Update label

If your event dataset is stored with Amazon Fraud Detector, you might need to add or update labels for the stored events, such as when you perform an offline fraud investigation for an event and want to close the machine learning feed back loop.

You can add or update labels for stored events using the update-event-label command, using the UpdateEventLabel API, or using the AWS SDK for Python (Boto3)

The following AWS SDK for Python (Boto3) example code adds a label fraud that is associated with the event type registration using the UpdateEventLabel API.

import boto3
fraudDetector = boto3.client('frauddetector')

fraudDetector.update_event_label(
            eventId        = '802454d3-f7d8-482d-97e8-c4b6db9a0428',
            eventTypeName  = 'registration',
            assignedLabel  = 'fraud',
            labelTimestamp = '2020-07-13T23:18:21Z'
)
