Setup steps

Please visit our GitHub for setup instructions.

How does it work?

● Your app navigates users to Apple Authorization Endpoint in a web browser

● Users perform sign-in using their login and password

● Apple Authorization Endpoint redirects users to Return URL (which is Authorization Middleware, or may be your website as well) and provides an authorization code (which can be later exchanged for access_token), id_token (if requested) and user info like first_name, last_name and email (if requested and only once at first sign-in)

● Authorization Middleware transmits the authorization code and user info to your app (using deep linking when possible, or with a web request made by the app when not)

● The app exchanges the code for access_token (and may receive id_token as well) by creating JWT signed with p8 private key (ES256)
