Book through the same capacity rules as the Talki assistant, at the location of the service (the main location without one). A service of an inactive location is refused with location_inactive. Requires Idempotency-Key. Requires appointments:write. Limited to 120 requests per minute per account (API key) or per installation (OAuth).

Header Parameters

Section titled “Header Parameters”
Talki-Version
string
Example
2026-10-01

Serve 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.

Idempotency-Key
required
string
<= 255 characters

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.

Successful Response

Media typeapplication/json
Appointment

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
id
required
Id

Opaque Talki appointment identifier.

string
location_id
required
Location Id

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.

string
status
required

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.

string
Allowed values: active cancelled
client
required
AppointmentClient

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.

object
contact_id
required
Any of:
string
name
required
Name

First name the booking was taken under.

string
surname
required
Surname

Surname the booking was taken under.

string
phone_number
required
Any of:
string
service
required
Any of:
ServiceRef

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.

object
id
required
Any of:
string
name
required
Any of:
string
start_at
required
Start At

Start of the booking, RFC 3339 UTC.

string format: date-time
end_at
required
End At

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.

string format: date-time
quantity
required
Quantity

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.

integer
call_id
required
Any of:
string
notes
required
Any of:
string
created_at
required
Created At

When the booking was written, RFC 3339 UTC.

string format: date-time
updated_at
required
Updated At

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.
