Web Service

Sign in with Apple REST API

Communicate between your app servers and Apple’s authentication servers.

Overview

The Sign in with Apple REST API is a web service that connects you to Apple's authentication servers. Use this service to generate and validate the identity tokens used to verify a user’s identity.

To sign in from a web app or other platform, like Android, use Sign in with Apple JS. Alternatively, to let users set up accounts and sign in to your native iOS, macOS, tvOS, and watchOS apps, use the AuthenticationServices framework.
