How to track anonymous events in Mixpanel

Question

mixpanel documentation states that

tracker.track(user_id, 'Sent Message')

which requires user_id to be the source of the event.

What should I do if the user has not registered it or the event just happens without user interaction? e.g. redirection caused by some dynamic data

Is there a way to track an event (with ruby ​​api) that doesn't match the user?
