Google Calendar has a new event type called "Out of office" that automatically will decline any events it is placed over and others that come in during the scheduled time of the event.
I inspected one of these event objects via the API and briefly checked the Google Calendar API documentation to see if there was a way to create these programmatically. I work on a system that schedules events on people's calendars when they are going to be out of the office as all day events to provide visibility to the rest of the staff. I would like to change these to be true Out of office event types if its possible via the API.
