• When the user authorizes the payment using Face ID or Touch ID on their iOS device, the didAuthorizePayment event will be dispatched. In this step, you must pass the token to ApplePayService found within the PKPayment object. Here is an example:

  func paymentAuthorizationController(_ controller: PKPaymentAuthorizationController, didAuthorizePayment payment: PKPayment, handler completion: @escaping (PKPaymentAuthorizationResult) -> Void) {
        Task {
            do {
                let apiPaymentResult = try await applePayService!.authorizePayment(request: paymentRequest, token: payment.token)
                handleCompletedPaymentResult(apiPaymentResult, handler: completion)
            }  catch {
                // Handle the error case
                print(error)
                completion(PKPaymentAuthorizationResult(status: .failure, errors: [error]))
            }
        }
    }

    func handleCompletedPaymentResult(_ apiPaymentResult: ApiPayment, handler completion: @escaping (PKPaymentAuthorizationResult) -> Void) {
        print("Got payment, status: \(apiPaymentResult.status)")
        print(apiPaymentResult.status)
        print(apiPaymentResult.id)
        switch (apiPaymentResult.status) {
        case .paid:
            completion(PKPaymentAuthorizationResult(status: .success, errors: []))
        case .failed:
            let message: String = if case let .applePay(source) = apiPaymentResult.source {
                source.message ?? "unspecified"
            } else {
                "Returned API source is not Apple Pay"
            }
            completion(PKPaymentAuthorizationResult(status: .failure, errors: [DemoError.paymentError(message)]))
        default:
            completion(PKPaymentAuthorizationResult(status: .failure, errors: [DemoError.paymentError("Unexpected status returned by API")]))
        }
    }

info

• Don't forget:
  • Call the completion. If, for some reason, the closure is not called, it would result in the Apple Pay sheet hanging or other unexpected behavior. Therefore, it's crucial to ensure that the completion is always called, regardless of the payment process outcome.
  • Import PassKit.

---

• An error will be printed if the API key format is incorrect.

• After the payment is finished, the paymentAuthorizationControllerDidFinish delegate function will be called; allowing you to dismiss the controller within it.
