Here is a video from Google Developers showing how to list all videos in a channel in v3 of the YouTube API. There are two steps: (1) Query Channels to get the "uploads" Id. e.g. https://www.googleapis.com/youtube/v3/channels?id={channel Id}&key={API key}&part=contentDetails (2) Use this "uploads" Id to query PlaylistItems to get the list of videos. e.g. https://www.googleapis.com/youtube/v3/playlistItems?playlistId={"uploads" Id}&key={API key}&part=snippet&maxResults=50
