GetEventPredictionMetadata - Amazon Fraud Detector

GetEventPredictionMetadata

Gets details of the past fraud predictions for the specified event ID, event type, detector ID, and detector version ID that was generated in the specified time period.

Request Syntax

{ "detectorId": "string", "detectorVersionId": "string", "eventId": "string", "eventTypeName": "string", "predictionTimestamp": "string" }

Request Parameters

For information about the parameters that are common to all actions, see Common Parameters.

The request accepts the following data in JSON format.

detectorId

The detector ID.

Type: String

Length Constraints: Minimum length of 1. Maximum length of 64.

Pattern: ^[0-9a-z_-]+$

Required: Yes

detectorVersionId

The detector version ID.

Type: String

Length Constraints: Minimum length of 1. Maximum length of 5.

Pattern: ^([1-9][0-9]*)$

Required: Yes

eventId

The event ID.

Type: String

Length Constraints: Minimum length of 1. Maximum length of 64.

Pattern: ^[0-9a-z_-]+$

Required: Yes

eventTypeName

The event type associated with the detector specified for the prediction.

Type: String

Length Constraints: Minimum length of 1. Maximum length of 64.

Pattern: ^[0-9a-z_-]+$

Required: Yes

predictionTimestamp

The timestamp that defines when the prediction was generated. The timestamp must be specified using ISO 8601 standard in UTC.

We recommend calling ListEventPredictions first, and using the predictionTimestamp value in the response to provide an accurate prediction timestamp value.

Type: String

Length Constraints: Minimum length of 11. Maximum length of 30.

Required: Yes
