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

After the customer confirms the payment in WeChat, Nuvei returns them to your success or error URL. Confirm the result through webhook notifications or the execution status before you fulfill the order.

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.
