99% of the time you only ever need to use
If a endpoint requires a scope, then it needs auth.
If it lists no scopes then it doesn’t
Some end points (users) will accept a userID, or tell you the user for the Auth you specified. (So the userID is optional and the error code tells you what to do)
Interrupt for Users eaxmple
A call to https://api.twitch.tv/helix/users
- with only a ClientID will error
- with a user oAuth will give you the user that the oAuth belongs to
- with a clientID and a id (or login) will give you the user you asked for
- with a user oAuth and a id (or login) will give you the user you asked for
- with only a server oAuth with error
- with a server oAuth and a id (or login) will give you the user you asked for
Onwards
BUT, all end points that DON’T require an oAuth, you can still specify either a user oAuth (with scopes) or a Client Credentials oAuth to benefit from higher Rate Limits
TLDR: make a request to an end point, read the error message if you get one. (if the docs for that endpoint are unclear)
