Hi.

We are developing the OAuth2 authentication (our App is in Development mode…) and after we redirect to the OAuth authorization URL we get the Invalid redirect … (4,700) error even when the OAuth Redirect URL is public and matches the one on the App settings page.

- App Client ID:  
LX4SostQ66Ur6hFAjoNKw

- Generated OAuth URL:  
[Sign In | Zoom](https://zoom.us/oauth/authorize?client_id=1UoAh8MzS5O05zF9qO3MXw&response_type=code&state=zoom ______ 1221397181,318b976f961142c85e3faa9501008894&redirect_uri=https://www.truthinit.com/xconnect/dev_zoom_oauth_redir)

- Error message:  
Invalid redirect: … (4,700)

- API Endpoint(s): Oauth/authorize

- How To Reproduce:  
Simply visit the provided OAuth URL above

Thanks in advance for your attention.
