add new payment - CS-Cart

website in Egypt using CS-Cart and want to add new payment via VISA or Mastercard through a Bank from Egypt. (i have php files from the bank and MIGS url + the test form is valid) - add the newpayment and test it online. - we will inform the bank that the test is working fine and they will try the test. - then add the real functions instead of the test. - test the payment with a real transaction (small amount)
