# CampaignTargetingUpdate.SupplyPlacement

The specific placement within a supply source where an existing campaign’s ads are eligible to appear.

```
object CampaignTargetingUpdate.SupplyPlacement
```

## Discussion

The `supplyPlacement` field is **include-only**; setting `exclude` has no effect. Omit to leave unchanged. Each placement belongs to exactly one [`CampaignTargetingUpdate.SupplySource`](/documentation/Apple-Ads-Platform-API/CampaignTargetingUpdate/SupplySource-data.dictionary):

|Value                    |Supply source|Placement                |
|-------------------------|-------------|-------------------------|
|`APPSTORE_SEARCH_RESULTS`|`APPSTORE`   |App Store Search results |
|`APPSTORE_SEARCH_TAB`    |`APPSTORE`   |App Store Search tab     |
|`APPSTORE_TODAY_TAB`     |`APPSTORE`   |App Store Today tab      |
|`APPSTORE_PRODUCT_PAGES` |`APPSTORE`   |App Store Product pages  |
|`MAPS_SEARCH_RESULTS`    |`MAPS`       |Apple Maps Search results|
|`MAPS_SEARCH_HOME`       |`MAPS`       |Apple Maps Search home   |

Uses the [`TargetingDataUpdate`](/documentation/Apple-Ads-Platform-API/TargetingDataUpdate) `include`/`exclude` shape.
