to a past date and time is the same as of changing the video's privacyStatus from private to public .
- The video resource's contentDetails.contentRating.cncRating property specifies the video's rating from France's Commission de classification cinematographique. This property replaces the contentDetails.contentRating.fmocRating property, which is now deprecated.
- The definition of the channel resource's brandingSettings.channel.keywords has been updated to correctly reflect that the property value contains a space-separated list of strings and not a comma-separated list, as previously documented. This update does not reflect a change in API behavior.
- The documentation for the thumbnails.set method has been updated to accurately reflect that the body of the request contains the thumbnail image that you are uploading and associating with a video. The request body does not contain a thumbnail resource. Previously, the documentation said that you should not provide a request body when calling this method. This update does not reflect a change in API behavior.
- The description of the activity resource has been updated to reflect the fact that the activities.list method does not currently include resources related to new video comments. The resource's snippet.type and contentDetails.comment have been updated as well.

New and updated errors

The API now supports the following errors:

This update contains the following changes:

Updates to existing resources and methods
- The video resource's statistics.favoriteCount property has been deprecated.
  In accordance with our deprecation policy, this property will continue to be included in video resources for at least one year after this announcement. However, the property value is now always set to 0 .

7 آگوست 2015

This update contains the following changes:

Updates to existing resources and methods
- The definition of the video resource's snippet.tags[] property has been updated to provide more information about how the API server calculates the length of the property's value. Note that this update does not reflect a change in the API's behavior.
  Specifically, the definition now explains that if a tag contains a space, the API server handles the tag value as though it were wrapped in quotation marks, and the quotation marks count toward the character limit. So, for the purposes of character limits, the tag Foo-Baz contains seven characters, but the tag Foo Baz contains nine characters.
- The commentThreads.insert method no longer supports the shareOnGooglePlus parameter, which previously indicated whether a comment and replies to that comment should also be posted to the author's Google+ profile. If a request submits the parameter, the API server ignores the parameter but otherwise handles the request.

18 ژوئن 2015

This update contains the following changes:

Updates to existing resources and methods
- The commentThreads.list method's new order parameter specifies the order in which the API response should list comment threads. Threads can be ordered by time or relevance. The default behavior is to order them by time.
- The video resource's new snippet.defaultAudioLanguage property specifies the language spoken in the video's default audio track.
- The definition of the video resource's contentDetails.licensedContent property has been updated to clarify that the content must have been originally uploaded to a channel linked to a YouTube content partner and then claimed by that partner. This does not represent a change in actual API behavior.
- The captions.delete , captions.download , captions.insert , captions.list , and captions.update methods now support the onBehalfOfContentOwner parameter, which is already supported for several other methods. Requests that use that method also need to be authorized with a token that provides access to the https://www.googleapis.com/auth/youtubepartner scope.

New and updated errors

The API now supports the following errors:

دلیل	`emailNotVerified`
شرح	The user must verify her email address prior to rating the video.

videos.rate

HTTP Response Code	`badRequest (400)`
دلیل	`videoPurchaseRequired`
شرح	Rental videos can only be rated by users who rented them.

The subscriptions.delete and subscriptions.insert methods no longer support the accountClosed and accountSuspended errors.

27 آوریل 2015

This update contains the following changes:

New resources and methods
- The new videoAbuseReportReason resource contains information about a reason that a video would be flagged for containing abusive content. The videoAbuseReportReasons.list method lets you retrieve a list of all of the reasons why videos might be flagged.
- The new videos.reportAbuse method provides a way to actually flag a video that contains abusive content. The body of the request contains a JSON object that specifies the video being flagged as well as the reason that the video is deemed to contain abusive content. Valid reasons can be obtained from the videoAbuseReportReason.list method described above.
  The migration guide has also been updated with an example for reporting an abusive video. With this change, the v3 API now supports all of the v2 API features that it is scheduled to support. These features are also all explained in the migration guide.
Updates to existing resources and methods
- The search.list method's new forDeveloper filter parameter restricts a search to only retrieve videos uploaded via the developer's application or website. The forDeveloper parameter can be used in conjunction with optional search parameters like the q parameter.
  For this feature, each uploaded video is automatically tagged with the project number that is associated with the developer's application in the Google Developers Console .
  When a search request subsequently sets the forDeveloper parameter to true , the API server uses the request's authorization credentials to identify the developer. Therefore, a developer can restrict results to videos uploaded through the developer's own app or website but not to videos uploaded through other apps or sites.
  The new feature offers functionality that is similar, albeit not identical, to the developer tags functionality that the v2 API supported.
- The channel resource's new snippet.country property lets channel owners associate their channels with a particular country.
  Note: To set the snippet.country property for a channel resource, you actually need to update the brandingSettings.channel.country property.
- The API now supports targeting for channelSection resources. Channel section targeting provides a way to restrict visibility of a content section to users that match particular criteria.
  The API exposes three targeting options. A user must meet all of the targeting settings for a channel section to be visible.
  - targeting.languages[] : A list of YouTube application languages . Users who have chosen one of those languages can see the corresponding channel section.
  - targeting.regions[] : A list of YouTube preferred content regions . The channel section is visible to users that have selected one of those regions as well as users for whom one of those regions is automatically selected.
  - targeting.countries[] : A list of countries where the channel section is visible. Each value in the list is an ISO 3166-1 alpha-2 country code .
- The definition of the video resource's contentDetails.duration property has been corrected to reflect that the value can reflect hours, days, and so forth.
- The documentation for the channelSections.delete , playlistItems.delete , playlists.delete , subscriptions.delete , and videos.delete method has been corrected to reflect that, when successful, those methods all return an HTTP 204 response code ( No Content ).

New and updated errors

The API now supports the following errors:

نوع خطا	جزئیات خطا	شرح
`badRequest (400)`	`targetInvalidCountry`	The `channelSections.insert` and `channelSections.update` methods return this error if the inserted `channelSection` resource contained an invalid value for the `targeting.countries[]` property.

`badRequest (400)`	`operationNotSupported`	The `comments.insert` method returns this error if the API user is not able to insert a comment in reply to the top-level comment identified by the `snippet.parentId` property. In a `commentThread` resource, the `snippet.canReply` property indicates whether the current viewer can reply to the thread.
`badRequest (400)`	`invalidChannelId`	The `search.list` method returns this error if the `channelId` parameter in the request specified an invalid channel ID.
`badRequest (400)`	`subscriptionForbidden`	The `subscriptions.insert` method returns this error if the API user tries to subscribe to the user's own channel.

The captions.update method no longer supports the invalidMetadata and videoNotFound errors.

16 آوریل 2015

This update contains the following changes:

The migration guide has been updated to explain how to migrate applications still using comments functionality from the v2 API.
The guide also calls out several commenting features that the v2 API did not support but that are supported in the v3 API . این شامل:
- Retrieving comments about a channel
- Retrieving all comment threads related to a channel, which means that the API response can contain comments about the channel or any of its videos.
- Updating the text of a comment
- Marking a comment as spam
- Setting a comment's moderation status
The Subscribing to push notifications guide has been updated to reflect the fact that notifications are only pushed to the Google PubSubHubBub hub and not also to the Superfeedr hub as previously indicated.

9 آوریل 2015

This update contains the following changes:

The API's new commentThread and comment resources let you retrieve, insert, update, delete, and moderate comments.
- A commentThread resource contains information about a YouTube comment thread, which comprises a top-level comment and replies, if any exist, to that comment. A commentThread resource can represent comments about either a video or a channel.
  The top-level comment and the replies are actually comment resources that are nested inside the commentThread resource. It is important to note that the commentThread resource does not necessarily contain all replies to a comment, and you need to use the comments.list method if you want to retrieve all replies for a particular comment. In addition, some comments do not have replies.
  The API supports the following methods for commentThread resources:
  - commentThreads.list – Retrieve a list of comment threads. Use this method to retrieve comments associated with a particular video or channel.
  - commentThreads.insert – Create a new top-level comment. (Use the comments.insert method to reply to an existing comment.)
  - commentThreads.update – Modify a top-level comment.
- A comment resource contains information about a single YouTube comment. A comment resource can represent a comment about either a video or a channel. In addition, the comment could be a top-level comment or a reply to a top-level comment.
  The API supports the following methods for comment resources:
  - comments.list – Retrieve a list of comment. Use this method to retrieve all of the replies to a particular comment.
  - comments.insert – Create a reply to an existing comment.
  - comments.update – Modify a comment.
  - comments.markAsSpam – Flag one or more comments as spam.
  - comments.setModerationStatus – Set the moderation status of one or more comments. For example, clear a comment for public display or reject a comment as unfit for display. The API request must be authorized by the owner of the channel or video associated with the comments..
  - comments.delete – Delete a comment.
Note that the API's new https://www.googleapis.com/auth/youtube.force-ssl scope, described in the revision history for April 2, 2015 , is required for calls to the comments.insert , comments.update , comments.markAsSpam , comments.setModerationStatus , comments.delete , commentThreads.insert , and commentThreads.update methods.
The new Subscribing to push notifications guide explains the API's new support for push notifications via PubSubHubBub , a server-to-server publish/subscribe protocol for Web-accessible resources. Your PubSubHubBub callback server can receive Atom feed notifications when a channel does any of the following activities:
- uploads a video
- updates a video's title
- updates a video's description
The migration guide has also been updated to note the new support for push notifications. However, since the v2 API supported numerous other types of push notifications that are not supported in the v3 API, the mention of PubSubHubBub support is still listed in the Deprecated section of that guide.
The API's new https://www.googleapis.com/auth/youtube.force-ssl scope is now a valid scope for any API method that previously supported the https://www.googleapis.com/auth/youtube scope.
The API now supports the following errors:
نوع خطا جزئیات خطا شرح
badRequest (400) invalidRating The videos.rate method returns this error if the request contained an unexpected value for the rating parameter.
The subscriptions.insert method no longer supports the subscriptionLimitExceeded error, which previously indicated that the subscriber identified with the request had exceeded the subscription rate limit.

`badRequest (400)`	`invalidRating`	The `videos.rate` method returns this error if the request contained an unexpected value for the `rating` parameter.

2 آوریل 2015

This update contains the following changes:

The new captions resource represents a YouTube caption track. A caption track is associated with exactly one YouTube video.
The API supports methods to list , insert , update , download , and delete caption tracks.
The migration guide has also been updated to explain how to migrate applications still using captions functionality in the v2 API.
The API's new https://www.googleapis.com/auth/youtube.force-ssl scope requires communication with the API server to happen over an SSL connection.
This new scope grants the same access as the https://www.googleapis.com/auth/youtube scope. And, in fact, those two scopes are functionally identical because the YouTube API server is only available via an HTTPS endpoint. As a result, even though the https://www.googleapis.com/auth/youtube scope does not require an SSL connection, there is actually no other way to make an API request.
The new scope is required for calls to the all of the caption resource's methods.

11 مارس 2015

This update contains the following changes:

The YouTube Data API (v3) migration guide contains a new tab, named New in the v3 API , that lists features that the v3 API does support and that the v2 API did not support. The same features were previously and are still listed in other tabs in the guide. For example, the new feature explaining how to update a channel's in-video promotional campaign data is also listed under the Channels (profiles) tab.
The YouTube Data API (v3) migration guide has been updated to note that the v3 API will support the following v2 API feature:
- Flagging a video
The YouTube Data API (v3) migration guide has been updated to note that the following v2 API features will not be supported in the v3 API:
- Retrieve video recommendations – The v3 API does not retrieve a list that only contains videos recommended for the current API user. However, you can use the v3 API to find recommended videos by calling the activities.list method and setting the home parameter value to true .
  In the API response, a resource corresponds to a recommended video if the snippet.type property's value is recommendation . In that case, the contentDetails.recommendation.reason and contentDetails.recommendation.seedResourceId properties will contain information about why the video was recommended. Note that there is no guarantee that the response will contain any particular number of recommended videos.
- Retrieve channel suggestions
- Retrieve new subscription videos – The v3 API does not retrieve a list that only contains videos that have recently been uploaded to channels that the API user subscribes to. However, you can use the v3 API to find new subscription videos by calling the activities.list method and setting the home parameter value to true .
  In the API response, a resource corresponds to a new subscription video if the snippet.type property's value is upload . Note that there is no guarantee that the response will contain any particular number of new subscription videos.
- RSS feed support
- Push notifications for feed updates – The v2 API supported push notifications, using either the Simple Update Protocol (SUP) or PubSubHubbub , to monitor user activity feeds for YouTube users. Notifications were provided for new channel subscriptions and when videos were rated, shared, marked as favorites, commented on, or uploaded.
  The v3 API will support push notifications using the PubSubHubbub protocol , but the notifications will only cover video uploads and updates to video titles or video descriptions.
- Channel location – The v2 API used the <yt:location> tag to identify the user's location as entered in the channel's YouTube public profile. While some developers used this field to associate a channel with a particular country, the field's data could not consistently be used for that purpose.
- Set or retrieve developer tags – The v2 API supported the ability to associate keywords, or developer tags, with a video at the time that the video was uploaded. Developer tags would not be displayed to YouTube users, but video owners could retrieve videos that matched a specific developer tag.
  The v3 API will provide a similar, but not identical, feature. Specifically, a developer will be able to search for videos uploaded by the developer's own application. For this feature, each uploaded video is automatically tagged with the project number that is associated with the developer's application in the Google Developers Console . The developer then uses the same project number to search for videos.
- List videos by publication date, viewcount, or rating – In the v2 API, the orderby parameter let you sort videos in a playlist by position, duration, publication date, title, and several other values. In the v3 API, playlist items are typically sorted by position in ascending order and other sorting options are not available.
  چند استثنا وجود دارد. A new upload, favorite video, liked video, or recently watched video is automatically added as the first item ( snippet.position = 0 ) for the following types of playlists. So, each of these lists is effectively sorted in order of newest to oldest item based on the times that items were added to the list.
  - user uploads
  - ویدیوهای مورد علاقه
  - liked videos
  - watch history
  Note, however, that a new item added to the "Watch later" playlist is added as the last item in that list, so that list is effectively sorted from oldest to newest item.
- Batch processing – The v3 API supports one of the batch processing use cases that the v2 API had supported. The v3 API's channels.list , channelSections.list , guideCategories.list , playlistItems.list , playlists.list , subscriptions.list , videoCategories.list , and videos.list methods all support an id parameter, which can be used to specify a comma-delimited list of IDs (video IDs, channel IDs, etc.). Using those methods, you can retrieve a list of multiple resources with a single request.
With these changes, the guide now identifies all functionality that was supported in the old (v2) API that will be deprecated in the current API version (v3).

4 مارس 2015

This update contains the following changes:

The channelSections.delete and channelSections.update methods now support the onBehalfOfContentOwner parameter, which is already supported for several other methods.
The following properties and their child properties have been deprecated:
- brandingSettings.image.backgroundImageUrl
- brandingSettings.image.largeBrandedBannerImageImapScript
- brandingSettings.image.largeBrandedBannerImageUrl
- brandingSettings.image.smallBrandedBannerImageImapScript
- brandingSettings.image.smallBrandedBannerImageUrl
Note: None of these properties had been subject to the API Deprecation Policy.
The video resource's new contentDetails.contentRating.contentDetails.contentRating.djctqRatingReasons property identifies the reasons that explain why the video received its DJCQT (Brazil) rating.

The API now supports the following errors:

نوع خطا	جزئیات خطا	شرح
`notFound (404)`	`channelNotFound`	The `channels.update` method returns this error if the request's `id` parameter specifies a channel that cannot be found.
`badRequest (400)`	`manualSortRequiredinvalidValue`	The `playlistItems.insert` and `playlistItems.update` methods return this error if the request attempts to set the playlist item's position, but the playlist does not use manual sorting. For example, playlist items might be sorted by date or popularity. You can address this error by removing the `snippet.position` element from the resource sent in the request body. If you want the playlist item to have a specific position in the list, you need to first update the playlist's ordering setting to Manual . THis setting can be adjusted in the YouTube Video Manager .
`forbidden (403)`	`channelClosed`	The `playlists.list` method returns this error if the request's `channelId` parameter specifies a channel that has been closed.
`forbidden (403)`	`channelSuspended`	The `playlists.list` method returns this error if the request's `channelId` parameter specifies a channel that has been suspended.
`forbidden (403)`	`playlistForbidden`	The `playlists.list` method returns this error if the request's `id` parameter does not support the request or the request is not properly authorized.
`notFound (404)`	`channelNotFound`	The `playlists.list` method returns this error if the request's `channelId` parameter specifies a channel that cannot be found.
`notFound (404)`	`playlistNotFound`	The `playlists.list` method returns this error if the request's `id` parameter specifies a playlist that cannot be found.
`notFound (404)`	`videoNotFound`	The `videos.list` method returns this error if the request's `id` parameter specifies a video that cannot be found.
`badRequest (400)`	`invalidRating`	The `videos.rate` method returns this error if the request contains an unexpected value for the `rating` parameter.

This update contains the following changes:

The search.list method now supports the relevanceLanguage parameter, which lets you request results that are most relevant to a particular language.
The YouTube Data API (v3) migration guide has also been updated to explain how to use this new parameter. The parameter addresses a feature gap that previously existed between the current API version (v3) and the previous version (v2), which has already been deprecated.
The YouTube Data API (v3) migration guide has also been updated to indicate the deprecation of the special feeds and metadata fields that the v2 API provided for describing movies, trailers, television shows, television seasons, and television episodes.

14 ژانویه 2015

This update contains the following changes:

The YouTube Data API (v3) migration guide has been updated to explain how to use the v3 API to upload videos using JavaScript. (See the Upload a video section for details.) This functionality is comparable to the browser-based uploading functionality that the v2 API supports. Note that this change to the migration guide does not reflect an actual API change but rather the availability of new sample code for uploading videos with client-side JavaScript.
Given the support for uploading videos with the JavaScript client library and CORS, the migration guide no longer lists browser-based uploading as a feature that may be deprecated in the v3 API.
The documentation for the videos.insert method has been updated to include the new JavaScript code sample described above. The list of JavaScript code samples for the YouTube Data API (v3) has also been updated.

November 11, 2014

This update contains the following changes:

The quota cost for a call to the search.list method has changed to 100 units.
Important: In many cases, you can use other API methods to retrieve information at a lower quota cost. For example, consider these two ways of finding videos uploaded to the GoogleDevelopers channel.
- Quota cost: 100 units
  Call the search.list method and search for GoogleDevelopers .
- Quota cost: 6 units
  Call the channels.list method to find the right channel ID. Set the forUsername parameter to GoogleDevelopers and the part parameter to contentDetails . In the API response, the contentDetails.relatedPlaylists.uploads property specifies the playlist ID for the channel's uploaded videos.
  Then call the playlistItems.list method and set the playlistId parameter to the captured ID and the part parameter to snippet .

8 اکتبر 2014

This update contains the following changes:

The channel resource contains two new properties:
- The status.longUploadsStatus property indicates whether the channel is eligible to upload videos that are more than 15 minutes long. This property is only returned if the channel owner authorized the API request. Valid property values are:
  - allowed – The channel can upload videos more than 15 minutes long.
  - eligible – The channel is eligible to upload videos more than 15 minutes long but must first enable the feature.
  - disallowed – The channel is not able or eligible to upload videos more than 15 minutes long.
  See the property definition for more information about these values. The YouTube Help Center also provides more detailed information about this feature.
- The invideoPromotion.useSmartTiming property indicates whether the channel's promotional campaign uses "smart timing." This feature attempts to show promotions at a point in the video when they are more likely to be clicked and less likely to disrupt the viewing experience. This feature also picks up a single promotion to show on each video.
The definitions of the video resource's snippet.title and snippet.categoryId properties have both been updated to clarify the way that API handles calls to the videos.update method. If you call that method to update the snippet part of a video resource, you must set a value for both of those properties.
If you try to update the snippet part of a video resource and do not set a value for both of those properties, the API returns an invalidRequest error. That error's description has also been updated.
The video resource's contentDetails.contentRating.oflcRating property, which identifies a video's rating from New Zealand's Office of Film and Literature Classification, now supports two new ratings: oflcRp13 and oflcRp16 . These correspond to the RP13 and RP16 ratings, respectively.

The channelBanners.insert method now supports the following error:

نوع خطا	جزئیات خطا	شرح
`badRequest`	`bannerAlbumFull`	The channel owner's YouTube Channel Art album has too many images. The channel owner should go to http://photos.google.com , navigate to the albums page, and remove some from images from that album.

This update contains the following changes:

A new guide, titled Migrating Your Application to YouTube Data API (v3) , explains how to use the YouTube Data API (v3) to perform functionality available in the YouTube Data API (v2). The older API was officially deprecated as of March 4, 2014. The guide intends to help you migrate applications still using the v2 API to the most recent API version.

