# API Changelog — Additive, Never Breaking

> Release history for the ImageToTable.ai v1 API — every new field or endpoint is additive and never a breaking change, so this log tracks what's new without implying you need to update existing integrations.

Our versioning policy: new fields and new endpoints are additive and never count as a breaking change under the `/api/v1/` prefix — removing or changing the meaning of an existing field would be a v2. That means you can treat every entry below as "here's what's new," not "here's what might break your integration."

## 2026-07-20

- **Batch webhooks now re-arm automatically when you reprocess a batch.** If you upload more documents into a batch that already notified you once and call `process` again, you'll now get notified again when that new wave finishes — no need to re-`PUT` the webhook. See the [Webhooks guide](/developers/guides/webhooks#reprocessing-a-batch). If your integration currently re-registers the webhook before each wave as a workaround, it's safe to stop — that call was never actually re-arming anything.
- **Bbox annotation jobs now deliver a webhook event.** A `document.bbox_completed` event fires on the document's batch webhook when a bbox job reaches a terminal status — previously bbox completions produced no notification at all, regardless of registration. See the [Webhooks guide](/developers/guides/webhooks#event-envelope).
- **`remaining_batch_capacity` added to `POST /documents` responses.** Tells you how many more documents this batch can accept before hitting your plan's max batch size, without a separate call to `GET /account`.
- **`document.bbox_completed` deliveries are now claimed atomically, same as `batch.completed`.** A bbox job whose row-groups finish within moments of each other on different threads used to sometimes fire two separate deliveries for what was logically one completion — you should no longer see that. If your integration was deduping these events by `data.group_batch_id` as a workaround, that's harmless to keep doing.

## 2026-07-16

- **v1 API launched.** Public release of `/api/v1/`, covering Documents, Batches, Templates & Fields, Webhooks, and Account resources for the `table` (structured field extraction) processing mode. See [API Overview](/developers/) to get started.
