Represents user interaction event information sent using the PutEvents API.

Constructors

Event({required String eventType, required DateTime sentAt, String? eventId, double? eventValue, List<String>? impression, String? itemId, Object? properties, String? recommendationId})

Properties

eventId → String?
An ID associated with the event. If an event ID is not provided, Amazon Personalize generates a unique ID for the event. An event ID is not used as an input to the model. Amazon Personalize uses the event ID to distinquish unique events. Any subsequent events after the first with the same event ID are not used in model training.

eventType → String

eventValue → double?
The event value that corresponds to the EVENT_VALUE field of the Interactions schema.
