I need to edit parameters for end screen while upload a video, but I don\'t see anything in the document of the API.
It is possible edit end screen through the API?<
I did a little bit of research and found something, YouTube allows to send the endscreen template but with a special parameter like "onBehalfOfUser" or sort of and with a special format, but they are validating because there is a NOTE: this is only for youtube partners. So we can assume that tubebuddy it is a youtube partner and it is allowed to use this, probably they sent new endpoints too.
Unfortunately for us, common users, it's not possible and probably won't be ever.
This is not yet supported as of this moment. You're trying to turn Youtube Data API into a video editor which is currently out of its scope.
