Trust Payments (Secure Trading)

CVV codes

The CVV codes are send in on the first Credit Card add request and as it is not stored by iPayment the gateway. The CVV code will only be validated once when adding the card. It is not legal to store the CVV code so any additional request will not have the CVV code checked.
