Unable To Get Twitch API OAuth For PHP

I am looking at https://dev.twitch.tv/docs/authentication/getting-tokens-oauth/#oauth-client-credentials-flow and Barry’s GIT ‘Notes’. Both are saying to use the URL https://id.twitch.tv/oauth2/token to get an access token. When I try this in my code and browser I get an error 404 page not found.

I did use the “Provide Feedback For This Page” link in an attempt to report this. Without this access token I don’t think I can get started. Am I right? Did the Twitch API developers break something in the removal of their API V5?

Overall what you are saying is starting to make sense to me.
