## 2026-09-14: `v1` published

First public version of the contract. Everything below is the initial commitment.

**Endpoints**: robots, channels, automation rules, media, usage, and a read-only webhook
configuration endpoint.

**Webhook events**: `message`, `message.generating`, `chat`, `reaction`, `is_typing`.

**Decisions worth calling out**, because each one changes what you build:

| Decision                                | Why                                                                 |
| --------------------------------------- | ------------------------------------------------------------------- |
| No writable webhook endpoint            | A stolen key must not be able to redirect your event stream         |
| Webhook auth token is **yours** to set  | It only gates your own endpoint, so waiting on us would be friction |
| Rate limit **queues**, never drops      | A dropped automated reply is a lost customer conversation           |
| `context_reset` is not deletion         | Treating it as deletion discards a transcript we still hold         |
| `follows_business: null` fails **open** | `null` is "Meta did not confirm", not "does not follow"             |
| `404`, not `403`, for others' resources | A `403` would confirm the id exists                                 |

## How changes are announced

| Change                          | You hear about it via                                            |
| ------------------------------- | ---------------------------------------------------------------- |
| A new field, event, or endpoint | This page. **Not breaking**, so ignore what you do not recognise |
| A removed or renamed field      | Your account manager, in advance                                 |
| A route going live              | The pre-release banner disappears from that page                 |

See [Versioning & stability](/documentation/reference/versioning-stability) for the full rules on what counts as breaking.
