Hi,
i'm trying to implement the Sign in with apple feature to our web login.
I configured the App ID and Service ID and added the return Url "https://example-app.com/redirect".
If i request the following authorize endpoint
https://appleid.apple.com/auth/authorize?response_mode=form_post&response_type=code&client_id=<clientId>&scope=name+email&state=<state>&redirect_uri=https://example-app.com/redirect
i constantly get the error message "invalid_request. Invalid redirect_uri."
Tried a lot of things. Using an uri under the registered domain, used this uri url encoded and not encoded, short uri, long uri, etc.
The uri i used in the link, ist the same i configured in the service ID configuration backend.
I have no idea whats wrong here. Maybe someone had the same problems and any solution for me.
Thanks a lot!
Daniel
