As part of Flow our system allows you to build rules which use decisions and scores from anti-fraud services. Flow rule with an anti fraud decision You can use these scores and decisions for card transactions to evaluate the risk of a transaction and take appropriate actions to, for example, force 3-D Secure, decline a transaction, or route to a specific payment service.

​
How does it work?

For every transaction, your Primary anti-fraud service will only be called once. When a request is made for a transaction, your active anti-fraud provider will only be called once, assuming a rule is triggered for which an anti-fraud score or decision is the condition. This feature will prevent incurring any extra cost by calling your anti-fraud service multiple times, or calling your service unnecessarily if the rule is not triggered.
