UnionPay

Server-side Implementation

Availability
This integration for UnionPay has been deprecated, as UnionPay can now be processed as a credit card through their partnership with Discover. See our credit card guide for more information.

Creating transactionsAnchorIcon

You will receive a payment method nonce when your client successfully tokenizes your customer's payment information. Pass this nonce to your server and create a transaction. Collect device data from the client and include the deviceDataFromTheClient in the transaction.
  1. PHP
$result = $gateway->transaction()->sale([
  'amount' => '10.00',
  'paymentMethodNonce' => $nonceFromTheClient,
  'deviceData' => $deviceDataFromTheClient,
  'options' => [
    'submitForSettlement' => True
  ]
]);

if ($result->success) {
  // See $result->transaction for details
} else {
  // Handle errors
}

Delayed settlementAnchorIcon

If the UnionPay card is not a debit card, you can choose to submit the transaction for settlement separately. This can be helpful if you have a delayed order fulfillment process and prefer to wait to settle the transaction until you're ready to provide your goods or services. For details on this transaction flow, see the Transaction: Submit For Settlement reference.