This update contains the following changes:

The playlists.insert method now supports the following error:
نوع خطا جزئیات خطا شرح
badRequest maxPlaylistExceeded This error occurs if a playlist cannot be created because the channel already has the maximum number of playlists allowed.

نوع خطا	جزئیات خطا	شرح
`badRequest`	`maxPlaylistExceeded`	This error occurs if a playlist cannot be created because the channel already has the maximum number of playlists allowed.

18 ژوئن 2014

This update contains the following changes:

The description of each API method has been updated to include the quota cost incurred by a call to that method. Similarly, the definitions of part parameters have been updated to specify the quota cost of each part that can be retrieved in an API call. For example, a call to the subscriptions.insert method has a quota cost of approximately 50 units. The subscription resource also contains three parts ( snippet , contentDetails , and subscriberSnippet ), and each of those has a cost of two units.
Please remember that quota costs can change without warning.
The video resource now supports 43 new content rating systems, which identify the ratings that videos received from various national rating agencies. The newly supported rating systems are from Argentina , Austria , Belgium , Bulgaria , Chile ( television ), Chile ( film ), Czech Republic , Colombia , Denmark , Egypt , Estonia , Finland , France , Greece , Hong Kong , Iceland , Indonesia , Ireland , Israel , Italy , Kenya , Latvia , Luxembourg , Malaysia , Maldives , Malta , Netherlands , Nigeria , Norway , Peru , Philippines , Portugal , Romania , Singapore , Slovakia , South Africa , Sweden , Switzerland , Taiwan , Thailand , and Venezuela .

28 مه 2014

This update contains the following changes:

The search.list method now supports the location and locationRadius parameters, which let you search for videos associated with a geographic location. A request must specify a value for both parameters to retrieve results based on location, and the API will return an error if a request includes only one of the two parameters.
- The location parameter specifies the latitude/longitude coordinates at the center of the circular geographic area.
- The locationRadius parameter specifies the maximum distance that the location associated with a video can be from the center of the area for the video to still be included in search results.

13 مه 2014

This update contains the following changes:

The channel resource's invideoPromotion.items[] property has been updated to note that you can typically only set one promoted item for your channel. If you try to insert too many promoted items, the API will return a tooManyPromotedItems error, which has an HTTP 400 status code.
The channelSection resource now can contain information about a few new types of featured content. The channelSection resource's snippet.type property now supports the following values:
- postedPlaylists - playlists that the channel's owner posted to the channel's activity feed
- postedVideos - videos that the channel's owner posted to the channel's activity feed
- subscriptions - channels that the channel owner has subscribed to
The video resource's new contentDetails.contentRating.ifcoRating property identifies the rating that a video received from the Irish Film Classification Office.
The definition of the watermark resource's position.cornerPosition property has been updated to note that the watermark always appear in the upper right corner of the player.
The definition of the q parameter for the search.list method has been updated to note that the query term can use the Boolean NOT ( - ) operator to exclude videos associated with a particular search term. The value can also use the Boolean OR ( | ) operator to find videos associated with one of several search terms.
The definition of the pageInfo.totalResults property that is returned in an API response to a search.list call has been updated to note that the value is an approximation and may not represent an exact value. In addition, the maximum value is 1,000,000. You should not use this value to create pagination links. Instead, use the nextPageToken and prevPageToken property values to determine whether to show pagination links.
The watermarks.set and watermarks.unset methods have been updated to reflect that the API returns an HTTP 204 response code for successful requests to those methods.

2 مه 2014

This update contains the following changes:

The new i18nLanguage resource identifies an application language that the YouTube website supports. The application language can also be referred to as a UI language. For the YouTube website, an application language could be automatically selected based on Google Account settings, browser language, or IP location, and a user could also manually select the desired UI language from the YouTube site footer.
The API supports a method to list supported application languages. Supported languages can be used as the value of the hl parameter when calling API methods like videoCategories.list and guideCategories.list .
The new i18nRegion resource identifies a geographic area that a YouTube user can select as the preferred content region. The content region can also be referred to as a content locale. For the YouTube website, a content region could be automatically selected based on heuristics like the YouTube domain or the user's IP location, and a user could also manually select the desired content region from the YouTube site footer.
The API supports a method to list supported content regions. Supported region codes can be used as the value of the regionCode parameter when calling API methods like search.list , videos.list , activities.list , and videoCategories.list .

7 آوریل 2014

This update contains the following changes:

The new channelSection resource contains information about a set of videos that a channel has chosen to feature. For example, a section could feature a channel's latest uploads, most popular uploads, or videos from one or more playlists.
The API supports methods to list , insert , update , or delete channel sections. You can retrieve a list of channel sections for the authenticated user's channel, by specifying a particular channel ID, or by specifying a list of unique channel section IDs.
The error documentation has also been updated to describe the error messages that the API supports specifically for these new methods.
The definition of the video resource's fileDetails object has been updated to explain that that object will only be returned if the video's processingDetails.fileDetailsAvailability property has a value of available .
Similarly, the definition of the video resource's suggestions object has been updated to explain that that object will only be returned if the video's processingDetails.tagSuggestionsAvailability property or its processingDetails.editorSuggestionsAvailability property has a value of available .
The documentation for the videos.insert and videos.update methods has been updated to reflect that the status.publishAt property can be set when calling those methods.
The definition of the channel resource's invideoPromotion object has been updated to explain that the object can only be retrieved by the channel's owner.
The parameter list for the videos.rate method has been updated to reflect that that method does not actually support the onBehalfOfContentOwner parameter. This was a documentation error as videos.rate requests that set this parameter return a 500 error.

31 مارس 2014

This update contains the following changes:

The video resource's new status.publishAt property lets you specify the date and time when a private video is scheduled to be published. This property can only be set if the video's privacy status is private and the video has never been published. This new property is not subject to the deprecation policy .

13 مارس 2014

This update contains the following changes:

The API now supports the contentOwnerDetails part for channel resources. The new part contains channel data that is relevant for YouTube partners linked with the channel, including the ID of the content owner linked to the channel and the date and time when the content owner and channel were linked. Note that this new part is not subject to the deprecation policy .

The documentation now lists the maximum supported character length for the following properties:

`channel`	`invideoPromotion.items[].customMessage`	40 characters
`video`	`snippet.title`	100 characters
`video`	`snippet.description`	5000 bytes
`video`	`snippet.tags`	500 characters. Note that the property value is a list and that commas between items in the list count toward the limit.

The channel resource's brandingSettings.watch.featuredPlaylistId property has been deprecated. The API will return an error if you attempt to set its value.
The following video resource properties have been added to the list of values that can be set when inserting or updating a video:
The error documentation now specifies the HTTP response code for each error type.

The API now supports the following errors:

نوع خطا	جزئیات خطا	شرح
`badRequest (400)`	`invalidCriteria`	The `channels.list` method returns this error if the request specifies filter parameters that cannot be used in conjunction with each other.
`badRequest (400)`	`channelTitleUpdateForbidden`	The `channels.update` method returns this error if you attempt to update a channel's `brandingSettings` part and change the value of the `brandingSettings.channel.title` property. (Note that the API does not return the error if you omit the property.)
`badRequest (400)`	`invalidRecentlyUploadedBy`	The `channels.update` method returns this error if the `invideoPromotion.items[].id.recentlyUploadedBy` property specifies an invalid channel ID.
`badRequest (400)`	`invalidTimingOffset`	The `channels.update` method returns this error if the `invideoPromotion` part specifies an invalid timing offset.
`badRequest (400)`	`tooManyPromotedItems`	The `channels.update` method returns this error if the `invideoPromotion` part specifies more than the allowed number of promoted items.
`forbidden (403)`	`promotedVideoNotAllowed`	The `channels.update` method returns this error if the `invideoPromotion.items[].id.videoId` property specifies a video ID that either cannot be found or cannot be used as a promoted item.

The YouTube Data API, v3 is now subject to the Deprecation Policy described in the YouTube APIs Terms of Service . Note that the page that lists the APIs that are subject to the deprecation policy specifically excludes some v3 API functionality from being subject to the policy.

5 دسامبر 2013

This update contains the following changes:

The search.list method's documentation has been updated to properly reflect that you do not need to specify a value for exactly one filter parameter when submitting a search request. Rather, you can set a value for zero filter parameters or for one filter parameter.
The definitions for the search.list method's parameters have been updated to note that you must set the type parameter's value to video if you also specify a value for any of the following parameters:
- eventType
- videoCaption
- videoCategoryId
- videoDefinition
- videoDimension
- videoDuration
- videoEmbeddable
- videoLicense
- videoSyndicated
- videoType
The minimum size of uploaded channel banner images has been reduced to 2048px by 1152px. (Previously, the minimum size was 2120px by 1192px.) In addition, note that the channel resource documentation specifies the maximum sizes of all of the banner images served from the API. For example, the maximum size of the brandingSettings.image.bannerTvImageUrl image for television applications is 2120px by 1192px, but the actual image may be 2048px by 1152px. The YouTube Help Center provides additional guidance for optimizing channel art for display on different types of devices.
Several channel resource property definitions have been updated to reflect the following information:
- The brandingSettings.channel.description property's value has a maximum length of 1000 characters.
- The brandingSettings.channel.featuredChannelsTitle property has a maximum length of 30 characters.
- The brandingSettings.channel.featuredChannelsUrls[] property can now list up to 100 channels.
- The brandingSettings.channel.unsubscribedTrailer property value, if set, must specify the YouTube video ID of a public or unlisted video that is owned by the channel owner.
The channels.update method now supports updates to the invideoPromotion.items[].promotedByContentOwner property. That property indicates whether the content owner's name will be shown when displaying the promotion. It can only be set if the API request that sets the property value is being made on the content owner's behalf using the onBehalfOfContentOwner parameter.
The playlistItems.list and playlistItems.insert methods now support the onBehalfOfContentOwner parameter, which is already supported for several other methods.
The contentDetails.contentRating.acbRating property can now specify a rating from either the Australian Classification Board (ACB) for movies or from the Australian Communications and Media Authority (ACMA) for children's television programming.
The new contentDetails.contentRating.catvRating and contentDetails.contentRating.catvfrRating properties identify the ratings that a video received under the Canadian TV Classification System and the French-language Régie du cinéma rating system, which is used in Québec, respectively.
The videoCategory resource's new snippet.assignable property indicates whether updated videos or newly uploaded videos can be associated with that video category.
Code samples have been added for the following methods:
- activities.insert (Go)
- channelBanners.insert (Python)
- channels.update (Python)
- playlistItems.list (Go)
- search.list (Go)
- thumbnails.set (Java)
- videos.insert (Go)

24 اکتبر 2013

This update contains the following changes:

The API includes two additional features designed to help find and feature live broadcast content:
The new snippet.liveBroadcastContent property in search results indicates whether a video or channel resource has live broadcast content. Valid property values are upcoming , active , and none .
- The video resource's new snippet.liveBroadcastContent property indicates whether the video is an upcoming or active live broadcast. The list below explains the property's possible values:
  - upcoming – The video is a live broadcast that has not yet started.
  - active – The video is an ongoing live broadcast.
  - none – The video is not an upcoming or active live broadcast. This will be the property value for completed broadcasts that are still viewable on YouTube.
- The video resource's new liveStreamingDetails property is an object that contains metadata about a live video broadcast. To retrieve this metadata, include liveStreamingDetails in the part parameter value's list of resource parts. The metadata includes the following new properties:
  - liveStreamingDetails.actualStartTime – The time that the broadcast actually started. (This value will be present once the broadcast's state is active .)
  - liveStreamingDetails.actualEndTime – The time that the broadcast actually ended. (This value will be present once the broadcast is over.)
  - liveStreamingDetails.scheduledStartTime – The time that the broadcast is scheduled to begin.
  - liveStreamingDetails.scheduledEndTime – The time that the broadcast is scheduled to end. If the property value is empty or the property is not present, then the broadcast is scheduled to go on indefinitely.
  - liveStreamingDetails.concurrentViewers – The number of people watching the live broadcast.
  To retrieve this metadata, include liveStreamingDetails in the part parameter value when calling the videos.list , videos.insert , or videos.update method.
Note that two other features for identifying live broadcast content were released on October 1, 2013 – the search.list method's eventType parameter and the search result's snippet.liveBroadcastContent property.
The videos.insert method now supports the notifySubscribers parameter, which indicates whether YouTube should send a notification about the new video to users who subscribe to the video's channel. The parameter's default value is True , which indicates that subscribers will be notified of newly uploaded videos. However, a channel owner who is uploading many videos might prefer to set the value to False to avoid sending a notification about each new video to the channel's subscribers.
The list of properties that can be modified when calling the channels.update method has been updated to include the invideoPromotion.items[].customMessage and invideoPromotion.items[].websiteUrl properties. In addition, the list has been modified to identify the brandingSettings properties that are modifiable. These brandingSettings properties were already modifiable, so the documentation change does not reflect a change to the API's existing functionality.
The playlists.insert , playlists.update , and playlists.delete methods now support the onBehalfOfContentOwner parameter, which is already supported for several other methods.
The playlists.insert method now supports the onBehalfOfContentOwnerChannel parameter, which is already supported for several other methods.
The video resource's contentDetails.contentRating.tvpgRating property now supports a value of pg14 , which corresponds to a TV-14 rating.
The definition of the snippet.liveBroadcastContent property, which is part of search results, has been corrected to reflect that live is a valid property value, but active is not a valid property value.
The video resource's contentDetails.contentRating.mibacRating property now supports two additional ratings:
- mibacVap (VAP) – Children should be accompanied by an adult.
- mibacVm6 (VM6) – Restricted to 6 and over.
- mibacVm12 (VM12) – Restricted to 12 and over.
The channel resource's new invideoPromotion.items[].promotedByContentOwner property indicates whether the content owner's name will be shown when displaying the promotion. This field can only be set if the API request that sets the value is being made on the content owner's behalf. See the onBehalfOfContentOwner parameter for more information.

1 اکتبر 2013

This update contains the following changes:

The channel resource's new auditDetails object contains channel data that a multichannel network (MCN) would evaluate while determining whether to accept or reject a particular channel. Note that any API request that retrieves this resource part must provide an authorization token that contains the https://www.googleapis.com/auth/youtubepartner-channel-audit scope. In addition, any token that uses that scope must be revoked when the MCN decides to accept or reject the channel or within two weeks of the date that the token was issued.
The channel resource's invideoPromotion.items[].id.type property now supports a value of recentUpload , which indicates that the promoted item is the most recently uploaded video from a specified channel.
By default, the channel is the same as the one for which the in-video promotion data is set. However, you can promote the most recently uploaded video from another channel by setting the value of the new invideoPromotion.items[].id.recentlyUploadedBy property to the channel ID for that channel.
The channel resource contains three new properties – brandingSettings.image.bannerTvLowImageUrl , brandingSettings.image.bannerTvMediumImageUrl , brandingSettings.image.bannerTvHighImageUrl – that specify the URLs for the banner images that display on channel pages in television applications.
The new snippet.liveBroadcastContent property in search results indicates whether a video or channel resource has live broadcast content. Valid property values are upcoming , active , and none .
- For a video resource, a value of upcoming indicates that the video is a live broadcast that has not yet started, while a value of active indicates that the video is an ongoing live broadcast.
- For a channel resource, a value of upcoming indicates that the channel has a scheduled broadcast that has not yet started, while a value of acive indicates that the channel has an ongoing live broadcast.
In the watermark resource, the targetChannelId property has changed from an object to a string. Instead of containing a child property that specifies the YouTube channel ID of the channel that the watermark image links to, the targetChannelId property now specifies that value itself. Accordingly, the resource's targetChannelId.value property has been removed.
The thumbnails.set method now supports the onBehalfOfContentOwner parameter, which is already supported for several other methods.
The search.list method now supports the eventType parameter, which restricts a search to only return either active, upcoming, or completed broadcast events.
The new contentDetails.contentRating.mibacRating property identifies the rating that a video received from Italy's Ministero dei Beni e delle Attivita Culturali e del Turismo.

The API now supports the following errors:

نوع خطا	جزئیات خطا	شرح
`badRequest`	`invalidImage`	The `thumbnails.set` method returns this error if the provided image content is invalid.
`forbidden`	`videoRatingDisabled`	The `videos.rate` method returns this error if the owner of the video that is being rated has disabled ratings for that video.

August 27, 2013

This update contains the following changes:

The new watermark resource identifies an image that displays during playbacks of a specified channel's videos. You can also specify a target channel to which the image will link as well as timing details that determine when the watermark appears during video playbacks and the length of time it is visible.
The watermarks.set method uploads and sets a channel's watermark image. The watermarks.unset method deletes a channel's watermark image.
The error documentation describes the error messages that the API supports specifically for the watermarks.set and watermarks.unset methods.
The channel resource's new statistics.hiddenSubscriberCount property contains a boolean value that indicates whether the channel's number of subscribers is hidden. As such, the property's value is false if the channel's subscriber count is publicly visible.
The playlists.list method now supports the onBehalfOfContentOwner and onBehalfOfContentOwnerChannel parameters. Both parameters are already supported for several other methods.
The videos.list method now supports the regionCode parameter, which identifies the content region for which a chart should be retrieved. This parameter can only be used in conjunction with the chart parameter. The parameter value is an ISO 3166-1 alpha-2 country code.
The error documentation describes the following new common request error, which could occur for multiple API methods:
نوع خطا جزئیات خطا شرح
forbidden insufficientPermissions The scopes associated with the OAuth 2.0 token provided for the request are insufficient for accessing the requested data.

نوع خطا	جزئیات خطا	شرح
`forbidden`	`insufficientPermissions`	The scopes associated with the OAuth 2.0 token provided for the request are insufficient for accessing the requested data.

15 آگوست 2013

This update contains the following changes:

The channel resource's invideoPromotion object has the following new and updated properties:
- The API now supports the ability to specify a website as a promoted item. To do so, set the invideoPromotion.items[].id.type property value to website and use the new invideoPromotion.items[].id.websiteUrl property to specify the URL. Also use the new invideoPromotion.items[].customMessage property to define a custom message to display for the promotion.
  Links can be to associated websites, merchant sites, or social networking sites. See the YouTube Help Center instructions for associated websites and merchant sites for more information about enabling links for your content.
  By adding promotional links, you agree that those links will not be used to redirect traffic to unauthorized sites and that those links will comply with YouTube's AdWords policies , YouTube ad policies , YouTube Community Guidelines and YouTube Terms of Service .
- The properties related to the timing settings for displaying promoted items during video playback have been restructured:
  - The invideoPromotion.timing object has been moved to invideoPromotion.items[].timing . This object now enables you to customize the timing data for each promoted item in the invideoPromotion.items[] list.
  - The new invideoPromotion.defaultTiming object specifies default timing settings for your promotion. Those settings define when a promoted item will display during playback of one of your channel's videos. You can override the default timing for any given promoted item using the invideoPromotion.items[].timing object.
  - The new invideoPromotion.items[].timing.durationMs property specifies the amount of time, in milliseconds, that the promotion should display. The invideoPromotion.defaultTiming object also contains a durationMs field that specifies the default amount of time that the promoted item will display.
- The invideoPromotion.items[].type and invideoPromotion.items[].videoId properties both have been moved into the invideoPromotion.items[].id object.
The subscriptions.list method now supports the onBehalfOfContentOwner and onBehalfOfContentOwnerChannel parameters. Both parameters are already supported for several other methods.
In the API response to a thumbnails.set request, the kind property value has changed from youtube#thumbnailListResponse to youtube#thumbnailSetResponse .
Code samples have been added for the following methods:
- channels.update (Java, Python)
- playlists.insert (.NET, PHP)
- subscriptions.insert (PHP, Python)
- thumbnails.set (PHP, Python)
- videos.insert (PHP)
- videos.list (PHP)
- videos.rate (Python)
- videos.update (Java, PHP, Python)
Note that the Python example for the playlistItems.insert method was also removed since the functionality it demonstrated is now handled by the videos.rate method.

The error documentation describes the following new request context error, which could occur for any API method that supports the mine request parameter:

نوع خطا	جزئیات خطا	شرح
`badRequest`	`invalidMine`	The `mine` parameter cannot be used in requests where the authenticated user is a YouTube partner. You should either remove the `mine` parameter, authenticate as a YouTube user by removing the `onBehalfOfContentOwner` parameter, or act as one of the partner's channels by providing the `onBehalfOfContentOwnerChannel` parameter if available for the called method.

