You don't use python code?
If you do it's basically a copy-paste (except you gotta else delete the logger lines or replace them with prints), if you don't (as in you're using something harder to understand) then I would be amazed you don't understand the code, since it's basically, a post to the submit_url with video_id (you know, this: 7557058101258620191), then you get the response with some kind of task_id and you get the url to the actual video through appending that to the result_url (actually it might be another response which would give you the direct url to video in "play_url", I didn't check).
Pretty much everything else is optional, headers probably too though I guess it's not a bad thing to use them.
