Calendar

Create Calendar Event

Creates either a Task or an Appointment for the target lead, selected by the 'type' field (case-insensitive TASK / APPOINTMENT). Notes: - Caller must have manage permission on the lead; otherwise 400 PERMISSION_DENIED (20017). - type, leadId, content, startAt and endAt are required. taskWay is additionally required when type = TASK. - startAt and endAt must be later than the current server time. - The returned data.id is a composite string ('<numericId>-task' or '<numericId>-appointment') and must be used as-is when updating, finishing or deleting this entry. - When startAt and endAt are both exactly midnight (00:00:00) in their declared offsets, an appointment is automatically marked as all-day.
