# extraction.updated

POST 

Fires when a stored extraction is rewritten in place after `extraction.ready` already fired for that document: what you fetched is stale. Re-fetch and compare `extraction_version` against `previous_extraction_version`.

## Request

### Headers

- `SpreadSpace-Signature` (string, required) — Signature over the exact request body: `t=<seconds since the Unix epoch>,v1=<lowercase hex HMAC-SHA256 of "{t}.{body}" keyed with your endpoint's signing secret>`. Verify it before trusting the body, and reject a `t` more than five minutes from your own clock. During a secret rotation both the new and the previous secret verify for 24 hours; each delivery is signed with exactly one.
- `SpreadSpace-Event-Id` (string, required) — The event id, identical to the body's `id`. Stable across retries and replays, and shared by every endpoint one event fans out to. Delivery is at-least-once, so dedupe on it.

### Payload

- `id` (string, required) — Event id: `evt_` plus 24 lowercase hex characters. Also sent as the `SpreadSpace-Event-Id` header. Stable across retries and replays, so dedupe on it.
- `type` (enum, required) — Always this event type on this body.
  - Allowed values: `extraction.updated`
- `created` (long, required) — Seconds since the Unix epoch at which the event was created server-side. Seconds, not milliseconds. Deliveries are not ordered; reconcile on this.
- `tenant_id` (string, required) — The workspace the event belongs to. Reject a delivery whose tenant does not match the endpoint you registered.
- `livemode` (boolean, required) — `true` for live activity, `false` for test mode (an `ss_test_` key or the sandbox simulator). Branch on it to route test deliveries to a staging handler.
- `data` (ExtractionUpdatedPayload, required) — The `data` object on an `extraction.updated` delivery, sent when a stored extraction is rewritten after `extraction.ready` already fired for that document. What you fetched on `ready` is now stale: re-fetch the document, and the new read carries `extraction_version`. Today the only cause is an enrichment landing after the ready grace window. Identifiers only: no figures and no personal data, like every sibling payload.

## Types

### ExtractionUpdatedPayload

The `data` object on an `extraction.updated` delivery, sent when a stored extraction is rewritten after `extraction.ready` already fired for that document. What you fetched on `ready` is now stale: re-fetch the document, and the new read carries `extraction_version`. Today the only cause is an enrichment landing after the ready grace window. Identifiers only: no figures and no personal data, like every sibling payload.

- `extraction_id` (string, required) — The extraction record to fetch. Equal to `document_id` today.
- `document_id` (string, required) — The extracted document.
- `job_id` (string, required) — The document package (job) the document was uploaded in.
- `borrower_id` (string, required) — The borrower that owns the loan.
- `loan_id` (string, required) — The loan the document belongs to.
- `document_type` (string, required) — What the document was classified as, using the same values the sibling events report.
- `extraction_version` (integer, required) — The revision the stored extraction is at now, which is what a fresh fetch returns.
- `previous_extraction_version` (integer, required) — The revision that was current before this rewrite (the one `ready` may have announced).
- `reason` (enum, required) — Why the extraction changed: `enrichment` when an enrichment landed, or `rewrite` for any other change to the stored payload.
  - Allowed values: `enrichment`, `rewrite`
- `updated_at` (datetime, required) — Server-side wall-clock time the rewrite was persisted.
