Updates an existing playlist
This call requires the id of the playlist you want to update as a path parameter. The body should contain new values for the properties you want to update. For example, you may want to add assets to a static playlist, or rename the playlist itself. When you update a playlist, be sure to include any contents of the playlist you want to keep; otherwise, they will be removed.
To learn more about a playlist’s properties, please see Get all playlists.
A 204 code is returned when a playlist is successfully updated.
