An entity represents a person or thing that's performing the event. An entity type classifies the entity. Example classifications include customer, merchant, user, or account. You provide the entity type (ENTITY_TYPE) and an entity identifier (ENTITY_ID) as part of your event dataset to indicate the specific entity that performed the event.
Amazon Fraud Detector uses the entity type when generating fraud prediction for an event to indicate who performed the event. The entity type you want to use in your fraud predictions must first be created in Amazon Fraud Detector and then added to the event when creating your event type.