In a channelBanner resource, the value of the kind property's value has changed from youtube#channelBannerInsertResponse to youtube#channelBannerResource . This resource is returned in response to a channelBanners.insert request.
The channel resource's new brandingSettings.channel.profileColor property specifies a prominent color that complements the channel's content. The property value is a pound sign ( # ) followed by a six-character hexadecimal string, such as #2793e6 .
The API now supports the ability to specify whether a subscription is for all of a channel's activities or just for new uploads. The subscription resource's new contentDetails.activityType property identifies the types of activities that the subscriber will be notified about. Valid property values are all and uploads .
The videos.list method supports new parameters for retrieving a chart of the most popular videos on YouTube:
- The chart parameter identifies the chart that you want to retrieve. Currently, the only supported value is mostPopular . Note that the chart parameter is a filter parameter, which means it cannot be used in the same request as other filter parameters ( id and myRating ).
- The videoCategoryId parameter identifies the video category for which the chart should be retrieved. This parameter can only be used in conjunction with the chart parameter. By default, charts are not restricted to a particular category.
The video resource's new topicDetails.relevantTopicIds[] property provides a list of Freebase topic IDs that are relevant to the video or its content. The subjects of these topics may be mentioned in or appear in the video.
The video resource's recordingDetails.location.elevation property has been renamed to recordingDetails.location.altitude , and its fileDetails.recordingLocation.location.elevation property has been renamed to fileDetails.recordingLocation.location.altitude .
The video resource's contentDetails.contentRating object specifies the ratings that a video received under various rating schemes, including MPAA ratings, TVPG ratings, and so forth. For each rating system, the API now supports a rating value that indicates that the video has not been rated. Note that for MPAA ratings , an "unrated" rating is frequently used to identify uncut versions of films for which the cut version of the film did receive an official rating.
The video resource's new contentDetails.contentRating.ytRating property identifies age-restricted content. The property value will be ytAgeRestricted if YouTube has identified the video as containing content that is inappropriate for users less than 18 years old. If the property is absent or if the property value is empty, then the content has not been identified as age-restricted.
The channels.list method's mySubscribers parameter has been deprecated. Use the subscriptions.list method and its mySubscribers parameter to retrieve a list of subscribers to the authenticated user's channel.
The channelBanners.insert , channels.update , videos.getRating , and videos.rate methods all now support the onBehalfOfContentOwner parameter. That parameter indicates that the authenticated user is acting on behalf of the content owner specified in the parameter value.
The channels.update method's documentation has been updated to reflect the fact that that method can be used to update the channel resource's brandingSettings object and its child properties. The documentation also now lists the updated list of properties that you can set for the channel resource's invideoPromotion object.

The error documentation describes the following new errors:

نوع خطا	جزئیات خطا	شرح
`forbidden`	`accountDelegationForbidden`	This error is not specific to a particular API method. It indicates that the authenticated user is not authorized to act on behalf of the specified Google account.
`forbidden`	`authenticatedUserAccountClosed`	This error is not specific to a particular API method. It indicates that the authenticated user's YouTube account is closed. If the user is acting on behalf of another Google Account, then this error would indicate that that other account is closed.
`forbidden`	`authenticatedUserAccountSuspended`	This error is not specific to a particular API method. It indicates that the authenticated user's YouTube account is suspended. If the user is acting on behalf of another Google Account, then this error would indicate that that other account is suspended.
`forbidden`	`authenticatedUserNotChannel`	This error is not specific to a particular API method. It indicates that the API server cannot identify the channel associated with the API request. If the request is authorized and uses the `onBehalfOfContentOwner` parameter, you should also set the `onBehalfOfContentOwnerChannel` parameter.
`forbidden`	`cmsUserAccountNotFound`	This error is not specific to a particular API method. The CMS user is not allowed to act on behalf of the specified content owner.
`notFound`	`contentOwnerAccountNotFound`	This error is not specific to a particular API method. The specified content owner account was not found.
`badRequest`	`invalidPart`	This error is not specific to a particular API method. The request's `part` parameter specifies parts that cannot be written at the same time.
`badRequest`	`videoChartNotFound`	The `videos.list` method returns this error when the request specifies an unsupported or unavailable video chart.
`notFound`	`videoNotFound`	The `videos.update` method returns this error to indicate that the video you are trying to update cannot be found. Check the value of the `id` property in the request body to ensure it is correct.

10 ژوئن 2013

This update contains the following changes:

The channels.list method's new forUsername parameter enables you to retrieve information about a channel by specifying its YouTube username.
The activities.list method now supports the regionCode parameter, which instructs the API to return results relevant to the specified country. YouTube uses this value when the authorized user's previous activity on YouTube does not provide enough information to generate the activity feed.
Playlist resources now contain the snippet.tags property. The property will be only be returned to authorized users who are retrieving data about their own playlists. Authorized users can also set playlist tags when calling either the playlists.insert or playlists.update methods.
The onBehalfOfContentOwner parameter, which was previously supported for the channels.list and search.list methods, is now also supported for the videos.insert , videos.update , and videos.delete methods. Note that when this parameter is used in a call to the videos.insert method, the request must also specify a value for the new onBehalfOfContentOwnerChannel parameter, which identifies the channel to which the video will be added. The channel must be linked to the content owner that the onBehalfOfContentOwner parameter specifies.
The parameter indicates that the request's authorization credentials identify a YouTube CMS user who is acting on behalf of the content owner specified in the parameter value. The CMS account that the user authenticates with must be linked to the specified YouTube content owner.
This parameter is intended for content partners that own and manage many different YouTube channels. The parameter enables those partners to authenticate once and get access to all of their video and channel data, without having to provide authentication credentials for each individual channel.
Specifically in regard to this release, the parameter now enables a content partner to insert, update, or delete videos in any of the YouTube channels that the partner owns.

The error documentation describes the following new errors:

نوع خطا	جزئیات خطا	شرح
`forbidden`	`insufficientCapabilities`	This error is not specific to a particular API method. It indicates that the CMS user calling the API does not have sufficient permissions to perform the requested operation. This error is associated with the use of the `onBehalfOfContentOwner` parameter, which is supported for several API methods.
`unauthorized`	`authorizationRequired`	The `activities.list` method returns this error when the request uses the `home` parameter but is not properly authorized.

In the channels resource, the invideoPromotion.channelId property has been removed because the channel ID is already specified using the resource's id property.
The new Working with Channel IDs guide explains how the API uses channel IDs. The guide may be especially useful for developers migrating from the previous version of the API and who have applications that either request content for the default user or that rely on the notion that every YouTube channel has a unique username, which is no longer the case.

22 مه 2013

This update contains the following changes:

The new channelBanners.insert method enables you to upload a banner image that can subsequently be set as the banner image for a channel using the channel resource's new brandingSettings.image.bannerExternalUrl property.
The documentation for the channels.update method has been updated to list the properties that can be modified when calling the method.
The video resource documentation no longer lists unspecified as a valid property value for the suggestions.processingErrors[] , suggestions.processingHints[] , suggestions.processingWarnings[] , and suggestions.editorSuggestions[] properties.
The videos.list method's maxResults parameter now has a default value of 5 .
The error documentation now lists errors for the channelBanners.insert and subscriptions.list methods. It also lists several new errors for the channels.update method.

May 14, 2013

This update contains the following changes:

This update contains the following changes:

YouTube no longer identifies experimental API features and services. Instead, we now provide a list of YouTube APIs that are subject to the deprecation policy .

8 مه 2013

This update contains the following changes:

Channel resources now support the inVideoPromotion object, which encapsulates information about a promotional campaign associated with the channel. A channel can use an in-video promotional campaign to display thumbnail images for a promoted video within the video player during playbacks of the channel's videos.
You can retrieve this data by including invideoPromotion in the part parameter value in a channels.list request.
The new channels.update method can be used to update a channel's in-video promotional campaign data. Note that the method only supports updates to the invideoPromotion part of the channel resource and does not yet support updates to other parts of that resource.

2 مه 2013

This update contains the following changes:

Channel resources now support the status.isLinked property, which indicates whether the channel data identifies a user that is already linked to either a YouTube username or a Google+ account. A user that has one of these links already has a public YouTube identity, which is a prerequisite for several actions, such as uploading videos.
Subscription resources now support the subscriberSnippet part. That object encapsulates contains snippet data for the subscriber's channel.
The API now supports the videos.getRating method, which retrieves the ratings that the authenticated user gave to a list of one or more videos.
The videos.list method's new myRating parameter enables you to retrieve a list of videos that the authenticated user rated with a like or dislike rating.
The myRating parameter and the id parameter are both now considered filter parameters, which means that an API request must specify exactly one of the parameters. (Previously, the id parameter was a required parameter for this method.)
The method returns a forbidden error for requests that attempt to retrieve video rating information but are not properly authorized to do so.
With the introduction of the myRating parameter, the videos.list method has also been updated to support pagination. Note, however, that paging parameters are only supported for requests using the myRating parameter. (Paging parameters and information are not supported for requests that use the id parameter.)
- The maxResults parameter specifies the maximum number of videos that the API can return in the result set, and the pageToken parameter identifies a specific page in the result set that you want to retrieve.
- The youtube#videoListResponse resource, which is returned in response to a videos.list request, now contains the pageInfo object, which contains details like the total number of results and the number of results included in the current result set. The youtube#videoListResponse resource can also include nextPageToken and prevPageToken properties, each of which provides a token that could be used to retrieve a specific page in the result set.
The videos.insert method supports the following new parameters:
- autoLevels – Set this parameter value to true to instruct YouTube to automatically enhance the video's lighting and color.
- stabilize – Set this parameter value to true to instruct YouTube to adjust the video by removing shakiness resulting from camera motions.
The channelTitle property has been added to the snippet for the following resources:
- playlistItem – The property specifies the name of the channel that added the playlist item.
- playlist – The property specifies the name of the channel that created the playlist.
- subscription – The property specifies the name of the channel that is subscribed to.
Code samples have been added for the following methods:
- activities.insert (Ruby)
- playlistItems.list (.NET)
- search.list (.NET)
- subscriptions.insert (Java, Ruby)
- videos.insert (.NET, Ruby)
The subscriptions.list method's new mySubscribers parameter enables you to retrieve a list of the currently authenticated user's subscribers. This parameter can only be used in a properly authorized request.
Note: This functionality is intended to replace the mySubscribers parameter currently supported for the channels.list method. That parameter will be deprecated.
In a video resource, the property value unspecified is no longer a possible value for any of the following properties:
API requests that contain an unexpected parameter now return a badRequest error, and the reported reason for the error is unexpectedParameter .
The error that the playlistItems.insert method returns when the playlist already contains the maximum number of allowed items has been updated. The error is now reported as a forbidden error, and the error reason is playlistContainsMaximumNumberOfVideos .

19 آوریل 2013

This update contains the following changes:

The new videos.rate method lets a user set a like or dislike rating on a video or remove a rating from a video.
The error documentation has also been updated to list the errors that the API might return in response to a videos.rate method call.
Thumbnail images are now identified in the API documentation as a separate resource , and the new thumbnails.set method enables you to upload a custom video thumbnail to YouTube and set it for a video.
The error documentation has also been updated to list the errors that the API might return in response to a thumbnails.set method call.
Note that this change does not really affect existing resources that return thumbnail images. Thumbnail images are returned in those resources in the same way that they were previously, though the documentation does now list the names of the different thumbnail sizes that the API might return.
The channel resource's new brandingSettings part identifies settings, text, and images for the channel's channel page and video watch pages.
The playlistItem resource contains the following new properties:
- The new status object encapsulates status information about the playlist item, and the status.privacyStatus property identifies the playlist item's privacy status.

The video resource contains the following new properties:

The status.publicStatsViewable property indicates whether extended video statistics on the watch page are publicly viewable. By default, those statistics are viewable, and statistics like a video's viewcount and ratings will still be publicly visible even if this property's value is set to false . You can set this property's value when calling the videos.insert or videos.update method.

The contentDetails.contentRating object encapsulates ratings that the video received under various rating schemes. The list below identifies the supported rating systems and provides a link to the property associated with each rating system. The property definitions identify the supported rating values for each system.

The playlistItems.update method's documentation has been updated to reflect the fact that the snippet.resourceId property must be specified in the resource sent as the request body.
The search.list method now supports the following functionality:
- The new forMine parameter restricts a search to only retrieve the authenticated user's videos.
- The order parameter now supports the ability to sort results alphabetically by title ( order=title ) or by video count in descending order ( order=videoCount ).
- The new safeSearch parameter indicates whether search results should include restricted content.

The videos.insert method supports several new errors, which are listed in the table below:

نوع خطا	جزئیات خطا	شرح
`badRequest`	`invalidCategoryId`	The `snippet.categoryId` property specifies an invalid category ID. Use the `videoCategories.list` method to retrieve supported categories.
`badRequest`	`invalidRecordingDetails`	The `metadata specifies invalid recording details.`
`badRequest`	`invalidVideoGameRating`	The request metadata specifies an invalid video game rating.
`badRequest`	`invalidVideoMetadata`	The request metadata is invalid.

12 مارس 2013

This update contains the following changes:

The channelTitle property has been added to the snippet for the following resources:
- activity – The property specifies the name of the channel responsible for the activity.
- search – The property specifies the name of the channel associated with the resource that the search result identifies.
- video – The property specifies the name of the channel that uploaded the video.
The search.list method supports the following new parameters:
- The channelType parameter lets you restrict a search for channels to retrieve all channels or to retrieve only shows.
- The videoType parameter lets you restrict a search for videos to retrieve all videos or to retrieve only movies or only episodes of shows.
The definition of the video resource's recordingDetails part has been updated to note that the object will only be returned for a video if the video's geolocation data or recording time has been set.
The playlistItems.update method now returns an invalidSnippet error, which is returned if the API request does not specify a valid snippet.
Several API methods support new parameters that are intended exclusively for YouTube content partners. YouTube content partners include movie and television studios, record labels, and other content creators that make their content available on YouTube.
- پارامتر onBehalfOfContentOwner نشان می دهد که اعتبارنامه مجوز درخواست، کاربر YouTube CMS را شناسایی می کند که از طرف مالک محتوا مشخص شده در مقدار پارامتر عمل می کند. The CMS account that the user authenticates with must be linked to the specified YouTube content owner.
  This parameter is intended for content partners that own and manage many different YouTube channels. The parameter enables those partners to authenticate once and get access to all of their video and channel data, without having to provide authentication credentials for each individual channel.
  The channels.list , search.list , videos.delete , videos.list , and videos.update methods all support this parameter.
- The managedByMe parameter, which is supported by the channels.list method, instructs the API to return all channels owned by the content owner that the onBehalfOfContentOwner parameter specifies.
- The forContentOwner parameter, which is supported by the search.list method, instructs the API to restrict search results to only include resources that are owned by the content owner that the onBehalfOfContentOwner parameter specifies.

25 فوریه 2013

This update contains the following changes:

The API supports several new parts and properties for video resources:
- The new fileDetails , processingDetails , and suggestions parts provide information to video owners about their uploaded videos. This data is very useful in applications that enable video uploads and includes the following:
  - processing status and progress
  - errors or other issues encountered while processing a video
  - availability of thumbnail images
  - suggestions for improving video or metadata quality
  - details about the original file uploaded to YouTube
  All of these parts can only be retrieved by the video owner. The list below briefly describes the new parts, and the video resource documentation defines all of the properties that each part contains.
  - The fileDetails object contains information about the video file that was uploaded to YouTube, including the file's resolution, duration, audio and video codecs, stream bitrates, and more.
  - The processingProgress object contains information about YouTube's progress in processing the uploaded video file. The object's properties identify the current processing status and estimate the time remaining until YouTube finishes processing the video. This part also indicates whether different types of data or content, such as file details or thumbnail images, are available for the video.
    This object is designed to be polled so that the video uploader can track the progress that YouTube has made in processing the uploaded video file.
  - The suggestions object contains suggestions that identify opportunities to improve the video quality or the metadata for the uploaded video.
- The contentDetails part contains four new properties. These properties can be retrieved with unauthenticated requests.
  - dimension – Indicates whether the video is available in 2D or 3D.
  - definition – Indicates whether the video is available in standard or high definition.
  - caption – Indicates whether captions are available for the video.
  - licensedContent – Indicates whether the video contains content that has been claimed by a YouTube content partner.
- The status part contains two new properties. Video owners can set values for both properties when inserting or updating a video. These properties can also be retrieved with unauthenticated requests.
  - embeddable – Indicates whether the video can be embedded on another website.
  - license – Specifies the video's license. Valid values are creativeCommon and youtube .
The definition of the part parameter has been updated for the videos.list , videos.insert , and videos.update methods to list the newly added parts described above as well as the recordingDetails part, which had been inadvertently omitted.
The channel resource's new contentDetails.googlePlusUserId property specifies the Google+ profile ID associated with the channel. This value can be used to generate a link to the Google+ profile.
Each thumbnail image object now specifies the image's width and height. Thumbnail images are currently returned in activity , channel , playlist , playlistItem , search result , subscription , and video resources.
The playlistItems.list now supports the videoId parameter, which can be used in conjunction with the playlistId parameter to only retrieve the playlist item that represents the specified video.
The API returns a notFound error if the video that the parameter identifies cannot be found in the playlist.
The error documentation describes a new forbidden error, which indicates that a request is not properly authorized for the requested action.
The channel resource's snippet.channelId property has been removed. The resource's id property provides the same value.

September 12, 2023

Note: This is a deprecation announcement.

The comments.markAsSpam method has been deprecated for several years. This method is already unsupported on YouTube and is no longer supported through the API.

A deprecation notice has been added to all of the documents referencing the comments.markAsSpam method.

22 اوت 2023

The search.list method now supports the videoPaidProductPlacement parameter. This parameter enables you to filter search results to include only videos that the creator has denoted as having a paid promotion.

18 آگوست 2023

The definition of the video resource's liveStreamingDetails.concurrentViewers has been updated to note that the concurrent viewer counts that the YouTube Data API returns might differ from the processed, despammed concurrent viewer counts available through YouTube Analytics. The YouTube Help Center provides more information about live streaming metrics.

7 آگوست 2023

As announced on June 12, 2023 , the search.list method's relatedToVideoId parameter has been deprecated. That parameter is no longer supported, and references to the parameter have been removed from the API documentation.

June 28, 2023

The thumbnails.set method now supports the uploadRateLimitExceeded error, which indicates that the channel has uploaded too many thumbnails during the past 24 hours and should try again later.

12 ژوئن 2023

Note: This is a deprecation announcement.

The search.list method's relatedToVideoId parameter has been deprecated. YouTube will stop supporting the parameter as of August 7, 2023.

At this time, a deprecation notice has been added to the search.list method's documentation. This parameter will be fully removed from the search.list documentation on or after August 7, 2023.

August 22, 2022

Corrected type annotations for video.statistics fields to string from unsigned long.

5 آگوست 2022

YouTube has changed the way that caption IDs are generated and, as part of that change, is assigning new caption IDs to all caption tracks. This change might be a backward-incompatible change for applications that store caption_id values, though it will not affect applications that do not store caption_id values.

Between now and December 1, 2022, the captions.list , captions.update , captions.download , and and captions.delete methods will support both the old and new caption track IDs. However, on or after December 1, 2022, YouTube will stop supporting the old caption track IDs. At that time, calling any of those API methods with an old caption track ID will result in a captionNotFound error.

To prepare for this change, you should plan to fully replace all stored caption track data between now and December 1, 2022. This means that for any video for which you store caption track data, you should delete the currently stored data, then call the captions.list method to retrieve the current set of caption tracks for the video and store the data in the API response as you would normally.

12 جولای 2022

The YouTube API Services Terms of Service has been updated. Please see the YouTube API Services Terms of Service - Revision History for more information.

As announced on November 18, 2021 , in conjunction with changes to make video dislike counts private across the entire YouTube platform , the video resource's statistics.dislikeCount property is now private.

You can learn more about this change on YouTube's official blog .

18 نوامبر 2021

In conjunction with changes to make video dislike counts private across the entire YouTube platform , the video resource's statistics.dislikeCount property will be made private as of December 13, 2021. This means that the property will only be included in an API response from the videos.list endpoint if the API request was authenticated by the video owner.

The videos.rate endpoint is not affected by this change.

Developers who do not display dislike counts publicly and still need the dislike count for their API client can apply to be put on an allow list for an exemption. To apply for an exemption, you must complete this application form .

You can learn more about this change on YouTube's official blog .

2 ژوئیه 2021

Note: This is a deprecation announcement.

The commentThreads.update endpoint has been deprecated and is no longer supported. This endpoint duplicated functionality available through other API endpoints. Instead, you can call the comments.update

method and, if your code requires a commentThreads resource, make a secondary call to the commentThreads.list method.

All developers using YouTube's API Services must complete an API Compliance Audit in order to be granted more than the default quota allocation of 10,000 units. To date, both the compliance audit process and requests for additional quota unit allocations have been conducted by developers filling out and submitting the YouTube API Services - Audit and Quota Extension Form .

