When creating risk rules and building your strategies for the Fraud Detection solution:
-
Check that your rule logic uses correct syntax.
-
Ensure
OR / ANDoperators and brackets are placed correctly to avoid unintended behavior. -
Ensure the properties used are available, because some properties are only available for post-auth rules. For example, ECI, AVS, and CVV fields.
-
Check the Troubleshoot strategies documentation.
-
Confirm that quote marks are correctly placed around strings.
