youtube ask for channel selection while authenticating

Question

I am using javascript sdk to authenticate google. In my webapp I am trying to upload video to youtube.

A youtube account might have multiple channels and I want to select the channel and send the information to the server with access token and all required value to upload a video.

I can authenticate a user from google but how can I display the youtube channel selection ui and also if there is no channel in the account I want to show error.

I have gone through youtube api but I found it very complex

Need help

YouTube is very different from other Google APIs. When your user authenticate your application they are not just authenticating you to YouTube you are actually getting authenticated to a single YouTube channel.

If you want to see the account selection you are going to have to force them to re authenticate you will then get a new access token associated to the channel that they pick.

prompt=consent should force them to re-authenticate but that depends on how you have implemented things.

Recap:

If a user has 5 channels you will to authenticate them once for each channel you will then have five access tokens each of which grants your application access to a single channel.
