AVSOnly Method

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

Syntax

icharge.AVSOnly([callback])

Callback

The 'callback' parameter specifies a function which will be called when the operation completes (or an error is encountered). If the 'callback' parameter is not specified, then the method will block and will not return until the operation completes (or an error is encountered).

The callback for this method is defined as:

function(err){ }

'err' is the error that occurred. If there was no error, then 'err' is 'null'.

'err' has 2 properties which hold detailed information:

err.code
err.message

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.
