YouTube Api v3 - topic channel videos

Question

So how do I get posted videos from a channel that is "auto-generated by YouTube" (topic)? https://www.youtube.com/channel/UCSkJDgBGvNOEXSQl4YNjDtQ/videos

I can get topic ids from channel call but when I search by this topic ids I get a completely different results.

And if I run search api call with:

{
  'part':'snippet',
  'channelId':'UCSkJDgBGvNOEXSQl4YNjDtQ',
  'topicId':'/m/03lty'
} 

I get only playlists and channels. No video results.

Answer 1

You have to do this way:

• get the channel id in your case 'UCSkJDgBGvNOEXSQl4YNjDtQ'

• call playlists endpoint and retrieve the id

  GET https://www.googleapis.com/youtube/v3/playlists?part=id&channelId=UCSkJDgBGvNOEXSQl4YNjDtQ&maxResults=1&key={YOUR_API_KEY}

• call playlistitems using the retrieved id

  GET https://www.googleapis.com/youtube/v3/playlistItems?part=snippet&playlistId={RETRIEVED_ID_COMES_HERE}&key={YOUR_API_KEY}

This works like a charm to me.

Answer 2

Videos featured in an auto-generated channel are not created (uploaded) by this channel, so they don't show up in search results restricted to this channel id.

You can however get a list of videos associated with the topic by removing the channelId parameter.

EDIT: You can also do subsequent calls to retrieve videos for each playlist published by the auto-generated channel, with calls like this: https://developers.google.com/apis-explorer/#p/youtube/v3/youtube.playlistItems.list?part=snippet&playlistId=PLfY-m4YMsF-OSodOIoTKPVblnYvdjU2Tn&_h=7&
