Create a PUBSUB app, beginner

API
2

Authentication is covered here

You should probably generate a user access token

There is a Node and PHP example at

That might be of use

TLDR:

  • Create a URL that goes to Twitch specifiying your client ID and the required scopes. (and other fields)
  • Get the streamers to click that link
  • They go to Twitch, they accept the connection between your Application and their account
  • They are redirected to your website with a code
  • Exchange the code for an access and refresh token

Then use that access token to connect to pubsub, and refresh the token when the access token dies/you get disconnected from PubSub.
