The system supports preliminary verification of incoming transactions based on black and white lists of customer data.
Black lists include data of customers whose payments merchants prefer not to accept — for example, due to suspected fraud. Any payment containing values that match entries in the black list is automatically rejected before being sent to the acquirer for further verification and processing. However, the black list does not block refunds.
White lists contain data of trusted customers. When processing payments, if a transaction parameter matches a value in the white list, the system skips Action Type rule checks for that transaction.
You can add the following data to the black and white lists:
• Card number mask used for payment
• Customer’s email address
• Customer’s IP address
To manage these lists, use the buttons described in the table below.
