Add a note to a ticket

A note never leaves the building — not to the customer, not to their status page, not to a GET of this ticket. Pass kind: "reply" to write to the customer instead, which emails them exactly as a reply from the desk would; it has to be asked for by name so nobody reaches it by accident.
