how do i integrate apple pay

To integrate Apple Pay, you can follow the updates and guidelines provided in the session titled What’s new in Wallet and Apple Pay from WWDC 2024. Here are the key steps:

1. Import the Apple Pay JavaScript SDK:

   • Ensure you import the Apple Pay JavaScript SDK version 2.0 or higher. It's recommended to place this in the head tag of your HTML document to ensure that Apple Pay is ready as soon as your page loads.

2. Use the Apple Pay Button from the JavaScript SDK:

   • Use the JavaScript SDK Apple Pay button instead of the CSS implemented variant. This ensures that non-Safari browser support works.

3. Check Payment Availability:

   • Use the canMakePayments API or the new Apple Pay capabilities API to determine when and where to display the Apple Pay button. The canMakePayments API is being deprecated in favor of the new Apple Pay capabilities API, which provides a cleaner, universal solution.

4. Handle Non-Safari Browsers:

   • For non-Safari browsers, a scannable code will pop up on the screen. Users can scan this code with their iPhone to complete the payment securely and privately. This uses the same payment systems as a typical iPhone Apple Pay transaction.

5. Testing and Best Practices:

   • Refer to the developer documentation for beta testing your integration.
   • Ensure that the Apple Pay button is always shown if canMakePayments returns true.
   • Follow the acceptable use guidelines for Apple Pay on the web or the Human Interface guidelines for more details on when and where to show the Apple Pay button.
