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

In the context of Stripe's Radar for Fraud Teams, the system evaluates rules for fraud detection to ensure transactions are processed securely. When a payment meets the criteria for both an allow rule and a block rule, the allow rule takes precedence. This means that despite the block rule indicating potential fraud, if the transaction also matches an allow rule, it will be permitted to proceed.

This prioritization of allow rules over block rules is designed to help ensure legitimate transactions are not incorrectly declined. Allow rules typically focus on characteristics that indicate a transaction is likely to be safe based on historical data and risk assessments. Consequently, even if there are concerns raised by block rules, the safety of the transaction as indicated by allow rules will lead to its approval.

In this scenario, options that suggest the payment will be flagged for review, blocked, or require manual approval do not accurately represent the hierarchy in rule enforcement established by Stripe's framework. The enforcement logic is clearly designed to favor the allow conditions to minimize the risk of false positives, maintaining a smooth transaction flow for legitimate payments.
