This project demonstrates integrating the Hellō Identity Provider (IdP) in PHP using the HelloCoop PHP library.

• Authenticate users via the Hellō IdP.
• Simple integration with minimal configuration.
• Support for login and logout flows.

1. Create an Application on Hellō

   • Visit Hellō Console.
   • Create a new application and obtain the App ID.

2. Generate a Secret Key
   Run the following command in your terminal to generate a 32-byte hex key:

   openssl rand -hex 32

3. Set up Ngrok (Optional)
   If you want HTTPS redirects during local development, install and run Ngrok.

In the script:

1. Replace the placeholder HOST with your domain (use Ngrok if running locally):

   define('HOST', 'your-ngrok-domain.ngrok-free.app');

2. Replace APP_ID with your Hellō App ID:

   define('APP_ID', 'your-app-id-here');

3. Replace SECRET with your generated secret key:

   define('SECRET', 'your-secret-key-here');

1. Start PHP's Built-In Server
   Navigate to the example folder:

   php -S localhost:8080

2. Start Ngrok (Optional)
   In a separate terminal, start Ngrok for port 8080:

   ngrok http 8080

   Note down the generated HTTPS URL and update the HOST constant in the script.

3. Access the Demo
   Open the browser and navigate to your server's address (e.g., https://your-ngrok-domain.ngrok-free.app or your Ngrok domain).

• Login
  Click the Continue with Hellō button to initiate the login flow.
• Logout
  If logged in, the Logout button will be displayed. Use it to end the session.
• View Auth Data
  The authentication details are displayed in a pre block for debugging purposes.

• Ensure the application is running on HTTPS when deployed.
• Update your Hellō application's redirect URIs to include the appropriate endpoints (/api/hellocoop).

Enjoy using the Hellō Identity Provider for seamless user authentication!
