Using the tutorial on https://webkit.org/blog/8182/introducing-the-payment-request-api-for-apple-pay/

I successfully implemented apple pay on a website.

Now I am trying to get the first 6 digits of the customers credit card number for calculating OPC fees.

So I debugged and did some logging on the response object at code level (referrring to the tutorial above):

const response = await request.show();

  var jStr = JSON.stringify({
    methodName: response.methodName,
    details: response.details,
  }, undefined, 2);

  console.log(jStr);

When debugging, I got infos like customer name, card brand , card type and the last 4 digits of the card number.

Is there any way to get the first 6 digits of the credit card number ?

Is there any apple pay endpoint for this purpose (server to server communication), similar like when getting the payment session (https://developer.apple.com/documentation/apple_pay_on_the_web/apple_pay_js_api/requesting_an_apple_pay_payment_session) ?

I already contacted the apple support via phone, but they could not help me (they had no technical knowledge).

Thanks and kind regards

Getting the first 6 digits of the card is not something that is currently supported. As mentioned, only the last 4 digits are available. Calculating the OPC information/fees would currently be an enhancement request as there is not an API for this.

Thank you for the response.

I just decrypted the payment data from inside the PaymentToken using this method: https://developer.apple.com/library/archive/documentation/PassKit/Reference/PaymentTokenJSON/PaymentTokenJSON.html

Now I have all the information like device-specific account number (applicationPrimaryAccountNumber) and card expiration date in plaintext.

Can I use any of the infromation inside the PaymentToken to find the issuing bank of this card ?

Referring to the apple link above:

7.Use the decrypted payment data to process the payment.

I have made it up to step 7, now how exctly can I process the payment ? What is the next step. I am missing a manual or some sort of detailed instruction, could not find any on the apple pay docs.

By the way: I don't use any third party payment processor.

Thank you and best regards

I would recommend engaging with a payment processor for instructions on how to actually process the payment and for further information on the card type.

To see a list of payment service providers to integrate with, check out the payment platforms page for your specific country here.

Select the Payment Service Providers tab.
