Multi-step API workflows described with the Arazzo specification.
Amazon Fraud Detector Author Rule
Create a DETECTORPL rule for a detector and read the detector's rules back to confirm it.
ARAZZOAmazon Fraud Detector Bootstrap Event Type
Create fraud and legit labels, define an event type that uses them, then confirm the event type exists.
ARAZZOAmazon Fraud Detector Decommission Detector
Inspect a detector's rules and then delete the detector, branching when rules still block deletion.
ARAZZOAmazon Fraud Detector Detector Pipeline
Define an event type, create a detector and a rule, then score a sample event against the detector.
ARAZZOAmazon Fraud Detector Inventory Models and Detectors
List models for an event type, then list detectors and tag a chosen detector with its model count.
ARAZZOAmazon Fraud Detector Provision Model and Detector
Define an event type, create an ML model and a detector on top of it, then confirm the detector exists.
ARAZZOAmazon Fraud Detector Score Event and Tag
Score an event against a detector and branch on the returned model score to tag the detector accordingly.
ARAZZOAmazon Fraud Detector Tag and Audit Resource
