How to send Apple Pay Token to PayU - swift

Question

I haver an application which should use Apple Pay.
As soon as user accept payment and Apple Pay works well, like Face ID or PIN,
I would like to send Apple Pay Token to PayU.
Unfortunatelly I did not find and support in PayU (https://czech.payu.com/en/)
In my ApplePayViewController I have method like:
class ApplePayViewController: {
func submitToken(payment: PKPayment, completion: #escaping (PKPaymentAuthorizationResult) -> Void) {
let result = PKPaymentAuthorizationResult(status: .failure, errors: nil)
let jsonPayment = try? JSONSerialization.jsonObject(with: payment.token.paymentData, options: []) as? Dictionary<String, AnyObject>
if let jsonData = jsonPayment {
let jsonTokenString = String(decoding: payment.token.paymentData, as: UTF8.self)
print("Json Data String: \(jsonTokenString)")
}
// What should be sent to PayU?
// paymentData? https://developer.apple.com/documentation/passkit/pkpaymenttoken/1617000-paymentdata
// Or data from Payment Token Structure https://developer.apple.com/documentation/passkit/apple_pay/payment_token_format_reference#//apple_ref/doc/uid/TP40014929
// Data are sent to my server over API like
// https://<URL>/api/send_payment&user=<username>&token=<token>&payment_data=<ApplePayToken>
do {
send_payment(data: paymentData, completion: { apiResponse in
switch apiResponse {
case .success(let zapisStatus):
result.status = PKPaymentAuthorizationStatus.success
completion(result)
case .failure(let error):
result.status = PKPaymentAuthorizationStatus.failure
completion(result)
}
})
}
}
extension ApplePayViewController: PKPaymentAuthorizationViewControllerDelegate {
func paymentAuthorizationViewController(_ controller: PKPaymentAuthorizationViewController!, didAuthorizePayment payment: PKPayment!, handler completion: #escaping (PKPaymentAuthorizationResult) -> Void) {
let status = PKPaymentAuthorizationStatus(rawValue: 0)!
switch status.rawValue {
case 0:
self.paymentStatus = PKPaymentAuthorizationStatus.success
completion(PKPaymentAuthorizationResult(status: PKPaymentAuthorizationStatus.success, errors: nil))
case 1:
self.paymentStatus = PKPaymentAuthorizationStatus.failure
completion(PKPaymentAuthorizationResult(status: PKPaymentAuthorizationStatus.failure, errors: nil))
default:
self.paymentStatus = PKPaymentAuthorizationStatus.failure
completion(PKPaymentAuthorizationResult(status: PKPaymentAuthorizationStatus.failure, errors: nil))
}
if payment.token.paymentData.count > 0 {
self.submitToken(payment: payment)
}
}
The data are send over by this code:
public func getURLRequest(endpoint: String, data: Data) -> URLRequest{
guard let url = URL(string: RestAPIHelper.RestAPIKeys.url_pub + endpoint) else {
fatalError()
}
var urlRequest = URLRequest(url: url)
urlRequest.httpMethod = "POST"
urlRequest.addValue("application/x-www-form-urlencoded", forHTTPHeaderField: "Content-Type")
urlRequest.httpBody = data
return urlRequest
}
func send_payment(data: Data, completion: #escaping(Result<[UserPlatbyInfo], APIError>) -> Void) {
let urlRequest = getURLRequest(endpoint: APIInterface.user_zapisplatbu.rawValue, data: data)
let dataTask = URLSession.shared.dataTask(with: urlRequest) { respData, resp, _ in
// Handle return status
dataTask.resume()
}
Basically I don't know what PayU expects in order to accept ApplePayToken.
