When I go to obtain a token for a user at this endpiont: https://developer.squareup.com/reference/square/oauth-api/obtain-token, It just sends an error response “Not Found”.
I have double/triple checked that the client_id and client_secret (Application ID, Application Secret) are correct. The grant_type is “authorization_code” and the code is the code that is sent in the url after authorization. The user authorizes and all of the data is correct, but I constantly get “Not Found”.
This was working for me previously, but has stopped working all of a sudden. How do I fix this?
