YouTube Data API (v3) 支持通过 PubSubHubbub 推送通知，PubSubHubbub 是一种服务器到服务器发布/订阅协议，适用于网络可访问的资源。通知通过 HTTP 网络钩子推送给订阅者，比基于轮询的解决方案更高效。借助 PubSubHubbub，您的服务器可以近乎实时地了解事件，而无需确定最佳轮询间隔，也无需重复提取未更改的数据。
当某个频道执行以下任意活动时，您的 PubSubHubbub 回调服务器会收到 Atom Feed 通知：
以下步骤说明了如何订阅通知：
-
设置可以处理传入的 Atom Feed 通知的回调服务器。
-
使用 Google Hub 订阅以接收推送通知：
-
处理向您的回调服务器发送的通知。通知格式如下所示。请注意，您可以使用 <yt:videoId> 元素的值来识别新添加或更新的视频。您还可以使用 <yt:channelId> 元素的值标识拥有该视频的频道。

Notifications, sent as Atom feeds, include the video and channel IDs, as well as video titles and other information.\n"],null,["# Subscribe to Push Notifications\n\nThe YouTube Data API (v3) supports push notifications via [PubSubHubbub](https://github.com/pubsubhubbub/), a server-to-server publish/subscribe protocol for Web-accessible resources. Notifications are pushed out to subscribers via HTTP webhooks, which is much more efficient than polling-based solutions. With PubSubHubbub, your server finds out about events in near real-time, without having to determine the optimal polling interval or repeatedly fetching data that hasn't changed.\n\nYour PubSubHubbub callback server receives Atom feed notifications when a channel does any of the following activities:\n\n\u003cbr /\u003e\n\n- uploads a video\n- updates a video's title\n- updates a video's description\n\n\u003cbr /\u003e\n\nThe following steps explain how to subscribe to notifications:\n\n1. Set up a callback server that can handle incoming Atom feed notifications.\n\n2. Use the [Google](https://pubsubhubbub.appspot.com/subscribe) hub to subscribe to receive push notifications:\n\n - Set the **mode** to `subscribe`. (Or set the mode to `unsubscribe` to cancel a subscription.)\n\n - Set the **callback URL** to the URL that you set up in step 1.\n\n - Set the **topic URL** to `https://www.youtube.com/feeds/videos.xml?channel_id=`**CHANNEL_ID**, where **CHANNEL_ID** is the [YouTube channel ID](/youtube/v3/docs/channels#id) for which you want to retrieve push notifications.\n\n3. Process notifications sent to your callback server. The notification format is shown below. Note that you can use the `\u003cyt:videoId\u003e` element's value to identify the newly added or updated video. You can also use the `\u003cyt:channelId\u003e` element's value to identify the channel that owns that video.\n\n ```\n \u003cfeed xmlns:yt=\"http://www.youtube.com/xml/schemas/2015\"\n xmlns=\"http://www.w3.org/2005/Atom\"\u003e\n \u003clink rel=\"hub\" href=\"https://pubsubhubbub.appspot.com\"/\u003e\n \u003clink rel=\"self\" href=\"https://www.youtube.com/xml/feeds/videos.xml?channel_id=CHANNEL_ID\"/\u003e\n \u003ctitle\u003eYouTube video feed\u003c/title\u003e\n \u003cupdated\u003e2015-04-01T19:05:24.552394234+00:00\u003c/updated\u003e\n \u003centry\u003e\n \u003cid\u003eyt:video:VIDEO_ID\u003c/id\u003e\n \u003cyt:videoId\u003eVIDEO_ID\u003c/yt:videoId\u003e\n \u003cyt:channelId\u003eCHANNEL_ID\u003c/yt:channelId\u003e\n \u003ctitle\u003eVideo title\u003c/title\u003e\n \u003clink rel=\"alternate\" href=\"http://www.youtube.com/watch?v=VIDEO_ID\"/\u003e\n \u003cauthor\u003e\n \u003cname\u003eChannel title\u003c/name\u003e\n \u003curi\u003ehttp://www.youtube.com/channel/CHANNEL_ID\u003c/uri\u003e\n \u003c/author\u003e\n \u003cpublished\u003e2015-03-06T21:40:57+00:00\u003c/published\u003e\n \u003cupdated\u003e2015-03-09T19:05:24.552394234+00:00\u003c/updated\u003e\n \u003c/entry\u003e\n \u003c/feed\u003e\n ```"]]
