Get all of the videos (the uploaded playlist) for a given channel on YouTube (or a list of channels). This will get the upload playlist for each channel and then get all the videos for all of the upload playlists.
Import this formula to add the 2 chained workflows into your account. Start by executing the (1/2) workflow and provide the Channel ID(s) you want to get all the videos for. Then enter your YouTube API key and you’ll get results back. Please be aware of your YouTube Data API usage, as this may result in charges from the Google API.
