Identify Users

Identify a user

Whenever a user logs in, call the FS.identify() function to associate your own application-specific id with the active user for current and future sessions.

Parameters

uid String required

A string containing your unique identifier for the current user.

userVars Map optional

A Map with key/value pairs that provides additional information about your user.

Special Fields

These are reserved field names that can be included in userVars that have special meaning and usage.

displayName String optional

The value of displayName is displayed in the session list and on the user card in the app.

email String optional

The value of email is used to let you email the user directly from the app. The email value can also be used to retrieve users and sessions via the Get User and List Sessions HTTP APIs.

Re-identification

Fullstory doesn't let you change the identity of a user once they have been assigned a unique user ID using FS.identify. If you attempt to change the user id of an identified user, Fullstory will recognize the new user ID and automatically split the session into a new session.

Limits

• Sustained calls are limited to 12 calls per minute, with a burst limit of 5 calls per second.
