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. CS
var request = new TransactionRequest {
    Amount = 10.00M,
    PaymentMethodNonce = nonceFromTheClient,
    DeviceData = deviceDataFromTheClient,
    Options = new TransactionOptionsRequest {
        SubmitForSettlement = true
    }
};
Result<transaction> result = gateway.Transaction.Sale(request);
if (result.IsSuccess()) {
    // See result.Target 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.
