## Inbox Events

Every inbox event's `data` has `source` and `inbox_id`, plus the IDs and objects that apply to the event. Keys that don't apply are left out, not sent as `null`.

The `thread`, `email`, `draft` and `inbox` objects are loaded when the webhook is sent, not when the change happened, so two quick changes can both show the second state. `email` and `draft` leave out `html` and `text`; fetch the body from the API. Retries keep the same `svix-id` header, so dedupe on it.

 

[`inbox.created`](/docs/webhooks/inboxes/created)

Occurs whenever an **inbox is created**.

 

[`inbox.updated`](/docs/webhooks/inboxes/updated)

Occurs whenever an **inbox's settings change**.
