How do I manage custom risk rules?

You can create your own custom risk rules next to using standard risk rules. Custom risk rules are a RevenueProtect premium feature. You can use these rules to influence the risk score of a transaction, send it to case management, or use the custom rule in combination with Dynamic 3D Secure.

Create a custom risk rule

To build your custom risk rules:

1. Choose risk variables: understand which variables you can use in custom risk rules, or create custom fields. You can create your own fields, or choose any of the risk fields provided by Adyen as variables in your custom rule. Many fields that can be included in a payment request can also be used in custom rules. If you want to use any of these fields in your custom rule, you must provide the required field, and assign a value to it in the payment request.
2. Create the rule: set rule conditions to define when the rule should trigger. First you decide when you want to trigger the rule: before or after authorization. Then you build the rule around custom fields or Adyen-provided fields, using the available operators.
3. Assign an action to the rule: define what should happen to the transaction when the rule triggers. You can modify the risk score of the transaction, or send it to case management for manual review.

You can increase or decrease the risk score when the custom rule triggers. The risk score you configure depends on the scenario you are trying to achieve with your custom rule: block or trust a transaction. When the total risk score of a transaction reaches 100, it will be blocked.

For more advanced scenarios, you can also create custom lists and custom list comparisons. Visit our docs page on Custom rules for more details.
