Handle risk rule notifications

Notifications inform you when payment requests trigger risk rules.

Notifications are how we inform your server of payment eventsmodifications, and newly available reports. For risk, notifications inform you when risk rules have been performed. This information is also returned in the payment response.

This setting is not turned on by default. To configure your account to return the triggered risk rules and their results, or to configure your account for version 2, contact our Support Team. Upgrading to version 2 will affect the format of both notifications and payment responses.

Risk rule result line format

Version 1

For version 1, risk rule result lines are in the format: 

fraudCheck-[risk rule ID]-[risk rule name]

For example:


For a list of the risk rule names, see the risk rule name reference.

Notification example


API response example


For more information on the fields returned in the API response, see our API explorer.

Version 2

For version 2, we've added the ability to break custom risk rules into numerous, more specific, rules. This allows you to track when specific risk rules are triggered.

Standard risk rule result lines are in the same format as version 1. Custom risk rule result lines are in the format: 

fraudCheck-[risk rule ID]-CustomFieldCheck-[Rule name]

For example:


For a list of the risk rule names, see the risk rule name reference.
