Source

Where the change came from: voice (the assistant, during a call), dashboard (a person in the Talki web or mobile app), api (a credential through the API) or system (a rule Talki applied on its own). New values may be added; treat one you do not recognise as unknown.

object

required

The Call object, as the REST API returns it.

object
id
required
Id

Opaque Talki call identifier. Decided when the call arrives: the call.ringing event sent while it rang carries the same id as data.call_id.

string
location_id
required
Location Id

The location the call was for: the one whose Talki number the caller dialled (GET /v1/locations). Never null: a call to the account’s own number, and every call from before locations existed, is the main location’s. It never changes.

string
caller
required
CallCaller

Who called, as far as the account knows. Always present; its fields may be null. display_name is set only for a name the owner entered or imported, never for one the assistant heard.

Any of:

CallTransfer

A hand-over of the call to a person, in the order it happened.

When this record was written, RFC 3339 UTC: after the call ended, so a long call can be written after a shorter call that started later. created_after filters on this field. Do not use it as a sync watermark: records do not become visible in created_at order, so a watermark on it can skip a call permanently. Resume a sync with GET /v1/calls?sync=true and its cursor.

string format: date-time
read_at
required
Any of:
string format: date-time
archived_at
required
Any of:
