# Update a calendar event

`PATCH /calendar_event/{id}`

Update a calendar event for a patient. Attribute `all_day` must be true and `end_at` cannot be specified for `plan-check-in` event type. To mark a calendar event as 'completed', set `completed_at` and `completed_by` to desired values.  To mark a completed calendar event as 'not completed', set `completed_at` and `completed_by` to `null`. Attendees can be added or removed, but response status cannot be updated. Use the calendar event response api for response status updates instead.
