get_event_prediction_metadata(**kwargs)¶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
response = client.get_event_prediction_metadata(
eventId='string',
eventTypeName='string',
detectorId='string',
detectorVersionId='string',
predictionTimestamp='string'
)
[REQUIRED]
The event ID.
[REQUIRED]
The event type associated with the detector specified for the prediction.
[REQUIRED]
The detector ID.
[REQUIRED]
The detector version ID.
[REQUIRED]
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.

Account Takeover Insights (ATI) model uses event variables from the login data you provide to continuously calculate a set of variables (aggregated variables) based on historical events. For example, your ATI model might calculate the number of times an user has logged in using the same IP address. In this case, event variables used to derive the aggregated variables are IP address and user .
