Lists

Fraud Lists offer a clearer overview and facilitate the handling of criteria used for fraud protection. Rather than creating numerous Fraud Rules for specific types of values, you can simply establish a single Fraud Rule that applies to the values from a Fraud List.

The default view of the Fraud Lists consists of Lists created by Shift4. They cannot be deleted. System Lists can be extended by adding values from a charge view or customer view

Merchants can also create their own Fraud Lists.

Please note that in case of system Fraud Lists, items added to the Approve List cannot be included in the Decline List. For example, you cannot pre-approve and ban an email address at the same time.

Please note that Fraud Lists and Fraud Rules are not retroactive, meaning they only apply to charges created after the introduction of the rule or the addition of an item to the list. Charges that have been declined or approved based on the fraud rule will retain their status, even if the rule is later edited or deleted.

How to Add a Custom Fraud List

1. Navigate to the Fraud on the left side panel, then select Lists.

4. Confirm by clicking Add. A new List should now be visible on the main view.

5. To populate the List, simply click on it and then use the Add Value button.

When you add an item to the List, you can expand it with a new value and review the existing values and associated Fraud Rules. Additionally, you can easily edit the List’s name by using the context menu next to the Add Value button.

How to Delete a Custom Fraud List

How to Add a Value to a Fraud List From the Charge View

2. Click on the selected charge.

3. Click the Add To List button in the upper right corner.

4. Choose a field to which a Fraud Rule should be applied, and specify the type of Rule (Approve or Decline). There are no limitations on the number of fields you can pre-approve or ban in the same action.

5. Once you confirm the changes by clicking Save at the bottom of the modal, new items will appear on respective default Fraud Lists. You can select a field from the metadata; if there is no custom List available for this field, one will be automatically created and populated.
