Need a step by step documentation for implementing of Apple pay in our website using javascript library and php as a backend.
I refer this https://developer.apple.com/documentation/apple_pay_on_the_web but didn't get any idea for this.
Apple Pay Integration on web
Start by setting up your environment by following the instructions in the Apple Pay Programming Guide https://developer.apple.com/documentation/apple_pay_on_the_web/configuring_your_environment.
You'll need to create a merchant ID and a payment processing certificate in the Apple Developer portal. Follow the instructions in the guide (https://developer.apple.com/help/account/configure-app-capabilities/configure-apple-pay-on-the-web ) to create these.
Once you've set up your environment, you can begin implementing the Payment Request API in your website's JavaScript code. You can find detailed instructions on how to do this in the Apple Pay Programming Guide (https://developer.apple.com/documentation/apple_pay_on_the_web/payment_request_api/setting_up_the_payment_request_api_to_accept_apple_pay ).
After the payment request is initiated by the user, the Payment Request API will return a payment token. The payment token should be sent to your server-side code (PHP) for processing.
On the server side, you can use the payment token to create a payment request and send it to the payment gateway. The payment gateway will handle the transaction and return a response to your server-side code.
Once the payment has been processed, you can use the response from the payment gateway to update your website's JavaScript code and inform the user of the payment's status.
By following these steps you'll be able to implement Apple Pay on your website using the Payment Request API and a PHP backend.
Hope this helps.
