Invalid redirect_uri

An invalid redirect_uri error typically occurs when the redirect URI provided in an OAuth 2.0 authorization request is not registered with the authorization server.

The redirect URI is the endpoint to which the authorization server redirects the user after authentication and authorization. It must be a valid URL and must match the one registered with the authorization server during application registration.

To resolve this error, ensure that the redirect URI in your authorization request matches the one registered with the authorization server. Check the spelling and formatting of the URI, and make sure it is a valid URL. If you are using multiple redirect URIs, ensure that you are using the correct one for the specific authorization request.
