After being redirected to return_url from bank page, it is mandatory to do a Server-to-Server Order Status API call to determine the final payment status. Please ensure that you verify the order ID and amount transaction.
Sample return_url: https://merchant.shop.com/?status_id=21&status=CHARGED&order_id=guest-test-26&signature=wCFja5ZtDzm687LUxkqlw1NQYraC%2Bz540CitnlCouYI%3D&signature_algorithm=HMAC-SHA256

Once the payment status is determined via the API, the final status should be displayed to the user. This screen needs to be handled by the merchant, it is not provided by the SDK
