YouTube Data API (v3) 支援透過 PubSubHubbub 傳送推播通知，PubSubHubbub 是適用於網路存取資源的伺服器對伺服器發布/訂閱通訊協定。系統會透過 HTTP Webhook 將通知推送至訂閱者，比起輪詢型解決方案更有效率。有了 PubSubHubbub 時，您的伺服器就能以近乎即時的方式找出事件，不必判斷最佳輪詢間隔，或重複擷取未變更的資料。
當頻道進行下列任何活動時，PubSubHubbub 回呼伺服器會收到 Atom 動態消息通知：
下列步驟說明如何訂閱通知：
-
設定可處理收到的 Atom 動態消息通知的回呼伺服器。
-
前往 Google 中心訂閱推播通知：
-
傳送至回呼伺服器的程序通知。通知的格式如下所示。請注意，您可以使用 <yt:videoId> 元素的值來識別新新增或更新的影片。您也可以使用 <yt:channelId> 元素的值來識別擁有該影片的頻道。

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 ```"]]
