UserMetadata Entity

Since version 9.0.0, the Kotlin SDK supports entities, which are SDK objects that provide operations on endpoints associated with their type. They are designed as first-class citizens to facilitate working with various PubNub APIs.

Certain PubNub API functionality is already exposed via entities, while other may still be available using the pubnub object.

Create UserMetadata

This method returns one local UserMetadata entity.

pubnub.userMetadata(userId: String): UserMetadata
* required
ParameterDescription
userId *
Type: String
The String identifier for a single user metadata object to manage user information.
