AuthenticateCard Method

Determines only if a card has been lost or stolen.


public void AuthenticateCard();
Public Sub AuthenticateCard()


This method does not send an authorization, but instead it sends an authentication request. If successful the Code will be "85". If the card is stolen or otherwise not normal, the Code and Text will indicate such. You may send AVS (CustomerAddress and CustomerZip) as well as CVVData, and the AVSResult and CVVResult will be returned as normal.

.NET Standard Notes

To call this method in an asynchronous manner call AuthenticateCardAsync instead. When the method completes (or an error is encountered) the AuthenticateCardCompleted event will fire.
