cancel_event
ActiveTool of Chronary
Delete or cancel an event from a calendar. Use this to remove, cancel, or delete any scheduled event or appointment. The event is marked cancelled and excluded from future availability calculations. For a recurring series, pass `occurrence_start` to cancel just that one occurrence (the series continues); omit it to cancel the whole series. `calendar_id` is optional — if omitted the calendar is looked up from the event. Provide `calendar_id` to fail fast on cross-calendar typos.
