# CampaignTargetingUpdate

Targeting configuration for updating an existing campaign’s supply source, placement, and geographic markets.

```
object CampaignTargetingUpdate
```

## Discussion

The `CampaignTargetingUpdate` object is the update-time counterpart to [`CampaignTargeting`](/documentation/Apple-Ads-Platform-API/CampaignTargeting). The `supplySource`, `supplyPlacement`, and `countryOrRegion` fields are all optional and nullable. Only the fields you supply are changed, and any omitted field retains its current value. Each field uses a [`TargetingDataUpdate`](/documentation/Apple-Ads-Platform-API/TargetingDataUpdate) object to express `include`/`exclude` changes for that dimension.

### Example

```json
{
  "supplySource": {
    "include": ["APPSTORE"],
    "exclude": null
  },
  "supplyPlacement": {
    "include": ["APPSTORE_SEARCH_RESULTS", "APPSTORE_TODAY_TAB"],
    "exclude": null
  },
  "countryOrRegion": {
    "include": ["US", "CA"]
  }
}
```
