# On ad set effective status changed

> Starts when Meta reports that an ad set's effective status changed.

`metaAds.onAdSetEffectiveStatusChanged` starts when Meta reports that an ad set's effective status changed.

```ts automations/meta-ads-on-ad-set-effective-status-changed.automation.ts theme={null}
import { automation } from "automate.ax"
import { metaAds } from "automate.ax/meta-ads"

export default automation("On ad set effective status changed", () => {
  const event = metaAds.onAdSetEffectiveStatusChanged({
    adAccountId: "123456789",
  })
  metaAds.getAdAccount({ adAccountId: event.accountId })
})
```

The event identifies the ad set in `value.objectId`. Read it to obtain the current effective status. Optional `account` selects a static project account binding.