To clarify these processes and better meet the needs of developers using our API Services, we are adding three new forms and a guide to completing those forms:

Audited Developer Requests Form : Developers who have already passed an API Compliance Audit can fill out and submit this shorter form to request an allocated quota extension.
Appeals Form : Developers whose API projects have failed a compliance audit (or been denied a quota unit increase) can fill out and submit this form.
Change of Control Form : Developers, or any party operating an API client on a developer's behalf, who experience a change of control (for example, through a stock purchase or sale, merger or other form of corporate transaction) associated with an API project must fill out and submit this form. This enables YouTube's API team to update our records, audit the new API project's use case compliance, and validate the developer's current quota allocation.

Each new form will inform us of your intended usage of YouTube's API and enable us to better assist you.

More details are available in our new API Compliance Audits guide .

12 مه 2021

Note: This is a deprecation announcement.

This update covers the following API changes:

The channel resource's contentDetails.relatedPlaylists.favorites property has been deprecated. Favorite videos functionality has already been deprecated for several years as noted in the April 28, 2016 , revision history entry.
Prior to this update, the API would still create a new playlist if an API client attempted to add a video to a nonexistent favorites playlist. Going forward, the playlist will not be created in this case and the API will return an error. Attempts to modify favorites playlists by adding, modifying, or deleting items are also all deprecated per prior announcements and might start returning errors at any time.
The following channel resource properties have been deprecated. These properties are already unsupported in the YouTube Studio UI and on YouTube. As a result, they are also no longer supported via the API.
- brandingSettings.channel.defaultTab
- brandingSettings.channel.featuredChannelsTitle
- brandingSettings.channel.featuredChannelsUrls[]
- brandingSettings.channel.profileColor
- brandingSettings.channel.showBrowseView
- brandingSettings.channel.showRelatedChannels
All of the properties have been removed from the channel resource representation , and their definitions have been removed from the resource's property list . In addition, errors associated with these properties have been removed from the method-specific documentation.
The following channelSection resource properties have been deprecated. These properties are already unsupported in the YouTube Studio UI and on YouTube. As a result, they are also no longer supported via the API.
- snippet.style
- snippet.defaultLanguage
- snippet.localized.title
- localizations
- localizations.(key)
- localizations.(key).title
- targeting
- targeting.languages[]
- targeting.regions[]
- targeting.countries[]
In conjunction with this change, the channelSection.list method's hl parameter has also been deprecated since the features it supports are not supported.
All of the properties have been removed from the channelSection resource representation , and their definitions have been removed from the resource's property list . In addition, errors associated with these properties have been removed from the method-specific documentation.
For the channelSection resource's snippet.type property, the following values have been deprecated. These values are already unsupported on YouTube channel pages and, as a result, they are also no longer supported via the API.
- likedPlaylists
- likes
- postedPlaylists
- postedVideos
- recentActivity
- recentPosts
The playlist resource's snippet.tags[] property has been deprecated. This property is already unsupported on YouTube and, as a result, it is no longer supported via the API.

9 فوریه 2021

The playlistItem resource supports two new properties:

The snippet.videoOwnerChannelId property identifies the ID of the channel that uploaded the playlist video.
The snippet.videoOwnerChannelTitle property identifies the name of the channel that uploaded the playlist video.

28 ژانویه 2021

This update contains the following changes:

The playlistItems.delete , playlistItems.insert , playlistItems.list , playlistItems.update , playlists.delete , playlists.list , and playlists.update methods all support a new playlistOperationUnsupported error. The error occurs when a request attempts to perform an operation that is not allowed for a particular playlist. For example, a user cannot delete a video from their uploaded videos playlist or delete the playlist itself.
In all cases, this error returns a 400 HTTP response code (Bad Request).
The playlistItems.list method's watchHistoryNotAccessible and watchLaterNotAccessible errors have been removed from the documentation. While users' watch history and watch later lists are, indeed, not accessible via the API, these particular errors are not returned by the API.

15 اکتبر 2020

Two new sections have been added to the Developer Policies :

The new Section III.E.4.i provides additional information about the data collected and sent via the YouTube embedded player. You are responsible for any user data you send to us via any YouTube embedded player before the user has interacted with the player to indicate playback intent. You can limit the data shared with YouTube before a user interacts with the player by setting Autoplay to false.
The new Section III.E.4.j relates to checking the Made for Kids (MFK) status of content before embedding it on your sites and apps. You are responsible for knowing when videos that you embed on your API Client are made for kids and treating data collected from the embedded player accordingly. As such, you must check the status of content using YouTube Data API Service before embedding it on your API Client via any YouTube embedded players.

The new Finding the MadeForKids status of a video guide explains how to look up the MFK status of a video using the YouTube Data API Service .

In conjunction with these changes, a reminder has been added to the Embedded Player Parameter documentation to explain that if you enable Autoplay, playback will occur without any user interaction with the player; playback data collection and sharing will therefore occur upon page load.

8 اکتبر 2020

This update covers three small changes related to the channel resource:

The snippet.thumbnails object, which identifies a channel's thumbnail images, might be empty for newly created channels and might take up to one day to populate.
The statistics.videoCount property reflects the count of the channel's public videos only, even to owners. This behavior is consistent with counts shown on the YouTube website.
Channel keywords, which are identified in the brandingSettings.channel.keywords property, might be truncated if they exceed the maximum allowed length of 500 characters or if they contained unescaped quotation marks ( " ). Note that the 500 character limit is not a per-keyword limit but rather a limit on the total length of all keywords. This behavior is consistent with that on the YouTube website.

9 سپتامبر 2020

Note: This is a deprecation announcement.

This update covers the following API changes. All changes will go into effect on or after 9 September 2020, the date of this announcement. With that in mind, developers should no longer rely on any of the API features listed below.

The following API resources, methods, parameters, and resource properties are deprecated immediately and will stop working on or after the date of this announcement:
- The following channel resource properties:
  - The statistics.commentCount property
  - The brandingSettings.image object and all of its child properties
  - The brandingSettings.hints list and all of its child properties
- The channels.list method's categoryId filter parameter
- The guideCategories resource and the guideCategories.list method
API responses for the channels.list method no longer contain the prevPageToken property if the API request sets the managedByMe parameter to true . This change does not affect the prevPageToken property for other channels.list requests, and it does not affect the nextPageToken property for any requests.
The channel resource's contentDetails.relatedPlaylists.watchLater and contentDetails.relatedPlaylists.watchHistory properties were both announced as deprecated on 11 August 2016 . The playlistItems.insert method's and playlistItems.delete method's support for these playlists are also now fully deprecated, and the two properties have been removed from the documentation.
The channels.list method's mySubscribers parameter, which was announced as deprecated on 30 July 2013 , has been removed from the documentation. Use the subscriptions.list method and its mySubscribers parameter to retrieve a list of subscribers to the authenticated user's channel.
The channel resource's invideoPromotion object and all of its child properties, which were announced as deprecated on 27 November 2017 , have been removed from the documentation.

29 جولای 2020

We have simplified our process for charging quota for API requests by removing the additional cost associated with the part parameter. Effective immediately, we will only charge the base cost for the method that is called. You can find more information about the simplified quota here .

The effect of this change is that most API calls will have a marginally lower quota cost, while some API calls will still have the same cost. This change does not increase the cost of any API calls. Overall, the likely impact is that your allocated quota, which can be seen in the Google Cloud Console , will go a little further.

We strongly recommend that all developers complete a compliance audit for their projects to ensure continued access to the YouTube API Services.

This revision history entry was originally published on July 20, 2020.

28 جولای 2020

All videos uploaded via the videos.insert endpoint from unverified API projects created after 28 July 2020 will be restricted to private viewing mode. To lift this restriction, each project must undergo an audit to verify compliance with the Terms of Service .

Creators who use an unverified API client to upload video will receive an email explaining that their video is locked as private, and that they can avoid the restriction by using an official or audited client.

API projects created prior to 28 July 2020 are not currently affected by this change. However, we strongly recommend that all developers complete a compliance audit for their projects to ensure continued access to the YouTube API Services.

21 جولای 2020

[Updated July 28, 2020.] The documentation update referenced in this revision history entry was republished on July 28, 2020.

Yesterday, we published a documentation update related to our process for charging quota. However, due to unforeseen circumstances, the quota change is not yet in effect. As a result, the documentation has been reverted in the interest of accuracy. To avoid confusion, the revision history entry explaining the change has been removed and will be republished in the near future.

7 جولای 2020

Note: This is a deprecation announcement.

The videos.insert method's autoLevels and stabilize parameters are now deprecated, and both parameters have been removed from the documentation. Their values are ignored and do not affect the way newly uploaded videos are processed.

15 ژوئن 2020

The new Complying with the YouTube Developer Policies guide provides guidance and examples to help you ensure that your API clients adhere to specific portions of the YouTube API Services Terms and Policies (API TOS).

This guidance offers insight into how YouTube enforces certain aspects of the API TOS but does not replace any existing documents. The guide addresses some of the most common questions that developers ask during API compliance audits. We hope that it simplifies your feature development process by helping you understand how we interpret and enforce our policies.

4 ژوئن 2020

Note: This is an update to a prior deprecation announcement.

The channel bulletin feature has now been fully deprecated. This change was initially announced on 17 April 2020 and has now taken effect. As a result, the activities.insert method is no longer supported, and the activities.list method no longer returns channel bulletins. For more details, please see the YouTube Help Center .

17 آوریل 2020

Note: This is a deprecation announcement.

YouTube is deprecating the channel bulletin feature. As a result, the activities.insert method will be deprecated, and the activities.list method will stop returning channel bulletins. These changes will be effective in the API on or after May 18, 2020. For more details, please see the YouTube Help Center .

31 مارس 2020

This update contains the following changes:

New resources and methods
- The new member resource represents a channel member for a YouTube channel. A member provides recurring monetary support to a creator and receives special benefits. For example, members are able to chat when the creator turns on members-only mode for a chat.
  This resource replaces the sponsor resource, which is documented as part of the YouTube Live Streaming API. The sponsor resource is now deprecated and API clients should update calls to the sponsors.list method to use the members.list method instead.
- The new membershipsLevel resource identifies a pricing level managed by the creator that authorized the API request. The membershipsLevels.list method retrieves a list of all of the creator's membership levels.

10 ژانویه 2020

The API now supports the ability to identify child-directed content, which YouTube calls "made for kids." Learn more about "made for kids" content in the YouTube Help Center.

The channel and video resources support two new properties to enable content creators and viewers to identify content that is made for kids:

The selfDeclaredMadeForKids property enables content creators to specify whether a channel or video is made for kids.

For channels, this property can be set when calling the channels.update method. For videos, this property can be set when calling either the videos.insert or videos.update methods.

Note that this property is only included in API responses that contain channel or video resources if the channel owner authorized the API request.
The madeForKids property enables any user to retrieve the "made for kids" status of a channel or video . For example, the status might be determined based on the value of the selfDeclaredMadeForKids property. See the YouTube Help Center for more information about setting the audience for your channel, videos, or broadcasts.

We have also updated the YouTube API Services Terms of Service and Developer Policies. Please see the YouTube API Services Terms of Service - Revision History for more information. The changes to the YouTube API Services Terms of Service and Developer Policies will take effect on January 10, 2020 Pacific Time.

10 سپتامبر 2019

The API reference documentation has been updated to reflect a change to the way that subscriber counts are reported on YouTube and, consequently, in API responses. As a result of the change, subscriber counts returned by the YouTube Data API Service are rounded down to three significant figures for subscriber counts greater than 1000 subscribers. This change affects the channel resource's statistics.subscriberCount property.

Note: This change affects this property value even in cases where a user sends an authorized request for data about their own channel. Channel owners can still see exact subscriber counts in YouTube Studio.

For example, if a channel has 123,456 subscribers, the statistics.subscriberCount property will contain the value 123000 . The table below shows examples of how subscriber counts are rounded in API responses and abbreviated in other publicly visible YouTube user interfaces:

Example subscriber count	YouTube Data API	Publicly visible YouTube UIs
1,234	1230	1.23 هزار
12,345	12300	12.3 هزار
123,456	123000	123 هزار
1,234,567	1230000	1.23 میلیون
12,345,678	12300000	12.3 میلیون
123,456,789	123000000	123M

April 4, 2019

This update contains the following changes:

The API reference documentation has been updated to better explain common use cases for each method and to provide dynamic, high-quality code samples through the APIs Explorer widget. See the channels.list method's documentation for an example. There are now two new elements on pages that describe API methods:
- The APIs Explorer widget lets you select authorization scopes, enter sample parameter and property values, and then send actual API requests and see actual API responses. The widget also offers a fullscreen view that shows complete code samples, which dynamically update to use the scopes and values that you have entered.
- The Common use cases section describes one or more common use cases for the method explained on the page. For example, you could call the channels.list method to retrieve data about a specific channel or to retrieve data about the current user's channel.
  You can use links in that section to populate the APIs Explorer with sample values for your use case or to open the fullscreen APIs Explorer with those values already populated. These changes aim to make it easier for you to see code samples that are directly applicable to the use case that you're trying to implement in your own application.
Code samples are currently supported for Java, JavaScript, PHP, Python, and curl.
The code samples tool has also been updated with a new UI that offers all of the same features described above. Using that tool, you can explore use cases for different methods, load values into the APIs Explorer, and open the fullscreen APIs Explorer to get code samples in Java, JavaScript, PHP, and Python.
In conjunction with this change, the pages that previously listed available code samples for Java, JavaScript, PHP, and Python have been removed.
The quickstart guides for Java , JavaScript , PHP , and Python have been updated. The revised guides explain how to run one sample with an API key and another sample with an OAuth 2.0 client ID using code samples from the APIs Explorer.

Note that the changes described above replace an interactive tool that had been added to the API documentation in 2017.

9 جولای 2018

This update contains the following changes:

The definition of the channel resource's snippet.thumbnails property has been updated to note that when displaying thumbnails in your application, your code should use the image URLs exactly as they are returned in API responses. For example, your application should not use the http domain instead of the https domain in a URL returned in an API response.
Beginning in July 2018, channel thumbnail URLs will only be available in the https domain, which is how the URLs appear in API responses. After that time, you might see broken images in your application if it tries to load YouTube images from the http domain.
Note: This is a deprecation announcement.
The video resource's recordingDetails.location.altitude property has been deprecated. There is no guarantee that videos will return values for this property. Similarly, even if API requests attempt to set a value for that property, it is possible that the incoming data will not be stored.

22 ژوئن 2018

The Implementation guide , formerly known as the Implementation and Migration guide, has been updated to remove instructions for migrating from the v2 API to the v3 API. In addition, instructions have also been removed for features that have since been deprecated in the v3 API, such as favorite videos.

27 نوامبر 2017

This update contains the following changes:

Note: This is a deprecation announcement.
YouTube is removing support for the Featured Video and Featured Website features, which are supported in the API via the channel resource's invideoPromotion object. As a result, that object, including all of its child properties are being deprecated.
You can still retrieve and set invideoPromotion data until December 14, 2017. After that date:
- Attempts to retrieve the invideoPromotion part when calling channels.list will return an empty invideoPromotion or will not return any invideoPromotion data at all.
- Attempts to update invideoPromotion data when calling channels.update will return a successful response until at least May 27, 2018, but they will be treated as no-ops, meaning that they will not actually perform an update.
After May 27, 2018, it is possible that these requests could return error messages to indicate, for example, that invalidPromotion is an invalid part.

16 نوامبر 2017

This update contains the following changes:

The interactive code snippet tool now supports Node.js code samples. The samples are also visible in the documentation for almost all API methods, such as the channels.list method.
The customizable samples are designed to give you a use-case-specific starting point for a Node.js application. The functionality is similar to the code in the Node.js quickstart guide . However, the samples do contain some utility functions that don't appear in the quickstart:
- The removeEmptyParameters function takes a list of key-value pairs corresponding to API request parameters and removes the parameters that don't have values.
- The createResource function takes a list of key-value pairs corresponding to properties in an API resource. It then converts the properties into a JSON object that can be used in insert and update operations. The example below shows a set of property names and values and the JSON object that the code would create for them:
```
# Key-value pairs:
{'id': 'ABC123',
 'snippet.title': 'Resource title',
 'snippet.description': 'Resource description',
 'status.privacyStatus': 'private'}

# JSON object:
{
 'id': 'ABC123',
 'snippet': {
   'title': 'Resource title',
   'description': 'Resource description',
 },
 'status': {
   'privacyStatus': 'private'
 }
}
```
All of these samples are designed to be downloaded and run locally. For more information, see the prerequisites for running full code samples locally in the code snippet tool instructions.

25 اکتبر 2017

This update contains the following changes:

The Python code samples in the interactive code snippet tool have been updated to use the google-auth and google-auth-oauthlib libraries instead of the oauth2client library, which is now deprecated.
In addition to that change, the tool now provides full code samples for installed Python applications and Python web server applications, which use slightly different authorization flows. To see the full samples (and this change):
1. Go to the interactive code snippet tool or to the documentation for any API method, such as the channels.list method.
2. Click the Python tab above the code samples.
3. Click the toggle above the tabs to switch from seeing a snippet to a full sample.
4. The tab should now show a complete code sample that uses the InstalledAppFlow authorization flow. The description above the sample explains this and also links to a sample for a web server application.
5. Click the link to switch to the web server example. That sample uses the Flask web application framework and a different authorization flow.
All of these samples are designed to be downloaded and run locally. If you'd like to run the samples, see the instructions for running full code samples locally in the code snippet tool instructions.

29 آگوست 2017

This update contains the following changes:

The definition of the search.list method's forContentOwner parameter has been updated to note that if that parameter is set to true , the type parameter must be set to video .
The definition of the search.list method's regionCode parameter has been updated to clarify that the parameter restricts search results to videos that can be viewed in the specified region.
YouTube has updated its branding logos and icons. New "developed with YouTube" logos can be downloaded from the branding guidelines page. Other new YouTube logos and icons are also shown on that page and can be downloaded from the YouTube brand site .

24 جولای 2017

This update contains the following changes:

A new YouTube Data API quickstart guide is available for iOS . The guide explains how to use the YouTube Data API in a simple iOS application written in either Objective-C or Swift.
The interactive code snippet tool for the YouTube Data API now includes documentation explaining some of the tool's features:
- Executing API requests
- Toggling between code snippets and full code samples
- Using boilerplate functions
- Loading existing resources (for update methods)
Note: The tool is also embedded in API reference documentation for API methods ( example ).

1 ژوئن 2017

This update contains the following changes:

Note: This is a deprecation announcement.
The following video resource properties are being deprecated. While the properties will be supported until December 1, 2017, there is no guarantee that videos will continue to return values for those properties until that time. Similarly, videos.insert and videos.update requests that set those property values will not generate errors before that date, but it is possible that the incoming data will not be stored.

17 مه 2017

This update contains the following changes:

The API reference documentation has been updated to make code snippets more ubiquitous and interactive. Pages that explain API methods, like channels.list or videos.rate , now feature an interactive tool that lets you view and customize code snippets in Java, JavaScript, PHP, Python, Ruby, Apps Script, and Go.
For any given method, the tool shows code snippets for one or more use cases, and each use case describes a common way of calling that method. For example, you can call the channels.list method to retrieve data about a specific channel or about the current user's channel.
You can also interact with code samples:
- Modify parameter and property values, and the code snippets dynamically update to reflect the values you provide.
- Toggle between code snippets and full samples. A code snippet shows the portion of the code that calls the API method. A full sample contains that snippet as well as boilerplate code for authorizing and sending requests. Full samples can be copied and run from the command line or a local web server.
- Execute requests by clicking a button. (To execute requests, you need to authorize the tool to call the API on your behalf.)
Note that this tool has replaced the APIs Explorer on the pages where it is available. (Each page displays a link so that you also have the option of loading the request you are working on in the APIs Explorer.)
The Data API Code Snippets tool has also been updated with a new UI that offers all of the same features described above. The major new features available on this page are:
- Support for API requests that write data.
- Support for Java samples.
- More flexible and comprehensive boilerplate code for authorizing users and building API requests.

27 آوریل 2017

This update contains the following changes:

New quickstart guides explain how to set up a simple application that makes YouTube Data API requests. Guides are currently available for Android , Apps Script , Go , Java , JavaScript , Node.js , PHP , Python , and Ruby .

