I'm integrating Apple Pay with PayFort in a Swift iOS application, and I’m currently working on preparing a valid purchase request using Apple Pay, as described in PayFort’s documentation: 🔗 https://docsbeta.payfort.com/docs/api/build/index.html?shell#apple-pay-authorization-purchase-request
The documentation outlines the following required parameters:
apple_data
apple_signature
apple_header
apple_transactionId
apple_ephemeralPublicKey
apple_publicKeyHash
apple_paymentMethod
apple_displayName
apple_network
apple_type
Optional: apple_applicationData
I understand these should be derived from the PKPayment object after Apple Pay authorization, but I’m having trouble mapping everything correctly. Here’s what I’m seeing in code:
payment.token // Returns something like: <PKPaymentToken: 0x28080ae80; transactionIdentifier: "..."; paymentData: 3780 bytes>
payment.token.paymentData // Contains 3780 bytes of encrypted data
payment.token.paymentData.base64EncodedString()
// Returns a long base64 string, which at first glance seems like it could be used for apple_data,
// but PayFort doesn't accept it as-is — so this value appears to be incomplete or incorrectly formatted
I can successfully retrieve the following values from payment.token.paymentMethod:
apple_displayName
apple_network
apple_type
However, I’m still unsure how to extract or build the following in the format accepted by PayFort:
apple_data
apple_signature
apple_header
apple_transactionId
apple_ephemeralPublicKey
apple_publicKeyHash
apple_paymentMethod
These may be contained within the paymentData JSON, but I’m not sure how to decode it or if Apple allows decrypting it in a way that matches PayFort’s expected format.
How can I correctly extract or build apple_data, apple_signature, and apple_header from the Apple Pay token?
Also, how should I handle the decryption or decoding (if necessary) of paymentData to retrieve values like apple_transactionId, apple_ephemeralPublicKey, and apple_publicKeyHash?
If anyone has successfully set this up or has example code that bridges Apple Pay and PayFort’s expected request format, it would be super helpful!
Thanks in advance 🙏
