# AnalyticsMetadataType
<a name="API_AnalyticsMetadataType"></a>

Information that your application adds to authentication requests. Applies an endpoint ID to the analytics data that your user pool sends to Amazon Pinpoint.

An endpoint ID uniquely identifies a mobile device, email address or phone number that can receive messages from Amazon Pinpoint analytics. For more information about Amazon Regions that can contain Amazon Pinpoint resources for use with Amazon Cognito user pools, see [Using Amazon Pinpoint analytics with Amazon Cognito user pools](https://docs.amazonaws.cn/cognito/latest/developerguide/cognito-user-pools-pinpoint-integration.html).

This data type is a request parameter of authentication operations like [InitiateAuth](API_InitiateAuth.md), [AdminInitiateAuth](API_AdminInitiateAuth.md), [RespondToAuthChallenge](API_RespondToAuthChallenge.md), and [AdminRespondToAuthChallenge](API_AdminRespondToAuthChallenge.md).
