Our payment gateway has approved Website B for payment collection. We also have Website A, where customers place orders. During checkout, we redirect the customer from Website A to Website B to complete the payment. Once the payment is successful on Website B, it sends a confirmation/response back to Website A, and the order status is updated accordingly on Website A. Important: The payment gateway should only see and process transactions on Website B. It should not receive or track any direct request or integration reference from Website A when the customer is redirected for payment.
