AWS API Changes

2020/04/17 - Amazon Fraud Detector - 2 new 4 updated api methods

Changes Added support for a new rule engine execution mode. Customers will be able to configure their detector versions to evaluate all rules and return outcomes from all 'matched' rules in the GetPrediction API response. Added support for deleting Detectors (DeleteDetector) and Rule Versions (DeleteRuleVersion).

DeleteRuleVersion (new)

Deletes the rule version. You cannot delete a rule version if it is used by an ACTIVE or INACTIVE detector version.

If you specifiy ALL_MATCHED , Amazon Fraud Detector evaluates all rules and returns the outcomes for all matched rules.

The default behavior is FIRST_MATCHED .
