Handle risk rule notifications

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

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:

fraudCheck-82-CustomFieldCheck

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

Notification example

<entry>
      <string>fraudCheck-82-CustomFieldCheck</string>
      <string>30</string>
</entry> 

API response example

{
   "FraudCheckResult":{
      "accountScore":30,
      "checkId":82,
      "name":"CustomFieldCheck"
   }
},

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:

fraudCheck-82-CustomFieldCheck-testRule2

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

Notification example

<entry>
      <string>fraudCheck-82-CustomFieldCheck-testRule1</string>
      <string>10</string>
</entry>
<entry>
      <string>fraudCheck-82-CustomFieldCheck-testRule2</string>
      <string>10</string>
</entry>
<entry>
      <string>fraudCheck-82-CustomFieldCheck-testRule3</string>
      <string>10</string>
</entry>

      "accountScore":10,
      "checkId":82,
