Describe the problem/error/question
I’m trying to set up credentials using the generic OAuth2 API type. When I try to authorize the app, I go through the login process and approval but when the callback page is loaded, it shows a 401 error saying:
“The provided client id and secret do not match an existing application”
What is the error message (if any)?
“The provided client id and secret do not match an existing application”
Please share your workflow
- I added OAuth2 API credentials.
- I entered all the relevant fields (auth urls, client id, client secret, etc.)
- Tried to authorize
- Authorized the app
- Callback page loads
- 401 error is displayed
