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 object optional

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

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.

Additional Information
