Here's an update. I called support and got a brand-new Api Username, Client ID, and Client Secret. Using the new info, I was able to get an authorization code as before. Using that, I posted the following using Postman.
Code: Select all
Note that I left the 33%3A prefix on the auth_code. I've double-checked all the values. I still get the same error:
"error_description": "Invalid, expired, or revoked authorization code."
Can anyone help?
