Facing "Redirect URI mismatch" issue with integrating with Cisco Webex

I’m facing the redirect URI mismatch error when trying to integrate with Cisco webex. We’ve created an account in Cisco Webex Developer portal, configured the client credentials in Sales automation instance and updated Auth Profile as per the Pega Docs.

The URL when before entering cisco credentials ishttps://idbroker-eu.webex.com/idb/saml2/jsp/doSSO.jsp?client_id=C7d77ccff3243a4092925ec9fd913aa501062668716137ba2196f62a6a1676b3b&type=login&goto=https%3A%2F%2Fidbroker-eu.webex.com%2Fidb%2Foauth2%2Fv1%2Fauthorize%3Fredirect_uri%3Dhttps%3A%2F%2████████████████████%2Fprweb%2FPRRestService%2Foauth2%2Fv1%2Fredirect%26client_id%3DC7d77ccff3243a4092925ec9fd913aa501062668716137ba2196f62a6a1676b3b%26scope%3Dmeeting%3Arecordings_read%2520meeting%3Apreferences_write%2520meeting%3Aschedules_write%2520meeting%3Aschedules_read%2520meeting%3Arecordings_write%2520meeting%3Apreferences_read%26state%3Da3a12b2888c8cc69bffdf622458e174215c5e3b88343c36026f924297905da06%26response_type%3Dcode.

The URL when faced with below redirect URI mismatch error ishttps://idbroker-b-us.webex.com/idb/oauth2/oauth2Error.jsp?error=redirect_uri_mismatch&error_description=The%20redirection%20URI%20provided%20does%20not%20match%20a%20pre-registered%20value.

Need help on resolving this.
