# AppLocaleDetails

Localized content for an app’s Default Product Page.

```
object AppLocaleDetails
```

## Discussion

The `AppLocaleDetails` object represents the localized metadata and asset groupings for a single locale of an app’s Default Product Page (DPP). The `language` (for example, `"en"`) and `languageCode` (for example, `"en-US"`) fields identify each locale entry.
