Fraud Filter Reference

Unusual Order Filters

Filters Applied After Processing

Most filters are applied to the transaction request before forwarding the request to the

processor. The following filters are applied to the transaction results that the processor returns:

 AVS Failure filter (described on page 79)

 Card Security Code Failure filter (described on page 81)

 International AVS filter (described on page 90)

 Custom filters (described on page 91)

Transaction Data Required by Filters

“Downloading the Payflow SDK (Including APIs and API Documentation)” on page 51

provides the full list, for each filter, of each transaction value that you must send to Payflow.

For example, to ensure that the Total Item Ceiling filter can screen an order, you must provide

the total number of items that make up the order.

Unusual Order Filters

Unusual Order Filters identify transactions that exceed the normal size for your business.

Because fraudsters might not feel limited in their purchasing power, they sometimes place

orders that are much larger than the norm.

Total Purchase Price Ceiling Filter

What does the filter do?

This filter compares the total amount of the transaction (including tax, shipping and handling

fees) to the maximum purchase amount (the ceiling) that you specify.

The specified action is taken whenever a transaction amount exceeds the specified ceiling.

IMPORTANT:The Maximum amount per transaction setting in the Account menu controls

all transactions, even those that are less than or exceed the Total Purchase

Price Ceiling filter.

How does the filter protect me?

An unusually high purchase amount (compared to the average for your business) can indicate

potential fraudulent activity. Because fraudsters are not paying with their own money, they are

not price-sensitive.
