2026-08-20 Calendar API

  • Calendars now always report an is_epilot_default flag indicating whether a calendar is the organization's default calendar — returned by GET /v1/calendar, POST /v1/calendar, POST /v1/calendar/sources/outlook, and GET/PATCH /v1/calendar/{calendar_id}
  • calendar_id is no longer required when creating an event through POST /v1/calendar/events — the event is placed in the default calendar when it is omitted
  • DELETE /v1/calendar/{calendar_id} can now answer with 409 when the calendar cannot be deleted
