Authorizations
Section titled “Authorizations”Parameters
Section titled “ Parameters ”Query Parameters
Section titled “Query Parameters”Maximum number of appointments to return.
Maximum number of appointments to return.
Only the records of this location, an id from GET /v1/locations (inactive ones included). Omit for every location: each record carries its location_id. Allowed on the change feed, because a record never changes location; a cursor is then bound to the location it was issued for, and refused with invalid_cursor under another location_id or without one.
Header Parameters
Section titled “Header Parameters”Example
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.
Responses
Section titled “ Responses ”Successful Response
A page of the appointment change feed. next_cursor is your position in the feed: it is returned on every non-empty page, the last included, and an incremental sync resumes from it. Loop while has_more is true.
object
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.
True when another page is available.
