China UnionPay International (UPI) is the only interbank network in Mainland China, East and Southeast Asia, and the biggest card scheme globally by number of cards.

This page explains how to accept UnionPay payments with SecurePlus authentication, the 3D Secure implementation used by China UnionPay. SecurePlus requires shoppers to identify themselves using a code sent to their phone number.

The integration steps for UnionPay without SecurePlus are exactly the same as for other cards.

Payment type Payment flow Countries Currencies Recurring Refunds Partial refunds Separate captures Partial captures Chargebacks
Credit card/Debit Card Direct International Multiple -white_check_mark- -white_check_mark- -white_check_mark- -white_check_mark- -white_check_mark-
See note 1
See note 2

1 Multiple partial captures are not supported.
2 If a payment has been authenticated with SecurePlus, you avoid the liability for chargebacks in case of fraud.

Before you begin

These instructions explain how to add UnionPay SecurePlus to your existing API-only integration. The API-only integration works the same way for all payment methods. If you haven't done this integration yet, refer to our API-only integration guide.

Before starting your integration:

  1. Make sure that you have set up your back end implementation.
  2. Add UnionPay in your test Customer Area.

If SecurePlus authentication is supported, you'll receive a resultCode of Pending.

/payments response

If the card does not support SecurePlus verification you'll receive the same response as for a regular credit card payment.

  2. Make a /payments/details request, specifying:

    • paymentData: The value from the /payments response.
