# AppSupportedLanguages

App supported and default languages for an App Store country or region.

```
object AppSupportedLanguages
```

## Discussion

The `AppSupportedLanguages` object provides metadata about a supported advertising market, including the country name, its ISO 3166-1 alpha-2 `countryCode`, and the language settings relevant for ad delivery. The `adsSupportedLanguages` field lists all languages available for ads in that market. The `adsDefaultLanguages` field lists the languages the system applies automatically when you don’t set explicit language targeting.

The [`Query Supported App Languages`](/documentation/Apple-Ads-Platform-API/Query-Supported-App-Languages) endpoint returns this object, which you use to validate locale choices before setting them on creatives or ad groups.

### Example

```json
{
  "name": "United States",
  "countryCode": "US",
  "adsSupportedLanguages": [
    {
      "language": "en",
      "languageCode": "en-US"
    },
    {
      "language": "es",
      "languageCode": "es-US"
    }
  ],
  "adsDefaultLanguages": [
    {
      "language": "en",
      "languageCode": "en-US"
    }
  ]
}
```
