Identify a User

Call setUserID to identify your users when recording a session. This method allows you to associate your internal-user-id with the session being recorded. The identity of the user can be changed anytime during the session by calling setUserID. However, OpenReplay will only keep the last communicated user ID.


You can also set the userID in the constructor and make sure it's called right after the tracker starts.

const tracker = new OpenReplay({
projectKey: PROJECT_KEY,
onStart: () => { tracker.setUserID(''); }
