User Identity APIs in Kotlin SDK

This guide covers the user identity APIs that help you retrieve the following parameters persisted by the Kotlin SDK:

• Anonymous ID
• User ID
• User traits

Fetch user ID

The SDK assigns a unique userId when an identify event is triggered. This parameter uniquely identifies a user within the database after they log in or sign up.

The following snippet highlights how to obtain the user’s userId:

val userId = analytics.userId

String userId = analytics.getUserId();

The above snippet returns the following information:

Fetch anonymous ID

anonymousId is a unique identifier automatically generated by the SDK to track unidentified users, for example, users before they log in or sign up. This ID persists across sessions and allows tracking user behavior before they are identified explicitly.

The following snippet highlights how to obtain the user’s anonymousId:

val anonymousId = analytics.anonymousId

String anonymousId = analytics.getAnonymousId();

The above snippet returns the following information:

Fetch user traits

The SDK uses the traits object to store any additional user attributes, for example, name, email, custom properties, etc. associated with an identify event. These traits allow for richer user profiling and segmentation.

The following snippet highlights how to obtain the user’s userId:

val traits = analytics.traits

Map<String, Object> traits = analytics.getTraits();

The above snippet returns the following information:
