# On Resend domain event

> Run an automation for any Resend domain lifecycle event.

`resend.onDomainEvent` handles `domain.created`, `domain.updated`, and `domain.deleted`.

```ts automations/watch-resend-domains.automation.ts theme={null}
import { automation } from "automate.ax"
import { resend } from "automate.ax/resend"

export default automation("Watch Resend domains", () => {
  resend.onDomainEvent().transform(({ event, id, name, status }) => ({
    id,
    name,
    status,
    type: event.type,
  }))
})
```

The signal includes the domain ID, name, status, region, DNS records, optional sending and receiving capabilities, and original `event` envelope.
