  title: Amazon Fraud Detector Author Rule
  summary: Create a DETECTORPL rule for a detector and read the detector's rules back to confirm it.
  description: >-
    Encodes a piece of fraud business logic as a rule. The workflow creates a
    rule on an existing detector using a DETECTORPL expression and one or more
    outcomes, then lists the detector's rules to confirm the new rule was
    registered. Each step spells out its request inline so the flow can be read
    and executed without opening the underlying OpenAPI description.

    Creates a DETECTORPL rule with an expression and outcomes on an existing
    detector, then reads the detector's rules back to confirm registration.
