Webex Teams - Using an integration vs. my own credentials


New to make.com. I have built a couple workflows using my own Webex oauth credential, but I’m trying to use an integration service via webex. Has anyone had any success for this?

The error I am getting when I run the authorization via webex is: Resource not Found.

URL: Sign In - Webex

What Webex comes back with is this URL, indicating that the redirect_uri is not setup correctly:
OAuth2 Authorization - Webex.

In the Webex app, here are the redirect URIs being used. Is there maybe one or two that I am missing?

Just wondering if anyone has had any experience with this sort of integration?
