Identify Users

Identify a user

Each time a page loads for a user you can identify, you'll want to call the FS.identify function to associate your own application-specific id with the active user.

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 30 calls per page per minute with a burst limit of 10 calls per second.

Additional Information

• Identifying users
• If you only want to pass in userVars you can use the FS.setUserVars function.
