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

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

How dLocal handles VietQR

Payrails sends VietQR to dLocal as a QR payment for Vietnam, whatever the customer country code. dLocal uses the same QR method in other countries, so the Vietnam country code identifies the payment as VietQR.
The payment stays pending until dLocal reports the result.
