What happens when a payment in Radar for Fraud Teams matches both an allow and a block rule?

When a payment in Radar for Fraud Teams encounters both an allow and a block rule, the system prioritizes the allow rule. This means that if a payment satisfies the criteria of an allow rule, it will be processed and allowed to go through, even if there is a conflicting block rule present. The mechanism is designed this way to ensure that genuine transactions, which may be incorrectly flagged by block rules, can still be completed, thus minimizing the risk of false declines and ensuring a smoother checkout process for legitimate customers.

The setup of allow and block rules in the Radar system is meant to balance the need for security against fraudulent activities while also maintaining a positive user experience. In situations where conflicting rules exist, the system's bias towards allowing the transaction helps protect merchants from losing potential sales due to overly cautious fraud detection measures.
