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.
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.
| 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. |
