Play all videos of a playlist from yoututbe data api

I can get video id from PlaylistItems and play them using youtube player. But is there any way I can get the entire playlist to be played (one video after another like on youtube). On youtube for any playlist we have url like

https://www.youtube.com/watch?v=zqpkt80WbX0&list=RDaPevLsjcJ7c&index=6

How do we get the 'list' for any video?
