# Event catalogue

Every webhook event type, with its record type, version and meaning, and the delivery payload with an example.

Every event type a webhook endpoint can subscribe to, with its version and what it means. It is the same list as the `Event catalogue` on the `Webhooks` tab in Backed. An endpoint receives only your organisation’s events, and only the types it is subscribed to. How to check each delivery is in [Webhook signature verification](https://backed.giving/developers/guides/webhook-signatures.md).

## The payload

Each delivery is a `POST` with this JSON body and the `Backed-Signature`, `Backed-Event-Id` and `Backed-Event-Type` headers. The body is a reference, not a copy of the record: it never carries form answers, bank details or contact details. Read the record through the API at `data.url` for those.

Payload fields:

| Field | Type | What it holds |
| --- | --- | --- |
| `id` | `string` | The event’s id, as the `Backed-Event-Id` header. The same on every retry and replay. |
| `type` | `string` | The event type, as the `Backed-Event-Type` header. |
| `version` | `integer` | The event type’s version. |
| `occurred_at` | `string` | When it happened, in UTC. |
| `organisation` | `string` | Your organisation’s id. |
| `data` | `object` | The record the event is about. |
| `data.record_type` | `string` | The record’s type: the catalogue’s `Record type`. |
| `data.record_id` | `string` | The record’s id. |
| `data.url` | `string \| null` | The record’s address in the read API on your organisation’s host, or `null` where the API serves no such record. |

Example payload:

```json
{
  "id": "918273",
  "type": "rounds.funding_round.published",
  "version": 1,
  "occurred_at": "2026-11-09T01:00:00.000Z",
  "organisation": "17",
  "data": {
    "record_type": "funding_round",
    "record_id": "42",
    "url": "https://your-org.backed.giving/api/v2/funding_rounds/42"
  }
}
```

## Event types

186 event types, by name. `webhook.test` is sent only by `Send Test` on an endpoint’s page.
