YouTube Channel ID Finder

Paste a channel @handle, channel URL, or custom name and get its canonical UC… channel ID — plus the WebSub topic feed URL you'd subscribe to. Free, no signup.

Why you need the UC… id

YouTube's feeds and push notifications are keyed by the UC… channel id, not the @handle. The reliable way to get it is the channel page's <link rel="canonical"> — a naive grep of the HTML often picks up an embedded channel instead. This tool does that resolution for you and caches it.

From channel ID to a webhook

Once you have the id, you can poll the feed yourself — or skip all the plumbing and let Feedhook POST your app the moment a new video publishes. See how YouTube push works in the WebSub guide, the recipes (Discord, Slack, no-code), or just run it:
