Accept WeChat Pay payments from customers in China with Nuvei as the payment service provider (PSP). The customer selects WeChat Pay, scans a QR code on the Nuvei page with the WeChat app and returns to your site.

Request fields for Nuvei

Send these fields in the authorize request, in addition to the standard authorize fields. Payrails checks Required fields and returns an error when one is missing. Fields required by the PSP pass the Payrails checks but the PSP can decline the payment without them.

    }
  },
  "returnInfo": {
    "success": "https://example.com/success",

How Nuvei handles WeChat Pay

Payrails sends WeChat Pay to Nuvei only for customers in China. A missing meta.customer.country.code returns an error, and any value other than CN returns an error.
Payrails sends WeChat Pay payments to Nuvei as a sale, so Nuvei captures the payment when the customer confirms it.
Nuvei has no test environment for WeChat Pay. Test with low-value payments in live mode.
