# On ad-group asset updated

> Run an automation when a Google Ads ad-group asset link is updated.

`googleAds.onAdGroupAssetUpdated` emits link changes observed after the trigger establishes its baseline. Existing changes aren't replayed.

## Example

```ts theme={null}
import { automation } from "automate.ax"
import { googleAds } from "automate.ax/google-ads"

export default automation("On ad-group asset updated", () => {
  const change = googleAds.onAdGroupAssetUpdated({ customerId: "1234567890" })

  googleAds.getCustomer({ customerId: change.customerId })
})
```

## Options

Set the static `customerId` to the 10-digit Google Ads customer, with or without dashes. Set `loginCustomerId` when a manager account authorizes the client. `account` selects a named Google connection. Signals can't select these values at runtime.

## Trigger data

Returns `{ customerId, event }`. The event identifies the asset-link resource, operation, change time, changed-field mask, and available metadata. `oldResource` and `newResource` contain the changed fields Google provides.

Automate.ax polls once per minute. Google can delay change events, so delivery is not immediate. Google only exposes change history from the previous 30 days and caps a query at 10,000 rows.
