title: How to get code from Sign in with Apple in Unity when redirect urls localhost and 127.0.0.1 are not permitted
body: <p>I am trying to implement Sign in with Apple in the Unity editor. I am doing this using the REST API oauth flow. In my other oauth implementations I have been able to set a valid redirect url as localhost, so I can catch the response in the app with a http listener. However, Apple does not allow this address, not 127.0.0.1 . How can I get the response code back in Unity? Sign in with Apple is so new that I have not been able to find any answers so far. All of the guides are for implementing Sign in in a web client, not an app.</p>
