Apple Sign-In (SSO) allows you to use Apple's secure authentication service for user login and data retrieval. Setting up Apple SSO involves creating the required OAuth credentials and configuring your environment variables.

Required Environment Variables

Before you begin, ensure you have the following environment variables set up in your .env file:

• APPLE_CLIENT_ID: Your Apple OAuth client ID
• APPLE_CLIENT_SECRET: Your Apple OAuth client secret

Acquiring Apple OAuth Client ID and Client Secret

1. Create an Apple Developer Account: If you don't have an Apple Developer account, you will need to register.

2. Create an App ID:

   • Go to Apple Developer Portal.
   • Under Certificates, Identifiers & Profiles, select Identifiers.
   • Click the "+" button to create a new App ID.
   • Register your App ID and ensure it has the appropriate capabilities for Sign-In with Apple.

3. Configure Sign-In with Apple:

   • After creating the App ID, configure it to use Sign-In with Apple.
   • Navigate to the Keys section in the Apple Developer Portal.
   • Click the "+" button to create a new key.
   • Select the Sign In with Apple capability.
   • Download the key after generating it and keep it secure.

4. Create a Service ID:

   • Go to Certificates, Identifiers & Profiles > Identifiers > Service IDs.
   • Click the "+" button to create a new Service ID.
   • Enable Sign-In with Apple for this Service ID.

5. Configure Redirect URI:

   • Under the Sign-In with Apple configuration for your Service ID, add a redirect URI that matches the one used in your OAuth flow.

6. Generate Apple Client Secret:

   • The APPLE_CLIENT_SECRET is a JWT generated using your Apple private key and other details.

   • Use libraries such as PyJWT to generate this JWT.

     import jwt
     import time
     from uuid import uuid4
     
     PRIVATE_KEY = "-----BEGIN PRIVATE KEY-----\n...your private key...\n-----END PRIVATE KEY-----\n"
     
     def generate_client_secret():
       headers = {
           "kid": "YOUR_KEY_ID",
           "alg": "ES256",
       }
       claims = {
           "iss": "YOUR_TEAM_ID",
           "iat": int(time.time()),
           "exp": int(time.time()) + 86400*180,
           "aud": "https://appleid.apple.com",
           "sub": "YOUR_SERVICE_ID",
       }
       client_secret = jwt.encode(claims, PRIVATE_KEY, headers=headers, algorithm="ES256")
       return client_secret
     
     APPLE_CLIENT_SECRET = generate_client_secret()
     

Setting Up the Environment Variables

Once you have the APPLE_CLIENT_ID and APPLE_CLIENT_SECRET, add them to your .env file:

APPLE_CLIENT_ID=your_apple_client_id
APPLE_CLIENT_SECRET=your_apple_client_secret

Required Scopes for Apple SSO

The required scopes for Apple SSO include:

• name: To get the user's name.
• email: To get the user's email address.

Additional Notes

• This implementation uses placeholder values for first_name, last_name, and email which should be replaced with actual logic to capture user information during the initial token exchange.
• The send_email function is not implemented because Apple OAuth does not support sending emails directly via API.
• Ensure all sensitive information such as private keys and client secrets are securely stored and managed.
