These are the playlists associated with your account. The id can be used in the query action to pull all videos for a given playlist, or to preload a playlist (tab) in a channel, i.e. ?playlist_id= to preload .
NOTE: Only manual playlists are supported in the query action at this point.
This is only available to logged in users. If you are a developer that doesn't have access to the account, please contact us.
