# Add a note to a ticket > Leaves context on a ticket. Source: https://www.hey.support/docs/api/tickets/add-ticket-note --- 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. ## Path parameters ## Request body ## Response `201` ### Errors * `400` — Invalid body * `401` — Missing or invalid API key * `404` — Not found * `429` — Rate limit exceeded Every error shares [one envelope](/docs/api/errors). ## Example ```bash curl -X POST \ https://www.hey.support/api/v1/tickets//notes \ -H 'Authorization: Bearer hs_live_…' \ -H 'Content-Type: application/json' \ -d '{"body":""}' ```
