How can I get a channel ID from YouTube?

Solution 1:

To obtain the channel id you can view the source code of the channel page and find either data-channel-external-id="UCjXfkj5iapKHJrhYfAF9ZGg" or "externalId":"UCjXfkj5iapKHJrhYfAF9ZGg".

UCjXfkj5iapKHJrhYfAF9ZGg will be the channel ID you are looking for.

Solution 2:

An easy answer is, your YouTube Channel ID is UC + {YOUR_ACCOUNT_ID}. To be sure of your YouTube Channel ID or your YouTube account ID, access the advanced settings at your settings page

And if you want to know the YouTube Channel ID for any channel, you could use the solution @mjlescano gave.

https://www.googleapis.com/youtube/v3/channels?key={YOUR_API_KEY}&forUsername={USER_NAME}&part=id