30 مارس 2017

This update contains the following changes:

The channel resource's new topicDetails.topicCategories[] property contains a list of Wikipedia URLs that describe the channel's content. The URLs correspond to the topic IDs returned in the resource's topicDetails.topicIds[] property.
The playlistItem resource's new contentDetails.videoPublishedAt property identifies the time that the video was published to YouTube. The resource already contains the snippet.publishedAt property, which identifies the time that the item was added to the playlist.
Like the channel resource, the video resource now returns the topicDetails.topicCategories[] property, which contains a list of Wikipedia URLs that describe the video's content. For video resources, the URLs correspond to the topic IDs returned in the resource's topicDetails.relevantTopicIds[] property.
The video resource's new contentDetails.contentRating.mpaatRating property identifies the rating that the Motion Picture Association of America gave to a movie trailer or preview.

27 فوریه 2017

As originally announced on August 11, 2016 , YouTube has switched the supported list of topic IDs to a curated list. The complete list of supported topic IDs is included in the topicDetails properties for channel and video resources as well as in the search.list method's topicId parameter.

Note that there are several changes to the curated list:

The following topics have been added as subtopics of Society :
نام topic ID
کسب و کار /m/09s1f
سلامتی /m/0kt51
نظامی /m/01h6rj
سیاست /m/05qt0
دین /m/06bvp
The Animated cartoon topic, previously a child of Entertainment , has been removed.
The Children's music topic, previously a child of Music , has been removed.

نام	topic ID
کسب و کار	`/m/09s1f`
سلامتی	`/m/0kt51`
نظامی	`/m/01h6rj`
سیاست	`/m/05qt0`
دین	`/m/06bvp`

As a result of this change, topics related to a video are now always returned in the video resource's topicDetails.relevantTopicIds[] property value.

29 نوامبر 2016

This update contains the following changes:

There are three small changes to the list of topic IDs that will be supported as of February 10, 2017:
- The Professional wrestling category, which was previously a child of the Sports category, is now a child of Entertainment .
- The TV shows category, which is a child of Entertainment , is new.
- The Health category, previously a child of Lifestyle , has been removed.
Also note that there are a few parent categories ( Entertainment , Gaming , Lifestyle , Music , and Sports ). Any video that is associated with a child category, like Tennis , will also be associated with the parent category ( Sports ).

10 نوامبر 2016

This update contains the following changes:

As first announced on August 11, 2016 , the deprecation of Freebase and the Freebase API requires several changes related to topic IDs. Topic IDs identify topics associated with channel and video resources, and you can also use the topicId search parameter to find channels or videos related to a particular topic.
On February 10, 2017, YouTube will start returning a small set of topic IDs instead of the much more granular set of IDs returned thus far. In addition, note that channels and videos are not guaranteed to be associated with any topics, which is consistent with current API behavior.
So that you can prepare your API Clients for those changes, the definitions of the following API parameters and properties have been updated to list the topic IDs that will be supported after that time. Note that the list of categories is the same for all of the properties.
- The channel resource's topicDetails.topicIds[] property.
- The video resource's topicDetails.relevantTopicIds[] property.
- The search.list method's topicId parameter.
Note: This is a deprecation announcement.
The following properties are being deprecated:
- The channel resource's topicDetails.topicIds[] property. This property will be supported until November 10, 2017.
- The video resource's topicDetails.relevantTopicIds[] property. This property will be supported until November 10, 2017.
- The video resource's topicDetails.topicIds[] property. This property will not contain values after February 10, 2017. (After that date, the topicDetails.relevantTopicIds[] property value will identify all of the topics associated with a video.)
Since Freebase has already been deprecated, the Searching with Freebase Topics guide has been removed from the documentation. That guide provided code samples to show how an application would work with the Freebase API.
In addition, several code samples related to topic IDs have been removed from the search.list method's documentation.

2 نوامبر 2016

This update contains the following changes:

New properties and parameters
- The video resource contains several new properties:
  - The player.embedHtml property contains an <iframe> tag that you can use to embed a player that plays the video. The new player.embedHeight and player.embedWidth properties identify the dimensions of the embedded player. These properties are only returned if the API request specifies a value for at least one of the maxHeight or maxWidth parameters. Those two new parameters are explained later in this revision history entry.
  - The new hasCustomThumbnail property indicates whether the video uploader has provided a custom thumbnail image for the video. Note that this property is only visible to the video uploader.
  - The new fpbRatingReasons[] identifies reasons that the video received its FPB (South Africa) rating.
  - The new mcstRating identifies the rating that the video received in Vietnam.
- The videos.list method supports two new parameters, maxHeight and maxWidth . You can use either parameter or both parameters when retrieving the player part in video resources.
  By default, the height of the <iframe> returned in the player.embedHtml property is 360px. The width adjusts to match the video's aspect ratio, thereby ensuring that the embedded player does not have black bars framing the video. So, for example, if a video's aspect ratio is 16:9, the player's width would be 640px.
  With the new parameters, you can specify that instead of the default dimensions, the embed code should use a height and/or width appropriate for your application layout. The API server scales the player dimensions as appropriate to ensure that the embedded player does not have black bars framing the video. Note that both parameters specify the maximum dimensions of the embedded player. Thus, if both parameters are specified, one dimension might still be smaller than the maximum amount allowed for that dimension.
  For example, suppose a video has a 16:9 aspect ratio. Thus, the player.embedHtml tag would contain a 640x360 player if the maxHeight or maxWidth parameter is not set.
  - If the maxHeight parameter is set to 720 , and the maxWidth parameter is not set, the API would return a 1280x720 player.
  - If the maxWidth parameter is set to 960 , and the maxHeight parameter is not set, the API would return a 960x540 player.
  - If the maxWidth parameter is set to 960 , and the maxHeight parameter is set to 450 , the API would return an 800x450 player.
  The new player.embedHeight and player.embedWidth properties, which are described above, identify the player's dimensions.
Updates to existing methods, properties and parameters
- The channelSection resource description has been updated to note that a channel can create a maximum of 10 shelves without setting targeting data and can create a maximum of 100 shelves with targeting data.
  In addition, the channelSection resource's targeting property has been updated to reflect the fact that targeting options can only be set using the API. Targeting options are deleted if the channel section is modified using the user interface on the YouTube website.
- The definition of the i18nLanguage resource's snippet.name property has been corrected to reflect that the value represents a language's name as it is written in the language specified by the i18nLanguage.list method's hl parameter.
- The playlistItem resource's contentDetails.note property has been updated to note that the property value's maximum length is 280 characters.
- The playlistItem resource's contentDetails.startAt and contentDetails.endAt properties have been deprecated. These fields are ignored if they are set in playlistItems.insert or playlistItems.update requests.
- The playlistItems.delete and playlistItems.update methods now support the onBehalfOfContentOwner parameter, which is already supported for several other methods. Requests that use that method also need to be authorized with a token that provides access to the https://www.googleapis.com/auth/youtubepartner scope.
- The search.list method's publishedBefore and publishedAfter parameters have both been updated to indicate that the parameter values are inclusive. So, for example, if the publishedBefore parameter is set, the API returns resources created before or at the specified time.
- The video resource's contentDetails.contentRating.grfilmRating property supports three additional values: grfilmK12 , grfilmK15 , and grfilmK18 .
- The videos.insert method description has been updated to note that the maximum file size for uploaded videos has increased from 64GB to 128GB.

New and updated errors

The API supports the following new errors:

نوع خطا	جزئیات خطا	شرح
`forbidden (403)`	`homeParameterDeprecated`	The `activities.list` method returns this error to indicate that the user's home page activity data is not available through this API. This error might occur if you set the `home` parameter to `true` in an unauthorized request.
`invalidValue (400)`	`invalidContentDetails`	The `playlistItems.insert` method returns this error to indicate that the `contentDetails` object in the request is invalid. One reason that this error occurs is that the `contentDetails.note` field is longer than 280 characters.
`forbidden (403)`	`watchHistoryNotAccessible`	The `playlistItems.list` method returns this error to indicate that the request tried to retrieve "watch history" playlist items, but those cannot be retrieved using the API.
`forbidden (403)`	`watchLaterNotAccessible`	The `playlistItems.list` method returns this error to indicate that the request tried to retrieve "watch later" playlist items, but those cannot be retrieved using the API.
`badRequest (400)`	`uploadLimitExceeded`	The `videos.insert` method returns this error to indicate that the channel has exceeded the number of videos that it may upload.
`forbidden (403)`	`forbiddenEmbedSetting`	The `videos.update` method returns this error to indicate that the API request attempts to set an invalid embed setting for the video. Note that some channels may not have permission to offer embedded players for live streams. See the YouTube Help Center for more information.

The playlistItems.insert method no longer returns an error if you insert a duplicate video into a playlist. That error previously occurred for some playlists, like favorite videos, that did not allow duplicates but are no longer supported. In general, playlists do allow duplicate videos.

Other updates
- The revision history entry for September 15, 2016, has been updated to clarify that, whenever the channel resource's contentDetails.relatedPlaylists.watchHistory and contentDetails.relatedPlaylists.watchLater properties are included in a response, they always contain the values HL and WL , respectively. Moreover, those properties are only included if an authorized user is retrieving data about the user's own channel.

15 سپتامبر 2016

This update contains the following changes:

The August 11, 2016, revision history update discussed several changes related to topic IDs, including the fact that the set of supported topic IDs will change as of February 10, 2017. The list of topics that will be supported will be published by November 10 ، 2016.
The following changes are now in effect. Notice of these changes was given in the revision history update on August 11, 2016:
- If the activities.list method is called with the home parameter set to true , the API response now contains items similar to what a logged-out YouTube user would see on the home page.
  This is a slight change that is intended to provide a better user experience than the behavior described in the revision history update on August 11, 2016. That update had stated that requests using the home parameter would return an empty list.
- The channel resource's contentDetails.relatedPlaylists.watchHistory and contentDetails.relatedPlaylists.watchLater properties now contain values of HL and WL , respectively, for all channels.
  To be clear, these properties are only visible to an authorized user retrieving data about the user's own channel. The properties always contain the values HL and WL , even for an authorized user retrieving data about the user's own channel. Thus, the watch history and watch later playlist IDs cannot be retrieved via the API.
  In addition, requests to retrieve playlist details ( playlists.list ) or playlist items ( playlistItems.list ) for a channel's watch history or watch later playlist now return empty lists. This behavior is true for the new values, HL and WL , as well as for any watch history or watch later playlist IDs that your API Client may have already stored.
The video resource's fileDetails.recordingLocation object and its child properties are no longer returned. Previously, this data (like the parent fileDetails object) could only be retrieved by a video's owner.

11 آگوست 2016

This update contains the following changes:

The newly published YouTube API Services Terms of Service ("the Updated Terms"), discussed in detail on the YouTube Engineering and Developers Blog , provides a rich set of updates to the current Terms of Service. In addition to the Updated Terms , which will go into effect as of February 10, 2017, this update includes several supporting documents to help explain the policies that developers must follow.
The full set of new documents is described in the revision history for the Updated Terms . In addition, future changes to the Updated Terms or to those supporting documents will also be explained in that revision history. You can subscribe to an RSS feed listing changes in that revision history from a link in that document.
The deprecation of Freebase and the Freebase API is causing several changes related to topic IDs. Topic IDs are used in the following API resources and methods:
- The channel resource's topicDetails part identifies topics associated with the channel.
- The video resource's topicDetails part identifies topics associated with the video.
- The search.list method's topicId parameter lets you search for videos or channels related to a particular topic.
The changes to these features are:
- As of February 10, 2017, YouTube will start returning a small set of topic IDs instead of the much more granular set of IDs returned thus far. That set of supported topics will identify high-level categorizations like Sports or Basketball , but, for example, they will not identify specific teams or players. We will be announcing the set of supported topics so that you have time to prepare your application for this change.
- Any Freebase topic IDs that you have already retrieved can be used to search for content until February 10, 2017. However, after that time, you will be able to use only the smaller set of topics identified in the previous item to retrieve search results by موضوع.
- After February 10, 2017, if you try to search for results using a topic ID that is not in the smaller set of supported topic IDs, the API will return an empty result set.
Several API fields and parameters are being deprecated effective September 12, 2016:
- The activities.list method's home parameter enabled an authorized user to retrieve the activity feed that would display on the YouTube home page for that user. Requests that use this parameter after September 12, 2016, will return an empty list.
- The channel resource's contentDetails.relatedPlaylists.watchHistory and contentDetails.relatedPlaylists.watchLater properties are only visible to an authorized user retrieving data about the user's own channel. After September 12, 2016, the contentDetails.relatedPlaylists.watchHistory will return a value of HL and the contentDetails.relatedPlaylists.watchLater property will return a value of WL for all channels.
  Requests to retrieve playlist details ( playlists.list ) for a channel's watch history or watch later playlist will return an empty list after September 12, 2016. Requests to retrieve playlist items ( playlistItems.list ) in either of those playlists will also return an empty list after that time. This is true for the new values, HL and WL , as well as for any watch history or watch later playlist IDs that your API Client may have already stored.
- The video resource's fileDetails.recordingLocation object or any of its child properties will no longer be returned after September 12, 2016. This data can only be retrieved by a video's owner since the parent fileDetails object can only be retrieved by a video owner.

13 ژوئن 2016

This update contains the following changes:

The channel resource's contentDetails.googlePlusUserId property has been deprecated. Previously, the property was only present if the channel was associated with a Google+ profile. Following the deprecation, the property will no longer be included in any channel resources.
The comment resource's snippet.authorGoogleplusProfileUrl property has been deprecated. Previously, the property was only present if the channel was associated with a Google+ profile. Following the deprecation, the property will no longer be included in any comment resources.

Since neither of these properties will be returned following the deprecation, both properties have been removed from the corresponding resource documentation.

31 مه 2016

This update contains the following changes:

The subscriptions.list method's new myRecentSubscribers parameter retrieves a list of the subscribers of the authenticated user's channel in reverse chronological order of the time that they subscribed to the channel.
Note that the new parameter only supports retrieval of the most recent 1000 subscribers to the authenticated user's channel. To retrieve a complete list of subscribers, use the mySubscribers parameter. That parameter, which does not return subscribers in a particular order, does not limit the number of subscribers that can be retrieved.
The definition of the snippet.thumbnails.(key) property has been updated for the activity , playlistItem , playlist , search result , thumbnail , and video resources to note that additional thumbnail image sizes are available for some videos.
- The standard image is 640px wide and 480px tall.
- The maxres image is 1280px wide and 720px tall.
The definition of the channelSection.list method's part parameter has been updated to note that the targeting part can be retrieved at a cost of 2 quota units.
The videos.list method now returns a forbidden ( 403 ) error when an improperly authorized request tries to retrieve the fileDetails , processingDetails , or suggestions parts of a video resource. Those parts are only available to the video's owner.

17 مه 2016

The new Data API Code Snippets tool provides short code snippets for common YouTube Data API use cases. Code snippets are currently available for all read-only API methods in Apps Script, Go, JavaScript, PHP, Python, and Ruby.

For each method, the tool shows code samples for one or more use cases. For example, it provides five code snippets for the search.list method:

List videos by keyword
List videos by location
List live events
Search for the authenticated user's videos
List related videos

For each use case, the tool displays the parameters used in the API request. You can modify the parameter values, in which case the tool updates the code snippets to reflect the parameter values that you provided.

Finally, the tool displays the API response to each request. If you have modified the request parameters, the API response is based on your provided parameter values. Note that you need to authorize the tool to submit requests on your behalf for API responses to display.

28 آوریل 2016

This update contains the following changes:

The video resource's new contentDetails.projection property specifies the video's projection format. Valid property values are 360 and rectangular .
The video resource's recordingDetails.location and fileDetails.recordingLocation properties have both been updated to explain the difference between the two properties:
- The recordingDetails.location property identifies the location that the video owner wants to associate with the video. This location is editable, searchable on public videos, and might be displayed to users for public videos.
- The fileDetails.recordingLocation property value is immutable and represents the location associated with the original, uploaded video file. The value is only visible to the video owner.
The definition of the channel resource's contentDetails.relatedPlaylists.favorites property has been updated to note that the property value might contain a playlist ID that refers to an empty playlist and that cannot be fetched. This is due to the fact that favorite videos functionality has already been deprecated. Note that this property is not subject to the API deprecation policy .
The definition of the ineligibleAccount error, which can be returned by the comments.insert , comments.update , commentThreads.insert , or commentThreads.update method, has been updated to reflect that the error occurs when the YouTube account used to authorize the API request has not been merged with the user's Google account.

20 آوریل 2016

This update contains the following changes:

The definition of the channels.update method's part parameter has been updated to note that localizations is also a valid value for that parameter.
The Quota Usage section of the Getting Started guide has been updated to link to the Google Developer's Console, where you can see your actual quota and quota usage.

16 مارس 2016

This update contains the following changes:

Updates to existing resources and methods
- The channelBanner resource documentation has been updated to note that the recommended size for the uploaded channel banner image is 2560px by 1440px. The minimum size (2048px by 1152px) has not changed.
- The channel resource's new snippet.customUrl property identifies the custom URL associated with the channel. (Not all channels have custom URLs.) The YouTube Help Center explains eligibility requirements for getting a custom URL as well as how to set up the URL.
- The channel resource's brandingSettings.watch object and all of its child properties have been deprecated.
- The API response to a search.list request now contains a regionCode property. The property identifies the region code that was used for the search query. The region code instructs the API to return search results for the specified country.
  The property value is a two-letter ISO country code that identifies the region. The i18nRegions.list method returns a list of supported regions. The default value is US . If a non-supported region is specified, YouTube might still select another region, rather than the default value, to handle the query.
- The definitions of the videoAbuseReportReason resource's snippet.label and snippet.secondaryReasons[].label properties have been updated to note that the properties contain localized label text for the abuse report reasons.
  In addition, the videoAbuseReportReasons.list method now supports the hl parameter, which specifies the language that should be used for label text in the API response. The default parameter value is en_US .
- The video resource's new contentDetails.contentRating.ecbmctRating property identifies a video's rating from Turkey's Evaluation and Classification Board of the Ministry of Culture and Tourism.
  In addition, API properties for other rating systems support the following new property values:
  - contentDetails.contentRating.fpbRating (South Africa)
    Rating: 10; property value: fpb10
  - contentDetails.contentRating.moctwRating (Taiwan)
    Rating: R-12; property value: moctwR12
  - contentDetails.contentRating.moctwRating (Taiwan)
    Rating: R-15; property value: moctwR15
- The video resource's liveStreamingDetails.activeLiveChatId property contains the ID of the active live chat associated with the video. The property value is only present if the video is a current live broadcast that has live chat enabled. After the broadcast ends and the live chat concludes, the property is no longer returned for the video.
- The video resource's status.rejectionReason property supports the new property value legal .

The API supports the following new errors:

نوع خطا	جزئیات خطا	شرح

European Union (EU) laws require that certain disclosures must be given to and consents obtained from end users in the EU. Therefore, for end users in the European Union, you must comply with the EU User Consent Policy . We have added a notice of this requirement in our YouTube API Terms of Service .

19 نوامبر 2015

The API now supports the ability to set and retrieve localized text for the snippet.title and snippet.description properties of the playlist and video resources, the snippet.title property of the channelSection resource, and the snippet.description property of the channel resource.

Setting localized titles and descriptions
You can set localized values for a resource when calling the insert or update method for that resource. To set localized values for a resource, do both of the following:
- Ensure that a value is set for the resource's snippet.defaultLanguage property. That property identifies the language of the resource's snippet.title and snippet.description properties. Its value can be any supported application language or most other ISO 639-1:2002 language codes. For example, if you upload a video that has an English title and description, you would set the snippet.defaultLanguage property to en .
  Note for updating channel resources: To set the snippet.defaultLanguage property for a channel resource, you actually need to update the brandingSettings.channel.defaultLanguage property.
- Add the localizations object to the resource you are updating. Each object key is a string that identifies an application language or ISO 639-1:2002 language code, and each key maps to an object that contains the localized title (and description) for the resource.
  The sample snippet below sets the resource's default language to English. It also adds localized German and Spanish titles and descriptions to a video:
```
{
  "kind": "youtube#video",
  ...
  "snippet": {
    "title": "Playing soccer",
    "description": "We play soccer in the park on Sundays.",
    "defaultLanguage": "en",
    ...
  },
  "localizations":
    "de": {
      "title": "Fußball spielen",
      "description": "Wir spielen Fußball im Park am Sonntag"
    },
    "es": {
      "title": "Jugar al fútbol",
      "description": "Nosotros jugamos fútbol en el parque los domingos",
    }
  }
}
```
Retrieving localized values
The API supports two ways to retrieve localized values for a resource:
- Add the hl parameter to your channels.list , channelSections.list , playlists.list , or videos.list request to retrieve localized data for a specific application language that the YouTube website supports . If localized resource details are available in that language, the resource's snippet.localized object will contain the localized values. However, if localized details are not available, the snippet.localized object will contain resource details in the resource's default language .
  For example, suppose a videos.list request retrieved data for the video described above with localized German and Spanish data. If the hl parameter were set to de , the resource would contain the following data:
```
{
  "kind": "youtube#video",
  ...
  "snippet": {
    "title": "Playing soccer",
    "description": "We play soccer in the park on Sundays.",
    "defaultLanguage": "en",
    "localized": {
      "title": "Fußball spielen",
      "description": "Wir spielen Fußball im Park am Sonntag"
    }
    ...
  }
}
```
  However, if the hl parameter were set to fr , the snippet.localized object would contain the English title and description because English is the default language for the resource, and localized French details are not available.
  Important: The hl parameter only supports values that identify application languages that the YouTube website supports. To determine whether localized text is available for other languages, you need to retrieve the localizations part for the resource and filter to determine whether the localized text exists.
  
  For example, you would need to retrieve the full list of localizations to determine whether localized text is available in Appalachian English.
- When retrieving a resource, include localizations in the part parameter value to retrieve all of the localized details for that resource. If you are retrieving localized data for a language that is not a current YouTube application language , you need to use this approach to retrieve all localizations and then filter to determine whether the desired localized data exists.

Errors related to localized text values

The API also supports the following new errors for localized text values:

نوع خطا	جزئیات خطا	شرح
`badRequest (400)`	`defaultLanguageNotSetError`	This error indicates that a request that tries to insert or update the `localizations` object for a resource is failing because the `snippet.defaultLanguage` property is not set for that resource. The `channels.update` , `channelSections.insert` , `channelSections.update` , `playlists.insert` , `playlists.update` , `videos.insert` , and `videos.update` methods support this error.
`badRequest (400)`	`localizationValidationError`	This error indicates that one of the values in a resource's `localizations` object failed to validate. For example, this error might occur if the object contains an invalid language code. The `channels.update` , `channelSections.insert` , `channelSections.update` , `playlists.insert` , and `playlists.update` methods support this error.

4 نوامبر 2015

This update contains the following changes:

Updates to existing resources and methods
- The search.list method's order parameter has been updated to note that if you sort live broadcasts by viewCount , the API results are sorted by the broadcasts' number of concurrent viewers while the broadcasts are still ongoing.
- The search.list method's relatedToVideoId parameter has been updated to note that if the parameter is set, the only other supported parameters are part , maxResults , pageToken , regionCode , relevanceLanguage , safeSearch , type (which must be set to video ), and fields . This update does not reflect a change in API behavior.
- The definition of the video resource's snippet.publishedAt property has been updated to note that the property value, which specifies the date and time that the video was published, might be different than the time that the video was uploaded. For example, if a video is uploaded as a private video and then made public at a later time, the property value specifies the time that the video was made public. The updated definition also explains how the value is populated for private and unlisted videos.
  This change does not reflect a change in API behavior.
- The definition of the video resource's status.publishAt property has been updated to note:
  - If you set this property's value when calling the videos.update method, you must also set the status.privacyStatus property value to private even if the video is already private.
  - If the request schedules a video to be published at some time in the past, it is published right away. As such, the effect of setting the status.publishAt property to a past date and time is the same as of changing the video's privacyStatus from private to public .
- The video resource's contentDetails.contentRating.cncRating property specifies the video's rating from France's Commission de classification cinematographique. This property replaces the contentDetails.contentRating.fmocRating property, which is now deprecated.
- The definition of the channel resource's brandingSettings.channel.keywords has been updated to correctly reflect that the property value contains a space-separated list of strings and not a comma-separated list, as previously documented. This update does not reflect a change in API behavior.
- The documentation for the thumbnails.set method has been updated to accurately reflect that the body of the request contains the thumbnail image that you are uploading and associating with a video. The request body does not contain a thumbnail resource. Previously, the documentation said that you should not provide a request body when calling this method. This update does not reflect a change in API behavior.
- The description of the activity resource has been updated to reflect the fact that the activities.list method does not currently include resources related to new video comments. The resource's snippet.type and contentDetails.comment have been updated as well.

New and updated errors

The API now supports the following errors:

28 آگوست 2015

This update contains the following changes:

Updates to existing resources and methods
- The video resource's statistics.favoriteCount property has been deprecated.
  In accordance with our deprecation policy, this property will continue to be included in video resources for at least one year after this announcement. However, the property value is now always set to 0 .

7 آگوست 2015

This update contains the following changes:

Updates to existing resources and methods
- The definition of the video resource's snippet.tags[] property has been updated to provide more information about how the API server calculates the length of the property's value. Note that this update does not reflect a change in the API's behavior.
  Specifically, the definition now explains that if a tag contains a space, the API server handles the tag value as though it were wrapped in quotation marks, and the quotation marks count toward the character limit. So, for the purposes of character limits, the tag Foo-Baz contains seven characters, but the tag Foo Baz contains nine characters.
- The commentThreads.insert method no longer supports the shareOnGooglePlus parameter, which previously indicated whether a comment and replies to that comment should also be posted to the author's Google+ profile. If a request submits the parameter, the API server ignores the parameter but otherwise handles the request.

18 ژوئن 2015

This update contains the following changes:

Updates to existing resources and methods
- The commentThreads.list method's new order parameter specifies the order in which the API response should list comment threads. Threads can be ordered by time or relevance. The default behavior is to order them by time.
- The video resource's new snippet.defaultAudioLanguage property specifies the language spoken in the video's default audio track.
- The definition of the video resource's contentDetails.licensedContent property has been updated to clarify that the content must have been originally uploaded to a channel linked to a YouTube content partner and then claimed by that partner. This does not represent a change in actual API behavior.
- The captions.delete , captions.download , captions.insert , captions.list , and captions.update methods now support the onBehalfOfContentOwner parameter, which is already supported for several other methods. Requests that use that method also need to be authorized with a token that provides access to the https://www.googleapis.com/auth/youtubepartner scope.

27 آوریل 2015

This update contains the following changes:

New resources and methods
- The new videoAbuseReportReason resource contains information about a reason that a video would be flagged for containing abusive content. The videoAbuseReportReasons.list method lets you retrieve a list of all of the reasons why videos might be flagged.
- The new videos.reportAbuse method provides a way to actually flag a video that contains abusive content. The body of the request contains a JSON object that specifies the video being flagged as well as the reason that the video is deemed to contain abusive content. Valid reasons can be obtained from the videoAbuseReportReason.list method described above.
  The migration guide has also been updated with an example for reporting an abusive video. With this change, the v3 API now supports all of the v2 API features that it is scheduled to support. These features are also all explained in the migration guide.
Updates to existing resources and methods
- The search.list method's new forDeveloper filter parameter restricts a search to only retrieve videos uploaded via the developer's application or website. The forDeveloper parameter can be used in conjunction with optional search parameters like the q parameter.
  For this feature, each uploaded video is automatically tagged with the project number that is associated with the developer's application in the Google Developers Console .
  When a search request subsequently sets the forDeveloper parameter to true , the API server uses the request's authorization credentials to identify the developer. Therefore, a developer can restrict results to videos uploaded through the developer's own app or website but not to videos uploaded through other apps or sites.
  The new feature offers functionality that is similar, albeit not identical, to the developer tags functionality that the v2 API supported.
- The channel resource's new snippet.country property lets channel owners associate their channels with a particular country.
  Note: To set the snippet.country property for a channel resource, you actually need to update the brandingSettings.channel.country property.
- The API now supports targeting for channelSection resources. Channel section targeting provides a way to restrict visibility of a content section to users that match particular criteria.
  The API exposes three targeting options. A user must meet all of the targeting settings for a channel section to be visible.
  - targeting.languages[] : A list of YouTube application languages . Users who have chosen one of those languages can see the corresponding channel section.
  - targeting.regions[] : A list of YouTube preferred content regions . The channel section is visible to users that have selected one of those regions as well as users for whom one of those regions is automatically selected.
  - targeting.countries[] : A list of countries where the channel section is visible. Each value in the list is an ISO 3166-1 alpha-2 country code .
- The definition of the video resource's contentDetails.duration property has been corrected to reflect that the value can reflect hours, days, and so forth.
- The documentation for the channelSections.delete , playlistItems.delete , playlists.delete , subscriptions.delete , and videos.delete method has been corrected to reflect that, when successful, those methods all return an HTTP 204 response code ( No Content ).

New and updated errors

The API now supports the following errors:

نوع خطا	جزئیات خطا	شرح
`badRequest (400)`	`targetInvalidCountry`	The `channelSections.insert` and `channelSections.update` methods return this error if the inserted `channelSection` resource contained an invalid value for the `targeting.countries[]` property.
`badRequest (400)`	`targetInvalidLanguage`	The `channelSections.insert` and `channelSections.update` methods return this error if the inserted `channelSection` resource contained an invalid value for the `targeting.languages[]` property.
`badRequest (400)`	`targetInvalidRegion`	The `channelSections.insert` and `channelSections.update` methods return this error if the inserted `channelSection` resource contained an invalid value for the `targeting.regions[]` property.
`badRequest (400)`	`operationNotSupported`	The `comments.insert` method returns this error if the API user is not able to insert a comment in reply to the top-level comment identified by the `snippet.parentId` property. In a `commentThread` resource, the `snippet.canReply` property indicates whether the current viewer can reply to the thread.
`badRequest (400)`	`invalidChannelId`	The `search.list` method returns this error if the `channelId` parameter in the request specified an invalid channel ID.
`badRequest (400)`	`subscriptionForbidden`	The `subscriptions.insert` method returns this error if the API user tries to subscribe to the user's own channel.

The captions.update method no longer supports the invalidMetadata and videoNotFound errors.

16 آوریل 2015

This update contains the following changes:

The migration guide has been updated to explain how to migrate applications still using comments functionality from the v2 API.
The guide also calls out several commenting features that the v2 API did not support but that are supported in the v3 API . این شامل:
- Retrieving comments about a channel
- Retrieving all comment threads related to a channel, which means that the API response can contain comments about the channel or any of its videos.
- Updating the text of a comment
- Marking a comment as spam
- Setting a comment's moderation status
The Subscribing to push notifications guide has been updated to reflect the fact that notifications are only pushed to the Google PubSubHubBub hub and not also to the Superfeedr hub as previously indicated.

9 آوریل 2015

This update contains the following changes:

The API's new commentThread and comment resources let you retrieve, insert, update, delete, and moderate comments.
- A commentThread resource contains information about a YouTube comment thread, which comprises a top-level comment and replies, if any exist, to that comment. A commentThread resource can represent comments about either a video or a channel.
  The top-level comment and the replies are actually comment resources that are nested inside the commentThread resource. It is important to note that the commentThread resource does not necessarily contain all replies to a comment, and you need to use the comments.list method if you want to retrieve all replies for a particular comment. In addition, some comments do not have replies.
  The API supports the following methods for commentThread resources:
  - commentThreads.list – Retrieve a list of comment threads. Use this method to retrieve comments associated with a particular video or channel.
  - commentThreads.insert – Create a new top-level comment. (Use the comments.insert method to reply to an existing comment.)
  - commentThreads.update – Modify a top-level comment.
- A comment resource contains information about a single YouTube comment. A comment resource can represent a comment about either a video or a channel. In addition, the comment could be a top-level comment or a reply to a top-level comment.
  The API supports the following methods for comment resources:
  - comments.list – Retrieve a list of comment. Use this method to retrieve all of the replies to a particular comment.
  - comments.insert – Create a reply to an existing comment.
  - comments.update – Modify a comment.
  - comments.markAsSpam – Flag one or more comments as spam.
  - comments.setModerationStatus – Set the moderation status of one or more comments. For example, clear a comment for public display or reject a comment as unfit for display. The API request must be authorized by the owner of the channel or video associated with the comments..
  - comments.delete – Delete a comment.
Note that the API's new https://www.googleapis.com/auth/youtube.force-ssl scope, described in the revision history for April 2, 2015 , is required for calls to the comments.insert , comments.update , comments.markAsSpam , comments.setModerationStatus , comments.delete , commentThreads.insert , and commentThreads.update methods.
The new Subscribing to push notifications guide explains the API's new support for push notifications via PubSubHubBub , a server-to-server publish/subscribe protocol for Web-accessible resources. Your PubSubHubBub callback server can receive Atom feed notifications when a channel does any of the following activities:
- uploads a video
- updates a video's title
- updates a video's description
The migration guide has also been updated to note the new support for push notifications. However, since the v2 API supported numerous other types of push notifications that are not supported in the v3 API, the mention of PubSubHubBub support is still listed in the Deprecated section of that guide.
The API's new https://www.googleapis.com/auth/youtube.force-ssl scope is now a valid scope for any API method that previously supported the https://www.googleapis.com/auth/youtube scope.
The API now supports the following errors:
نوع خطا جزئیات خطا شرح
badRequest (400) invalidRating The videos.rate method returns this error if the request contained an unexpected value for the rating parameter.
The subscriptions.insert method no longer supports the subscriptionLimitExceeded error, which previously indicated that the subscriber identified with the request had exceeded the subscription rate limit.

2 آوریل 2015

This update contains the following changes:

The new captions resource represents a YouTube caption track. A caption track is associated with exactly one YouTube video.
The API supports methods to list , insert , update , download , and delete caption tracks.
The migration guide has also been updated to explain how to migrate applications still using captions functionality in the v2 API.
The API's new https://www.googleapis.com/auth/youtube.force-ssl scope requires communication with the API server to happen over an SSL connection.
This new scope grants the same access as the https://www.googleapis.com/auth/youtube scope. And, in fact, those two scopes are functionally identical because the YouTube API server is only available via an HTTPS endpoint. As a result, even though the https://www.googleapis.com/auth/youtube scope does not require an SSL connection, there is actually no other way to make an API request.
The new scope is required for calls to the all of the caption resource's methods.

11 مارس 2015

This update contains the following changes:

The YouTube Data API (v3) migration guide contains a new tab, named New in the v3 API , that lists features that the v3 API does support and that the v2 API did not support. The same features were previously and are still listed in other tabs in the guide. For example, the new feature explaining how to update a channel's in-video promotional campaign data is also listed under the Channels (profiles) tab.
The YouTube Data API (v3) migration guide has been updated to note that the v3 API will support the following v2 API feature:
- Flagging a video
The YouTube Data API (v3) migration guide has been updated to note that the following v2 API features will not be supported in the v3 API:
- Retrieve video recommendations – The v3 API does not retrieve a list that only contains videos recommended for the current API user. However, you can use the v3 API to find recommended videos by calling the activities.list method and setting the home parameter value to true .
  In the API response, a resource corresponds to a recommended video if the snippet.type property's value is recommendation . In that case, the contentDetails.recommendation.reason and contentDetails.recommendation.seedResourceId properties will contain information about why the video was recommended. Note that there is no guarantee that the response will contain any particular number of recommended videos.
- Retrieve channel suggestions
- Retrieve new subscription videos – The v3 API does not retrieve a list that only contains videos that have recently been uploaded to channels that the API user subscribes to. However, you can use the v3 API to find new subscription videos by calling the activities.list method and setting the home parameter value to true .
  In the API response, a resource corresponds to a new subscription video if the snippet.type property's value is upload . Note that there is no guarantee that the response will contain any particular number of new subscription videos.
- RSS feed support
- Push notifications for feed updates – The v2 API supported push notifications, using either the Simple Update Protocol (SUP) or PubSubHubbub , to monitor user activity feeds for YouTube users. Notifications were provided for new channel subscriptions and when videos were rated, shared, marked as favorites, commented on, or uploaded.
  The v3 API will support push notifications using the PubSubHubbub protocol , but the notifications will only cover video uploads and updates to video titles or video descriptions.
- Channel location – The v2 API used the <yt:location> tag to identify the user's location as entered in the channel's YouTube public profile. While some developers used this field to associate a channel with a particular country, the field's data could not consistently be used for that purpose.
- Set or retrieve developer tags – The v2 API supported the ability to associate keywords, or developer tags, with a video at the time that the video was uploaded. Developer tags would not be displayed to YouTube users, but video owners could retrieve videos that matched a specific developer tag.
  The v3 API will provide a similar, but not identical, feature. Specifically, a developer will be able to search for videos uploaded by the developer's own application. For this feature, each uploaded video is automatically tagged with the project number that is associated with the developer's application in the Google Developers Console . The developer then uses the same project number to search for videos.
- List videos by publication date, viewcount, or rating – In the v2 API, the orderby parameter let you sort videos in a playlist by position, duration, publication date, title, and several other values. In the v3 API, playlist items are typically sorted by position in ascending order and other sorting options are not available.
  چند استثنا وجود دارد. A new upload, favorite video, liked video, or recently watched video is automatically added as the first item ( snippet.position = 0 ) for the following types of playlists. So, each of these lists is effectively sorted in order of newest to oldest item based on the times that items were added to the list.
  - user uploads
  - ویدیوهای مورد علاقه
  - liked videos
  - watch history
  Note, however, that a new item added to the "Watch later" playlist is added as the last item in that list, so that list is effectively sorted from oldest to newest item.
- Batch processing – The v3 API supports one of the batch processing use cases that the v2 API had supported. The v3 API's channels.list , channelSections.list , guideCategories.list , playlistItems.list , playlists.list , subscriptions.list , videoCategories.list , and videos.list methods all support an id parameter, which can be used to specify a comma-delimited list of IDs (video IDs, channel IDs, etc.). Using those methods, you can retrieve a list of multiple resources with a single request.
With these changes, the guide now identifies all functionality that was supported in the old (v2) API that will be deprecated in the current API version (v3).

4 مارس 2015

This update contains the following changes:

The channelSections.delete and channelSections.update methods now support the onBehalfOfContentOwner parameter, which is already supported for several other methods.
The following properties and their child properties have been deprecated:
- brandingSettings.image.backgroundImageUrl
- brandingSettings.image.largeBrandedBannerImageImapScript
- brandingSettings.image.largeBrandedBannerImageUrl
- brandingSettings.image.smallBrandedBannerImageImapScript
- brandingSettings.image.smallBrandedBannerImageUrl
Note: None of these properties had been subject to the API Deprecation Policy.
The video resource's new contentDetails.contentRating.contentDetails.contentRating.djctqRatingReasons property identifies the reasons that explain why the video received its DJCQT (Brazil) rating.

The API now supports the following errors:

نوع خطا	جزئیات خطا	شرح
`notFound (404)`	`channelNotFound`	The `channels.update` method returns this error if the request's `id` parameter specifies a channel that cannot be found.
`badRequest (400)`	`manualSortRequiredinvalidValue`	The `playlistItems.insert` and `playlistItems.update` methods return this error if the request attempts to set the playlist item's position, but the playlist does not use manual sorting. For example, playlist items might be sorted by date or popularity. You can address this error by removing the `snippet.position` element from the resource sent in the request body. If you want the playlist item to have a specific position in the list, you need to first update the playlist's ordering setting to Manual . THis setting can be adjusted in the YouTube Video Manager .
`forbidden (403)`	`channelClosed`	The `playlists.list` method returns this error if the request's `channelId` parameter specifies a channel that has been closed.
`forbidden (403)`	`channelSuspended`	The `playlists.list` method returns this error if the request's `channelId` parameter specifies a channel that has been suspended.
`forbidden (403)`	`playlistForbidden`	The `playlists.list` method returns this error if the request's `id` parameter does not support the request or the request is not properly authorized.
`notFound (404)`	`channelNotFound`	The `playlists.list` method returns this error if the request's `channelId` parameter specifies a channel that cannot be found.
`notFound (404)`	`playlistNotFound`	The `playlists.list` method returns this error if the request's `id` parameter specifies a playlist that cannot be found.
`notFound (404)`	`videoNotFound`	The `videos.list` method returns this error if the request's `id` parameter specifies a video that cannot be found.
`badRequest (400)`	`invalidRating`	The `videos.rate` method returns this error if the request contains an unexpected value for the `rating` parameter.

2 مارس 2015

This update contains the following changes:

The search.list method now supports the relevanceLanguage parameter, which lets you request results that are most relevant to a particular language.
The YouTube Data API (v3) migration guide has also been updated to explain how to use this new parameter. The parameter addresses a feature gap that previously existed between the current API version (v3) and the previous version (v2), which has already been deprecated.
The YouTube Data API (v3) migration guide has also been updated to indicate the deprecation of the special feeds and metadata fields that the v2 API provided for describing movies, trailers, television shows, television seasons, and television episodes.

14 ژانویه 2015

This update contains the following changes:

The YouTube Data API (v3) migration guide has been updated to explain how to use the v3 API to upload videos using JavaScript. (See the Upload a video section for details.) This functionality is comparable to the browser-based uploading functionality that the v2 API supports. Note that this change to the migration guide does not reflect an actual API change but rather the availability of new sample code for uploading videos with client-side JavaScript.
Given the support for uploading videos with the JavaScript client library and CORS, the migration guide no longer lists browser-based uploading as a feature that may be deprecated in the v3 API.
The documentation for the videos.insert method has been updated to include the new JavaScript code sample described above. The list of JavaScript code samples for the YouTube Data API (v3) has also been updated.

