Note: You must have your online payment processing set to perform real-time authorizations in order to use AVS and CVV Rules to flag orders based on response codes as part of Risk Tools. Without real-time authorization, Risk Tools cannot check the address and card verification value provided by customers during checkout. View instructions for enabling real-time authorization of orders.
