API reference/Appointments

Move an appointment

Try it

Moves a pending or booked appointment to another OPEN time (a `key` from list_open_times with appointment_id). Moving confirms it, emails the visitor the new time and resets the reminder. A time someone else holds is 409.

POST/api/v1/sites/{site_id}/appointments/{appointment_id}/move

Authentication

An API key as Authorization: Bearer or x-api-key. It needs the bookings:write scope — set booking hours; confirm, decline, cancel and move appointments (live at once, the visitor is emailed).

bookings:writeChanges the live siteIdempotency-Key requiredMCP tool: move_appointment

Parameters

Named placeholders go in the path; the rest in a JSON body.

site_idstringPath · required
The site's id.1 to 100 characters
appointment_idstringPath · required
The appointment's id.1 to 100 characters
starts_atstringBody · required
The new start: a slot key from list_open_times.

Response

200 with JSON on success (schema on the right). Errors use the standard envelope; a retry with the same Idempotency-Key gets the first answer back (how retries work).