November 11, 2014

This update contains the following changes:

The quota cost for a call to the search.list method has changed to 100 units.
Important: In many cases, you can use other API methods to retrieve information at a lower quota cost. For example, consider these two ways of finding videos uploaded to the GoogleDevelopers channel.
- Quota cost: 100 units
  Call the search.list method and search for GoogleDevelopers .
- Quota cost: 6 units
  Call the channels.list method to find the right channel ID. Set the forUsername parameter to GoogleDevelopers and the part parameter to contentDetails . In the API response, the contentDetails.relatedPlaylists.uploads property specifies the playlist ID for the channel's uploaded videos.
  Then call the playlistItems.list method and set the playlistId parameter to the captured ID and the part parameter to snippet .

8 اکتبر 2014

This update contains the following changes:

The channel resource contains two new properties:
- The status.longUploadsStatus property indicates whether the channel is eligible to upload videos that are more than 15 minutes long. This property is only returned if the channel owner authorized the API request. Valid property values are:
  - allowed – The channel can upload videos more than 15 minutes long.
  - eligible – The channel is eligible to upload videos more than 15 minutes long but must first enable the feature.
  - disallowed – The channel is not able or eligible to upload videos more than 15 minutes long.
  See the property definition for more information about these values. The YouTube Help Center also provides more detailed information about this feature.
- The invideoPromotion.useSmartTiming property indicates whether the channel's promotional campaign uses "smart timing." This feature attempts to show promotions at a point in the video when they are more likely to be clicked and less likely to disrupt the viewing experience. This feature also picks up a single promotion to show on each video.
The definitions of the video resource's snippet.title and snippet.categoryId properties have both been updated to clarify the way that API handles calls to the videos.update method. If you call that method to update the snippet part of a video resource, you must set a value for both of those properties.
If you try to update the snippet part of a video resource and do not set a value for both of those properties, the API returns an invalidRequest error. That error's description has also been updated.
The video resource's contentDetails.contentRating.oflcRating property, which identifies a video's rating from New Zealand's Office of Film and Literature Classification, now supports two new ratings: oflcRp13 and oflcRp16 . These correspond to the RP13 and RP16 ratings, respectively.

The channelBanners.insert method now supports the following error:

نوع خطا	جزئیات خطا	شرح
`badRequest`	`bannerAlbumFull`	The channel owner's YouTube Channel Art album has too many images. The channel owner should go to http://photos.google.com , navigate to the albums page, and remove some from images from that album.

12 سپتامبر 2014

This update contains the following changes:

The quota cost for a call to the search.list method has changed from 1 unit to 2 units in addition to the cost of the specified resource parts .

13 آگوست 2014

This update contains the following changes:

The subscriptions.insert method now supports the following error:

نوع خطا	جزئیات خطا	شرح
`badRequest`	`subscriptionLimitExceeded`	The subscriber identified with the request has exceeded the subscription rate limit. More subscriptions can be attempted in a few hours.

12 آگوست 2014

This update contains the following changes:

A new guide, titled Migrating Your Application to YouTube Data API (v3) , explains how to use the YouTube Data API (v3) to perform functionality available in the YouTube Data API (v2). The older API was officially deprecated as of March 4, 2014. The guide intends to help you migrate applications still using the v2 API to the most recent API version.

8 جولای 2014

This update contains the following changes:

The playlists.insert method now supports the following error:
نوع خطا جزئیات خطا شرح
badRequest maxPlaylistExceeded This error occurs if a playlist cannot be created because the channel already has the maximum number of playlists allowed.

18 ژوئن 2014

This update contains the following changes:

The description of each API method has been updated to include the quota cost incurred by a call to that method. Similarly, the definitions of part parameters have been updated to specify the quota cost of each part that can be retrieved in an API call. For example, a call to the subscriptions.insert method has a quota cost of approximately 50 units. The subscription resource also contains three parts ( snippet , contentDetails , and subscriberSnippet ), and each of those has a cost of two units.
Please remember that quota costs can change without warning.
The video resource now supports 43 new content rating systems, which identify the ratings that videos received from various national rating agencies. The newly supported rating systems are from Argentina , Austria , Belgium , Bulgaria , Chile ( television ), Chile ( film ), Czech Republic , Colombia , Denmark , Egypt , Estonia , Finland , France , Greece , Hong Kong , Iceland , Indonesia , Ireland , Israel , Italy , Kenya , Latvia , Luxembourg , Malaysia , Maldives , Malta , Netherlands , Nigeria , Norway , Peru , Philippines , Portugal , Romania , Singapore , Slovakia , South Africa , Sweden , Switzerland , Taiwan , Thailand , and Venezuela .

28 مه 2014

This update contains the following changes:

The search.list method now supports the location and locationRadius parameters, which let you search for videos associated with a geographic location. A request must specify a value for both parameters to retrieve results based on location, and the API will return an error if a request includes only one of the two parameters.
- The location parameter specifies the latitude/longitude coordinates at the center of the circular geographic area.
- The locationRadius parameter specifies the maximum distance that the location associated with a video can be from the center of the area for the video to still be included in search results.

13 مه 2014

This update contains the following changes:

The channel resource's invideoPromotion.items[] property has been updated to note that you can typically only set one promoted item for your channel. If you try to insert too many promoted items, the API will return a tooManyPromotedItems error, which has an HTTP 400 status code.
The channelSection resource now can contain information about a few new types of featured content. The channelSection resource's snippet.type property now supports the following values:
- postedPlaylists - playlists that the channel's owner posted to the channel's activity feed
- postedVideos - videos that the channel's owner posted to the channel's activity feed
- subscriptions - channels that the channel owner has subscribed to
The video resource's new contentDetails.contentRating.ifcoRating property identifies the rating that a video received from the Irish Film Classification Office.
The definition of the watermark resource's position.cornerPosition property has been updated to note that the watermark always appear in the upper right corner of the player.
The definition of the q parameter for the search.list method has been updated to note that the query term can use the Boolean NOT ( - ) operator to exclude videos associated with a particular search term. The value can also use the Boolean OR ( | ) operator to find videos associated with one of several search terms.
The definition of the pageInfo.totalResults property that is returned in an API response to a search.list call has been updated to note that the value is an approximation and may not represent an exact value. In addition, the maximum value is 1,000,000. You should not use this value to create pagination links. Instead, use the nextPageToken and prevPageToken property values to determine whether to show pagination links.
The watermarks.set and watermarks.unset methods have been updated to reflect that the API returns an HTTP 204 response code for successful requests to those methods.

2 مه 2014

This update contains the following changes:

The new i18nLanguage resource identifies an application language that the YouTube website supports. The application language can also be referred to as a UI language. For the YouTube website, an application language could be automatically selected based on Google Account settings, browser language, or IP location, and a user could also manually select the desired UI language from the YouTube site footer.
The API supports a method to list supported application languages. Supported languages can be used as the value of the hl parameter when calling API methods like videoCategories.list and guideCategories.list .
The new i18nRegion resource identifies a geographic area that a YouTube user can select as the preferred content region. The content region can also be referred to as a content locale. For the YouTube website, a content region could be automatically selected based on heuristics like the YouTube domain or the user's IP location, and a user could also manually select the desired content region from the YouTube site footer.
The API supports a method to list supported content regions. Supported region codes can be used as the value of the regionCode parameter when calling API methods like search.list , videos.list , activities.list , and videoCategories.list .

7 آوریل 2014

This update contains the following changes:

The new channelSection resource contains information about a set of videos that a channel has chosen to feature. For example, a section could feature a channel's latest uploads, most popular uploads, or videos from one or more playlists.
The API supports methods to list , insert , update , or delete channel sections. You can retrieve a list of channel sections for the authenticated user's channel, by specifying a particular channel ID, or by specifying a list of unique channel section IDs.
The error documentation has also been updated to describe the error messages that the API supports specifically for these new methods.
The definition of the video resource's fileDetails object has been updated to explain that that object will only be returned if the video's processingDetails.fileDetailsAvailability property has a value of available .
Similarly, the definition of the video resource's suggestions object has been updated to explain that that object will only be returned if the video's processingDetails.tagSuggestionsAvailability property or its processingDetails.editorSuggestionsAvailability property has a value of available .
The documentation for the videos.insert and videos.update methods has been updated to reflect that the status.publishAt property can be set when calling those methods.
The definition of the channel resource's invideoPromotion object has been updated to explain that the object can only be retrieved by the channel's owner.
The parameter list for the videos.rate method has been updated to reflect that that method does not actually support the onBehalfOfContentOwner parameter. This was a documentation error as videos.rate requests that set this parameter return a 500 error.

31 مارس 2014

This update contains the following changes:

The video resource's new status.publishAt property lets you specify the date and time when a private video is scheduled to be published. This property can only be set if the video's privacy status is private and the video has never been published. This new property is not subject to the deprecation policy .

13 مارس 2014

This update contains the following changes:

The API now supports the contentOwnerDetails part for channel resources. The new part contains channel data that is relevant for YouTube partners linked with the channel, including the ID of the content owner linked to the channel and the date and time when the content owner and channel were linked. Note that this new part is not subject to the deprecation policy .

The documentation now lists the maximum supported character length for the following properties:

منبع	ویژگی	حداکثر طول
`channel`	`invideoPromotion.items[].customMessage`	40 characters
`video`	`snippet.title`	100 characters
`video`	`snippet.description`	5000 bytes
`video`	`snippet.tags`	500 characters. Note that the property value is a list and that commas between items in the list count toward the limit.

The channel resource's brandingSettings.watch.featuredPlaylistId property has been deprecated. The API will return an error if you attempt to set its value.
The following video resource properties have been added to the list of values that can be set when inserting or updating a video:
The error documentation now specifies the HTTP response code for each error type.

The API now supports the following errors:

نوع خطا	جزئیات خطا	شرح
`badRequest (400)`	`invalidCriteria`	The `channels.list` method returns this error if the request specifies filter parameters that cannot be used in conjunction with each other.
`badRequest (400)`	`channelTitleUpdateForbidden`	The `channels.update` method returns this error if you attempt to update a channel's `brandingSettings` part and change the value of the `brandingSettings.channel.title` property. (Note that the API does not return the error if you omit the property.)
`badRequest (400)`	`invalidRecentlyUploadedBy`	The `channels.update` method returns this error if the `invideoPromotion.items[].id.recentlyUploadedBy` property specifies an invalid channel ID.
`badRequest (400)`	`invalidTimingOffset`	The `channels.update` method returns this error if the `invideoPromotion` part specifies an invalid timing offset.
`badRequest (400)`	`tooManyPromotedItems`	The `channels.update` method returns this error if the `invideoPromotion` part specifies more than the allowed number of promoted items.

This update contains the following changes:

The YouTube Data API, v3 is now subject to the Deprecation Policy described in the YouTube APIs Terms of Service . Note that the page that lists the APIs that are subject to the deprecation policy specifically excludes some v3 API functionality from being subject to the policy.

5 دسامبر 2013

This update contains the following changes:

The search.list method's documentation has been updated to properly reflect that you do not need to specify a value for exactly one filter parameter when submitting a search request. Rather, you can set a value for zero filter parameters or for one filter parameter.
The definitions for the search.list method's parameters have been updated to note that you must set the type parameter's value to video if you also specify a value for any of the following parameters:
- eventType
- videoCaption
- videoCategoryId
- videoDefinition
- videoDimension
- videoDuration
- videoEmbeddable
- videoLicense
- videoSyndicated
- videoType
The minimum size of uploaded channel banner images has been reduced to 2048px by 1152px. (Previously, the minimum size was 2120px by 1192px.) In addition, note that the channel resource documentation specifies the maximum sizes of all of the banner images served from the API. For example, the maximum size of the brandingSettings.image.bannerTvImageUrl image for television applications is 2120px by 1192px, but the actual image may be 2048px by 1152px. The YouTube Help Center provides additional guidance for optimizing channel art for display on different types of devices.
Several channel resource property definitions have been updated to reflect the following information:
- The brandingSettings.channel.description property's value has a maximum length of 1000 characters.
- The brandingSettings.channel.featuredChannelsTitle property has a maximum length of 30 characters.
- The brandingSettings.channel.featuredChannelsUrls[] property can now list up to 100 channels.
- The brandingSettings.channel.unsubscribedTrailer property value, if set, must specify the YouTube video ID of a public or unlisted video that is owned by the channel owner.
The channels.update method now supports updates to the invideoPromotion.items[].promotedByContentOwner property. That property indicates whether the content owner's name will be shown when displaying the promotion. It can only be set if the API request that sets the property value is being made on the content owner's behalf using the onBehalfOfContentOwner parameter.
The playlistItems.list and playlistItems.insert methods now support the onBehalfOfContentOwner parameter, which is already supported for several other methods.
The contentDetails.contentRating.acbRating property can now specify a rating from either the Australian Classification Board (ACB) for movies or from the Australian Communications and Media Authority (ACMA) for children's television programming.
The new contentDetails.contentRating.catvRating and contentDetails.contentRating.catvfrRating properties identify the ratings that a video received under the Canadian TV Classification System and the French-language Régie du cinéma rating system, which is used in Québec, respectively.
The videoCategory resource's new snippet.assignable property indicates whether updated videos or newly uploaded videos can be associated with that video category.
Code samples have been added for the following methods:
- activities.insert (Go)
- channelBanners.insert (Python)
- channels.update (Python)
- playlistItems.list (Go)
- search.list (Go)
- thumbnails.set (Java)
- videos.insert (Go)

24 اکتبر 2013

This update contains the following changes:

The API includes two additional features designed to help find and feature live broadcast content:
The new snippet.liveBroadcastContent property in search results indicates whether a video or channel resource has live broadcast content. Valid property values are upcoming , active , and none .
- The video resource's new snippet.liveBroadcastContent property indicates whether the video is an upcoming or active live broadcast. The list below explains the property's possible values:
  - upcoming – The video is a live broadcast that has not yet started.
  - active – The video is an ongoing live broadcast.
  - none – The video is not an upcoming or active live broadcast. This will be the property value for completed broadcasts that are still viewable on YouTube.
- The video resource's new liveStreamingDetails property is an object that contains metadata about a live video broadcast. To retrieve this metadata, include liveStreamingDetails in the part parameter value's list of resource parts. The metadata includes the following new properties:
  - liveStreamingDetails.actualStartTime – The time that the broadcast actually started. (This value will be present once the broadcast's state is active .)
  - liveStreamingDetails.actualEndTime – The time that the broadcast actually ended. (This value will be present once the broadcast is over.)
  - liveStreamingDetails.scheduledStartTime – The time that the broadcast is scheduled to begin.
  - liveStreamingDetails.scheduledEndTime – The time that the broadcast is scheduled to end. If the property value is empty or the property is not present, then the broadcast is scheduled to go on indefinitely.
  - liveStreamingDetails.concurrentViewers – The number of people watching the live broadcast.
  To retrieve this metadata, include liveStreamingDetails in the part parameter value when calling the videos.list , videos.insert , or videos.update method.
Note that two other features for identifying live broadcast content were released on October 1, 2013 – the search.list method's eventType parameter and the search result's snippet.liveBroadcastContent property.
The videos.insert method now supports the notifySubscribers parameter, which indicates whether YouTube should send a notification about the new video to users who subscribe to the video's channel. The parameter's default value is True , which indicates that subscribers will be notified of newly uploaded videos. However, a channel owner who is uploading many videos might prefer to set the value to False to avoid sending a notification about each new video to the channel's subscribers.
The list of properties that can be modified when calling the channels.update method has been updated to include the invideoPromotion.items[].customMessage and invideoPromotion.items[].websiteUrl properties. In addition, the list has been modified to identify the brandingSettings properties that are modifiable. These brandingSettings properties were already modifiable, so the documentation change does not reflect a change to the API's existing functionality.
The playlists.insert , playlists.update , and playlists.delete methods now support the onBehalfOfContentOwner parameter, which is already supported for several other methods.
The playlists.insert method now supports the onBehalfOfContentOwnerChannel parameter, which is already supported for several other methods.
The video resource's contentDetails.contentRating.tvpgRating property now supports a value of pg14 , which corresponds to a TV-14 rating.
The definition of the snippet.liveBroadcastContent property, which is part of search results, has been corrected to reflect that live is a valid property value, but active is not a valid property value.
The video resource's contentDetails.contentRating.mibacRating property now supports two additional ratings:
- mibacVap (VAP) – Children should be accompanied by an adult.
- mibacVm6 (VM6) – Restricted to 6 and over.
- mibacVm12 (VM12) – Restricted to 12 and over.
The channel resource's new invideoPromotion.items[].promotedByContentOwner property indicates whether the content owner's name will be shown when displaying the promotion. This field can only be set if the API request that sets the value is being made on the content owner's behalf. See the onBehalfOfContentOwner parameter for more information.

1 اکتبر 2013

This update contains the following changes:

The channel resource's new auditDetails object contains channel data that a multichannel network (MCN) would evaluate while determining whether to accept or reject a particular channel. Note that any API request that retrieves this resource part must provide an authorization token that contains the https://www.googleapis.com/auth/youtubepartner-channel-audit scope. In addition, any token that uses that scope must be revoked when the MCN decides to accept or reject the channel or within two weeks of the date that the token was issued.
The channel resource's invideoPromotion.items[].id.type property now supports a value of recentUpload , which indicates that the promoted item is the most recently uploaded video from a specified channel.
By default, the channel is the same as the one for which the in-video promotion data is set. However, you can promote the most recently uploaded video from another channel by setting the value of the new invideoPromotion.items[].id.recentlyUploadedBy property to the channel ID for that channel.
The channel resource contains three new properties – brandingSettings.image.bannerTvLowImageUrl , brandingSettings.image.bannerTvMediumImageUrl , brandingSettings.image.bannerTvHighImageUrl – that specify the URLs for the banner images that display on channel pages in television applications.
The new snippet.liveBroadcastContent property in search results indicates whether a video or channel resource has live broadcast content. Valid property values are upcoming , active , and none .
- For a video resource, a value of upcoming indicates that the video is a live broadcast that has not yet started, while a value of active indicates that the video is an ongoing live broadcast.
- For a channel resource, a value of upcoming indicates that the channel has a scheduled broadcast that has not yet started, while a value of acive indicates that the channel has an ongoing live broadcast.
In the watermark resource, the targetChannelId property has changed from an object to a string. Instead of containing a child property that specifies the YouTube channel ID of the channel that the watermark image links to, the targetChannelId property now specifies that value itself. Accordingly, the resource's targetChannelId.value property has been removed.
The thumbnails.set method now supports the onBehalfOfContentOwner parameter, which is already supported for several other methods.
The search.list method now supports the eventType parameter, which restricts a search to only return either active, upcoming, or completed broadcast events.
The new contentDetails.contentRating.mibacRating property identifies the rating that a video received from Italy's Ministero dei Beni e delle Attivita Culturali e del Turismo.

The API now supports the following errors:

نوع خطا	جزئیات خطا	شرح
`badRequest`	`invalidImage`	The `thumbnails.set` method returns this error if the provided image content is invalid.
`forbidden`	`videoRatingDisabled`	The `videos.rate` method returns this error if the owner of the video that is being rated has disabled ratings for that video.

August 27, 2013

This update contains the following changes:

The new watermark resource identifies an image that displays during playbacks of a specified channel's videos. You can also specify a target channel to which the image will link as well as timing details that determine when the watermark appears during video playbacks and the length of time it is visible.
The watermarks.set method uploads and sets a channel's watermark image. The watermarks.unset method deletes a channel's watermark image.
The error documentation describes the error messages that the API supports specifically for the watermarks.set and watermarks.unset methods.
The channel resource's new statistics.hiddenSubscriberCount property contains a boolean value that indicates whether the channel's number of subscribers is hidden. As such, the property's value is false if the channel's subscriber count is publicly visible.
The playlists.list method now supports the onBehalfOfContentOwner and onBehalfOfContentOwnerChannel parameters. Both parameters are already supported for several other methods.
The videos.list method now supports the regionCode parameter, which identifies the content region for which a chart should be retrieved. This parameter can only be used in conjunction with the chart parameter. The parameter value is an ISO 3166-1 alpha-2 country code.
The error documentation describes the following new common request error, which could occur for multiple API methods:
نوع خطا جزئیات خطا شرح
forbidden insufficientPermissions The scopes associated with the OAuth 2.0 token provided for the request are insufficient for accessing the requested data.

