Identify User

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 Map<String, ?> optional

    A map 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

public static void FS.identify(String uid, Map<String, ?> userVars);

Example Invocation

Map<String, String> userVars = new HashMap<>();
userVars.put("displayName", "Ada Lovelace");
userVars.put("email", "ada@example.com");
FS.identify("462718483", userVars);
