Change appointment
Changes the date, time, service, staff member or notes of an existing appointment.
PATCH https://cotlet.dev/api/v1/planity/appointments/{appointment_id}
write Confirm
Returns the appointment after the change. Only the fields you pass change. It moves the booking of a real client, and the help article does not say whether Planity notifies them, so the agent reads the appointment back to check. By default you confirm each call; you can switch that off for this tool.
