# RSVP to a Google Calendar invitation

Respond to a Google Calendar invitation (RSVP yes / no / maybe) by its eid, as the signed-in account. Opens the event, sets the Going? response and saves; the organizer is notified automatically. Only works on events you were invited to (that expose the RSVP control) — passing an event you solely organize fails loudly. Returns responded, eid, response.
