# On Vercel project domain unverified

> Start an automation when a Vercel project domain becomes unverified.

`onVercelProjectDomainUnverified` emits when a previously verified project domain loses verification.

```ts automations/watch-unverified-vercel-project-domains.automation.ts theme={null}
import { automation } from "automate.ax"
import { onVercelProjectDomainUnverified } from "automate.ax/vercel"

export default automation("Watch unverified Vercel project domains", () => {
  const event = onVercelProjectDomainUnverified()
  event.transform(({ payload }) => ({
    domain: payload.domain.name,
    projectId: payload.project.id,
  }))
})
```

Optional static `account` defaults to the project's Vercel OAuth binding.

## Trigger data

Returns the [project-domain event shape](/reference/integrations/vercel/triggers/on-project-domain-event), narrowed to `type: "project.domain.unverified"`.