15 آگوست 2013

This update contains the following changes:

The channel resource's invideoPromotion object has the following new and updated properties:
- The API now supports the ability to specify a website as a promoted item. To do so, set the invideoPromotion.items[].id.type property value to website and use the new invideoPromotion.items[].id.websiteUrl property to specify the URL. Also use the new invideoPromotion.items[].customMessage property to define a custom message to display for the promotion.
  Links can be to associated websites, merchant sites, or social networking sites. See the YouTube Help Center instructions for associated websites and merchant sites for more information about enabling links for your content.
  By adding promotional links, you agree that those links will not be used to redirect traffic to unauthorized sites and that those links will comply with YouTube's AdWords policies , YouTube ad policies , YouTube Community Guidelines and YouTube Terms of Service .
- The properties related to the timing settings for displaying promoted items during video playback have been restructured:
  - The invideoPromotion.timing object has been moved to invideoPromotion.items[].timing . This object now enables you to customize the timing data for each promoted item in the invideoPromotion.items[] list.
  - The new invideoPromotion.defaultTiming object specifies default timing settings for your promotion. Those settings define when a promoted item will display during playback of one of your channel's videos. You can override the default timing for any given promoted item using the invideoPromotion.items[].timing object.
  - The new invideoPromotion.items[].timing.durationMs property specifies the amount of time, in milliseconds, that the promotion should display. The invideoPromotion.defaultTiming object also contains a durationMs field that specifies the default amount of time that the promoted item will display.
- The invideoPromotion.items[].type and invideoPromotion.items[].videoId properties both have been moved into the invideoPromotion.items[].id object.
The subscriptions.list method now supports the onBehalfOfContentOwner and onBehalfOfContentOwnerChannel parameters. Both parameters are already supported for several other methods.
In the API response to a thumbnails.set request, the kind property value has changed from youtube#thumbnailListResponse to youtube#thumbnailSetResponse .
Code samples have been added for the following methods:
- channels.update (Java, Python)
- playlists.insert (.NET, PHP)
- subscriptions.insert (PHP, Python)
- thumbnails.set (PHP, Python)
- videos.insert (PHP)
- videos.list (PHP)
- videos.rate (Python)
- videos.update (Java, PHP, Python)
Note that the Python example for the playlistItems.insert method was also removed since the functionality it demonstrated is now handled by the videos.rate method.

The error documentation describes the following new request context error, which could occur for any API method that supports the mine request parameter:

نوع خطا	جزئیات خطا	شرح
`badRequest`	`invalidMine`	The `mine` parameter cannot be used in requests where the authenticated user is a YouTube partner. You should either remove the `mine` parameter, authenticate as a YouTube user by removing the `onBehalfOfContentOwner` parameter, or act as one of the partner's channels by providing the `onBehalfOfContentOwnerChannel` parameter if available for the called method.

8 آگوست 2013

This update contains the following changes:

The Getting Started with the YouTube Data API guide's Quota Usage section has been updated to reflect a change in the quota cost of a video upload from approximately 16000 units to approximately 1600 units.

30 جولای 2013

This update contains the following changes:

In a channelBanner resource, the value of the kind property's value has changed from youtube#channelBannerInsertResponse to youtube#channelBannerResource . This resource is returned in response to a channelBanners.insert request.
The channel resource's new brandingSettings.channel.profileColor property specifies a prominent color that complements the channel's content. The property value is a pound sign ( # ) followed by a six-character hexadecimal string, such as #2793e6 .
The API now supports the ability to specify whether a subscription is for all of a channel's activities or just for new uploads. The subscription resource's new contentDetails.activityType property identifies the types of activities that the subscriber will be notified about. Valid property values are all and uploads .
The videos.list method supports new parameters for retrieving a chart of the most popular videos on YouTube:
- The chart parameter identifies the chart that you want to retrieve. Currently, the only supported value is mostPopular . Note that the chart parameter is a filter parameter, which means it cannot be used in the same request as other filter parameters ( id and myRating ).
- The videoCategoryId parameter identifies the video category for which the chart should be retrieved. This parameter can only be used in conjunction with the chart parameter. By default, charts are not restricted to a particular category.
The video resource's new topicDetails.relevantTopicIds[] property provides a list of Freebase topic IDs that are relevant to the video or its content. The subjects of these topics may be mentioned in or appear in the video.
The video resource's recordingDetails.location.elevation property has been renamed to recordingDetails.location.altitude , and its fileDetails.recordingLocation.location.elevation property has been renamed to fileDetails.recordingLocation.location.altitude .
The video resource's contentDetails.contentRating object specifies the ratings that a video received under various rating schemes, including MPAA ratings, TVPG ratings, and so forth. For each rating system, the API now supports a rating value that indicates that the video has not been rated. Note that for MPAA ratings , an "unrated" rating is frequently used to identify uncut versions of films for which the cut version of the film did receive an official rating.
The video resource's new contentDetails.contentRating.ytRating property identifies age-restricted content. The property value will be ytAgeRestricted if YouTube has identified the video as containing content that is inappropriate for users less than 18 years old. If the property is absent or if the property value is empty, then the content has not been identified as age-restricted.
The channels.list method's mySubscribers parameter has been deprecated. Use the subscriptions.list method and its mySubscribers parameter to retrieve a list of subscribers to the authenticated user's channel.
The channelBanners.insert , channels.update , videos.getRating , and videos.rate methods all now support the onBehalfOfContentOwner parameter. That parameter indicates that the authenticated user is acting on behalf of the content owner specified in the parameter value.
The channels.update method's documentation has been updated to reflect the fact that that method can be used to update the channel resource's brandingSettings object and its child properties. The documentation also now lists the updated list of properties that you can set for the channel resource's invideoPromotion object.

The error documentation describes the following new errors:

نوع خطا	جزئیات خطا	شرح
`forbidden`	`accountDelegationForbidden`	This error is not specific to a particular API method. It indicates that the authenticated user is not authorized to act on behalf of the specified Google account.
`forbidden`	`authenticatedUserAccountClosed`	This error is not specific to a particular API method. It indicates that the authenticated user's YouTube account is closed. If the user is acting on behalf of another Google Account, then this error would indicate that that other account is closed.
`forbidden`	`authenticatedUserAccountSuspended`	This error is not specific to a particular API method. It indicates that the authenticated user's YouTube account is suspended. If the user is acting on behalf of another Google Account, then this error would indicate that that other account is suspended.
`forbidden`	`authenticatedUserNotChannel`	This error is not specific to a particular API method. It indicates that the API server cannot identify the channel associated with the API request. If the request is authorized and uses the `onBehalfOfContentOwner` parameter, you should also set the `onBehalfOfContentOwnerChannel` parameter.
`forbidden`	`cmsUserAccountNotFound`	This error is not specific to a particular API method. The CMS user is not allowed to act on behalf of the specified content owner.
`notFound`	`contentOwnerAccountNotFound`	This error is not specific to a particular API method. The specified content owner account was not found.
`badRequest`	`invalidPart`	This error is not specific to a particular API method. The request's `part` parameter specifies parts that cannot be written at the same time.
`badRequest`	`videoChartNotFound`	The `videos.list` method returns this error when the request specifies an unsupported or unavailable video chart.
`notFound`	`videoNotFound`	The `videos.update` method returns this error to indicate that the video you are trying to update cannot be found. Check the value of the `id` property in the request body to ensure it is correct.

10 ژوئن 2013

This update contains the following changes:

The channels.list method's new forUsername parameter enables you to retrieve information about a channel by specifying its YouTube username.
The activities.list method now supports the regionCode parameter, which instructs the API to return results relevant to the specified country. YouTube uses this value when the authorized user's previous activity on YouTube does not provide enough information to generate the activity feed.
Playlist resources now contain the snippet.tags property. The property will be only be returned to authorized users who are retrieving data about their own playlists. Authorized users can also set playlist tags when calling either the playlists.insert or playlists.update methods.
The onBehalfOfContentOwner parameter, which was previously supported for the channels.list and search.list methods, is now also supported for the videos.insert , videos.update , and videos.delete methods. Note that when this parameter is used in a call to the videos.insert method, the request must also specify a value for the new onBehalfOfContentOwnerChannel parameter, which identifies the channel to which the video will be added. The channel must be linked to the content owner that the onBehalfOfContentOwner parameter specifies.
The parameter indicates that the request's authorization credentials identify a YouTube CMS user who is acting on behalf of the content owner specified in the parameter value. The CMS account that the user authenticates with must be linked to the specified YouTube content owner.
This parameter is intended for content partners that own and manage many different YouTube channels. The parameter enables those partners to authenticate once and get access to all of their video and channel data, without having to provide authentication credentials for each individual channel.
Specifically in regard to this release, the parameter now enables a content partner to insert, update, or delete videos in any of the YouTube channels that the partner owns.

The error documentation describes the following new errors:

نوع خطا	جزئیات خطا	شرح
`forbidden`	`insufficientCapabilities`	This error is not specific to a particular API method. It indicates that the CMS user calling the API does not have sufficient permissions to perform the requested operation. This error is associated with the use of the `onBehalfOfContentOwner` parameter, which is supported for several API methods.
`unauthorized`	`authorizationRequired`	The `activities.list` method returns this error when the request uses the `home` parameter but is not properly authorized.

In the channels resource, the invideoPromotion.channelId property has been removed because the channel ID is already specified using the resource's id property.
The new Working with Channel IDs guide explains how the API uses channel IDs. The guide may be especially useful for developers migrating from the previous version of the API and who have applications that either request content for the default user or that rely on the notion that every YouTube channel has a unique username, which is no longer the case.

22 مه 2013

This update contains the following changes:

The new channelBanners.insert method enables you to upload a banner image that can subsequently be set as the banner image for a channel using the channel resource's new brandingSettings.image.bannerExternalUrl property.
The documentation for the channels.update method has been updated to list the properties that can be modified when calling the method.
The video resource documentation no longer lists unspecified as a valid property value for the suggestions.processingErrors[] , suggestions.processingHints[] , suggestions.processingWarnings[] , and suggestions.editorSuggestions[] properties.
The videos.list method's maxResults parameter now has a default value of 5 .
The error documentation now lists errors for the channelBanners.insert and subscriptions.list methods. It also lists several new errors for the channels.update method.

May 14, 2013

This update contains the following changes:

Standalone pages now list code samples for Java , .NET , PHP , and Ruby .
The page that lists Python code samples now includes examples for adding a subscription, creating a playlist, and updating a video.

10 مه 2013

This update contains the following changes:

YouTube no longer identifies experimental API features and services. Instead, we now provide a list of YouTube APIs that are subject to the deprecation policy .

8 مه 2013

This update contains the following changes:

Channel resources now support the inVideoPromotion object, which encapsulates information about a promotional campaign associated with the channel. A channel can use an in-video promotional campaign to display thumbnail images for a promoted video within the video player during playbacks of the channel's videos.
You can retrieve this data by including invideoPromotion in the part parameter value in a channels.list request.
The new channels.update method can be used to update a channel's in-video promotional campaign data. Note that the method only supports updates to the invideoPromotion part of the channel resource and does not yet support updates to other parts of that resource.

2 مه 2013

This update contains the following changes:

Channel resources now support the status.isLinked property, which indicates whether the channel data identifies a user that is already linked to either a YouTube username or a Google+ account. A user that has one of these links already has a public YouTube identity, which is a prerequisite for several actions, such as uploading videos.
Subscription resources now support the subscriberSnippet part. That object encapsulates contains snippet data for the subscriber's channel.
The API now supports the videos.getRating method, which retrieves the ratings that the authenticated user gave to a list of one or more videos.
The videos.list method's new myRating parameter enables you to retrieve a list of videos that the authenticated user rated with a like or dislike rating.
The myRating parameter and the id parameter are both now considered filter parameters, which means that an API request must specify exactly one of the parameters. (Previously, the id parameter was a required parameter for this method.)
The method returns a forbidden error for requests that attempt to retrieve video rating information but are not properly authorized to do so.
With the introduction of the myRating parameter, the videos.list method has also been updated to support pagination. Note, however, that paging parameters are only supported for requests using the myRating parameter. (Paging parameters and information are not supported for requests that use the id parameter.)
- The maxResults parameter specifies the maximum number of videos that the API can return in the result set, and the pageToken parameter identifies a specific page in the result set that you want to retrieve.
- The youtube#videoListResponse resource, which is returned in response to a videos.list request, now contains the pageInfo object, which contains details like the total number of results and the number of results included in the current result set. The youtube#videoListResponse resource can also include nextPageToken and prevPageToken properties, each of which provides a token that could be used to retrieve a specific page in the result set.
The videos.insert method supports the following new parameters:
- autoLevels – Set this parameter value to true to instruct YouTube to automatically enhance the video's lighting and color.
- stabilize – Set this parameter value to true to instruct YouTube to adjust the video by removing shakiness resulting from camera motions.
The channelTitle property has been added to the snippet for the following resources:
- playlistItem – The property specifies the name of the channel that added the playlist item.
- playlist – The property specifies the name of the channel that created the playlist.
- subscription – The property specifies the name of the channel that is subscribed to.
Code samples have been added for the following methods:
- activities.insert (Ruby)
- playlistItems.list (.NET)
- search.list (.NET)
- subscriptions.insert (Java, Ruby)
- videos.insert (.NET, Ruby)
The subscriptions.list method's new mySubscribers parameter enables you to retrieve a list of the currently authenticated user's subscribers. This parameter can only be used in a properly authorized request.
Note: This functionality is intended to replace the mySubscribers parameter currently supported for the channels.list method. That parameter will be deprecated.
In a video resource, the property value unspecified is no longer a possible value for any of the following properties:
API requests that contain an unexpected parameter now return a badRequest error, and the reported reason for the error is unexpectedParameter .
The error that the playlistItems.insert method returns when the playlist already contains the maximum number of allowed items has been updated. The error is now reported as a forbidden error, and the error reason is playlistContainsMaximumNumberOfVideos .

19 آوریل 2013

This update contains the following changes:

The new videos.rate method lets a user set a like or dislike rating on a video or remove a rating from a video.
The error documentation has also been updated to list the errors that the API might return in response to a videos.rate method call.
Thumbnail images are now identified in the API documentation as a separate resource , and the new thumbnails.set method enables you to upload a custom video thumbnail to YouTube and set it for a video.
The error documentation has also been updated to list the errors that the API might return in response to a thumbnails.set method call.
Note that this change does not really affect existing resources that return thumbnail images. Thumbnail images are returned in those resources in the same way that they were previously, though the documentation does now list the names of the different thumbnail sizes that the API might return.
The channel resource's new brandingSettings part identifies settings, text, and images for the channel's channel page and video watch pages.
The playlistItem resource contains the following new properties:
- The new status object encapsulates status information about the playlist item, and the status.privacyStatus property identifies the playlist item's privacy status.

The video resource contains the following new properties:

The status.publicStatsViewable property indicates whether extended video statistics on the watch page are publicly viewable. By default, those statistics are viewable, and statistics like a video's viewcount and ratings will still be publicly visible even if this property's value is set to false . You can set this property's value when calling the videos.insert or videos.update method.

The playlistItems.update method's documentation has been updated to reflect the fact that the snippet.resourceId property must be specified in the resource sent as the request body.
The search.list method now supports the following functionality:
- The new forMine parameter restricts a search to only retrieve the authenticated user's videos.
- The order parameter now supports the ability to sort results alphabetically by title ( order=title ) or by video count in descending order ( order=videoCount ).
- The new safeSearch parameter indicates whether search results should include restricted content.

The videos.insert method supports several new errors, which are listed in the table below:

نوع خطا	جزئیات خطا	شرح
`badRequest`	`invalidCategoryId`	The `snippet.categoryId` property specifies an invalid category ID. Use the `videoCategories.list` method to retrieve supported categories.
`badRequest`	`invalidRecordingDetails`	The `metadata specifies invalid recording details.`
`badRequest`	`invalidVideoGameRating`	The request metadata specifies an invalid video game rating.
`badRequest`	`invalidVideoMetadata`	The request metadata is invalid.

The onBehalfOfContentOwner parameter has been removed from the list of supported parameters for the videos.update and videos.delete methods.

This update contains the following changes:

The channelTitle property has been added to the snippet for the following resources:
- activity – The property specifies the name of the channel responsible for the activity.
- search – The property specifies the name of the channel associated with the resource that the search result identifies.
- video – The property specifies the name of the channel that uploaded the video.
The search.list method supports the following new parameters:
- The channelType parameter lets you restrict a search for channels to retrieve all channels or to retrieve only shows.
- The videoType parameter lets you restrict a search for videos to retrieve all videos or to retrieve only movies or only episodes of shows.
The definition of the video resource's recordingDetails part has been updated to note that the object will only be returned for a video if the video's geolocation data or recording time has been set.
The playlistItems.update method now returns an invalidSnippet error, which is returned if the API request does not specify a valid snippet.
Several API methods support new parameters that are intended exclusively for YouTube content partners. YouTube content partners include movie and television studios, record labels, and other content creators that make their content available on YouTube.
- پارامتر onBehalfOfContentOwner نشان می دهد که اعتبارنامه مجوز درخواست، کاربر YouTube CMS را شناسایی می کند که از طرف مالک محتوا مشخص شده در مقدار پارامتر عمل می کند. The CMS account that the user authenticates with must be linked to the specified YouTube content owner.
  This parameter is intended for content partners that own and manage many different YouTube channels. The parameter enables those partners to authenticate once and get access to all of their video and channel data, without having to provide authentication credentials for each individual channel.
  The channels.list , search.list , videos.delete , videos.list , and videos.update methods all support this parameter.
- The managedByMe parameter, which is supported by the channels.list method, instructs the API to return all channels owned by the content owner that the onBehalfOfContentOwner parameter specifies.
- The forContentOwner parameter, which is supported by the search.list method, instructs the API to restrict search results to only include resources that are owned by the content owner that the onBehalfOfContentOwner parameter specifies.

This update contains the following changes:

The API supports several new parts and properties for video resources:
- The new fileDetails , processingDetails , and suggestions parts provide information to video owners about their uploaded videos. This data is very useful in applications that enable video uploads and includes the following:
  - processing status and progress
  - errors or other issues encountered while processing a video
  - availability of thumbnail images
  - suggestions for improving video or metadata quality
  - details about the original file uploaded to YouTube
  All of these parts can only be retrieved by the video owner. The list below briefly describes the new parts, and the video resource documentation defines all of the properties that each part contains.
  - The fileDetails object contains information about the video file that was uploaded to YouTube, including the file's resolution, duration, audio and video codecs, stream bitrates, and more.
  - The processingProgress object contains information about YouTube's progress in processing the uploaded video file. The object's properties identify the current processing status and estimate the time remaining until YouTube finishes processing the video. This part also indicates whether different types of data or content, such as file details or thumbnail images, are available for the video.
    This object is designed to be polled so that the video uploader can track the progress that YouTube has made in processing the uploaded video file.
  - The suggestions object contains suggestions that identify opportunities to improve the video quality or the metadata for the uploaded video.
- The contentDetails part contains four new properties. These properties can be retrieved with unauthenticated requests.
  - dimension – Indicates whether the video is available in 2D or 3D.
  - definition – Indicates whether the video is available in standard or high definition.
  - caption – Indicates whether captions are available for the video.
  - licensedContent – Indicates whether the video contains content that has been claimed by a YouTube content partner.
- The status part contains two new properties. Video owners can set values for both properties when inserting or updating a video. These properties can also be retrieved with unauthenticated requests.
  - embeddable – Indicates whether the video can be embedded on another website.
  - license – Specifies the video's license. Valid values are creativeCommon and youtube .
The definition of the part parameter has been updated for the videos.list , videos.insert , and videos.update methods to list the newly added parts described above as well as the recordingDetails part, which had been inadvertently omitted.
The channel resource's new contentDetails.googlePlusUserId property specifies the Google+ profile ID associated with the channel. This value can be used to generate a link to the Google+ profile.
Each thumbnail image object now specifies the image's width and height. Thumbnail images are currently returned in activity , channel , playlist , playlistItem , search result , subscription , and video resources.
The playlistItems.list now supports the videoId parameter, which can be used in conjunction with the playlistId parameter to only retrieve the playlist item that represents the specified video.
The API returns a notFound error if the video that the parameter identifies cannot be found in the playlist.
The error documentation describes a new forbidden error, which indicates that a request is not properly authorized for the requested action.
The channel resource's snippet.channelId property has been removed. The resource's id property provides the same value.

An activity resource can now report a channelItem action, which occurs when YouTube adds a video to an automatically generated YouTube channel . (YouTube algorithmically identifies topics that have a significant presence on the YouTube website and automatically generates channels for those topics.)
The following search.list parameters have been updated:
- The q parameter is no longer designated as a filter, which means ....
- The relatedToVideo parameter has been renamed relatedToVideoId .
