2026-10-01Serve this one request at the given dated contract version instead of the credential’s pin. An unsupported value is refused with 400 unsupported_version, never downgraded.
Unique key for this logical write. Reuse it only when retrying the same method, path, query and body. Required on appointment writes, on creating a service, a resource, a closure, a tag, a caller rule or a document, and on teaching the assistant; optional on every other write. Retained for 24 hours: a retry with the same key gets the first response again, marked Idempotency-Replayed: true, and a refusal that holds until the state changes (a time taken, a list full) is replayed too. A response a retry can change is not kept when the request saved nothing, and the retry runs the request again: a 400 asking for a different request (invalid_parameter, invalid_cursor, export_too_large, unknown_scenario, no_services_requested, stay_too_short, stay_too_long, stay_dates_invalid), a 415, a 409 request_conflict, document_not_ready or check_in_progress, a 412, a 429 and a 5xx.
Example
reschedule-crm-1042Request Bodyrequired
Section titled “Request Bodyrequired”A partial edit of a booking. Every field is optional, and an omitted field is left unchanged, not cleared. A move that does not fit is refused with a conflict code; nothing is booked. A booking never changes location.

Section titled “ Responses ”Successful Response
One booking in the account’s calendar. This object is the record: a connected Google or Outlook calendar holds a copy, so reconcile against this object, not against the provider calendar.
object
Opaque Talki appointment identifier.
The location the booking is at (GET /v1/locations), the one its service belongs to. Never null, and it never changes: moving a booking keeps its location.
active or cancelled. A cancelled appointment is retained rather than deleted, and can be restored — expect to see an id return to active via appointment.updated.
Who the booking is for. Always present; contact_id and phone_number are null when Talki has no number for the client. The name is the one the booking was taken under, exactly as the owner sees it, and may come from what the assistant heard on the call.
The service an appointment is for, with enough to display it. Once the service is deleted, id is null and name is the one it was booked under. Fetch the full service with services:read.
Start of the booking, RFC 3339 UTC.
End of the booking, RFC 3339 UTC. For a multi-day stay this is the check-out moment, so the span covers the whole booking rather than one night.
Party size the booking carries — covers, people, items — for a service that asks for one (asks_quantity on GET /v1/services). Always 1 for a service that does not, so you can read it unconditionally. It is the booking’s total, not a breakdown per resource or unit.
When the booking was written, RFC 3339 UTC.
Last change to the booking, RFC 3339 UTC. Show it to a human as “last modified”; do not sync on it: changes do not become visible in updated_at order, so a watermark on it can skip a booking permanently. Use the change feed’s next_cursor instead.
