AVSOnly Method

Used to check the validity of the card without authorizing funds.

Syntax

int AVSOnly();

Remarks

This method can be used if you wish to perform fraud (AVS and CVV) checks on a card, but don't actually wish to charge the customer. This is useful for pre-ordering an item that has not yet been released or is currently back- ordered. The card information is validated by the merchant, and when the item is later in stock and ships to the customer, an Sale transaction can be performed.

Note: If the Gateway does not support this method, the class will fails with an error.

Error Handling

This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message. (Note: This method's result code can also be obtained by calling the GetLastErrorCode() method after it returns.)
