Notes

When accessed with an OAuth access token, `email` fields are recursively removed from the response JSON (they are retained for session-authenticated dashboard access).

enabledMeetings, enabledChat, enabledReferralTree (invitations) and enabledConferenceMode can only be turned on through the platform administration (admin) API. Values for them sent to this endpoint are ignored, and they are always false on create. The only feature toggles an event manager can change are enabledTickets and enabledSideEvents. Read the current values from GET /manage/events/:eventId.
