@RitchiS99 can you provide a reference the the relevant OAuth 2 RFC document that specifies a authorize_json endpoint?

We should not be adding non-standard extensions to this library; you can always extend the class yourself if you need a non-standard feature.

Hi, my commit is because alexa is needing such an endpoint. I am not sure if there is an "offical" endpoint for this, but i would highly recommend adding this, because a communication with alexa shall be possible

Closing this because it doesn't appear to be documented as part of the OAuth 2 RFCs/OIDC docs.

Also none of the PR checklist items were provided.

If you want to flesh this out some more to answer the questions around documentation, etc. please reopen it.
