# On event

> Run an automation for any supported MillionVerifier notification.

`millionVerifier.onEvent` runs for credit and bulk-file notifications.

```ts automations/millionverifier-on-event.automation.ts theme={null}
import { automation } from "automate.ax"
import { millionVerifier } from "automate.ax/millionverifier"

export default automation("Handle MillionVerifier events", () => {
  millionVerifier.onEvent()
})
```

`account` selects a static MillionVerifier API-key binding and defaults to the project binding. Runtime signals cannot select the watched account.

Returns a discriminated union with `reason`: `noCredit`, `lowCredit`, `fileReady`, or `fileDeletionScheduled`. Narrow on `reason` to access credit or file details.

Complete the manual callback setup in the [MillionVerifier overview](/reference/integrations/millionverifier/index) after deployment.
