# Auto Store

The Chartboost Exchange Auto Store is designed to enhance user experiences in ad-driven campaigns. It leverages the iOS [`SKStoreProductViewController`](https://developer.apple.com/documentation/storekit/skstoreproductviewcontroller){:target="_blank"} to display a store modal within the app environment, enabling users to download apps without leaving the current app. This integration builds on the [SKOverlay](/en/partners/exchange/skoverlay-support/) feature, providing a more seamless and optimized ad-driven campaign experience.

  <b>Note:</b> Auto Store is only available for full-screen VAST ads on iOS with an App Store bundle and using a minimum version of <a href="/en/monetization/integrate/ios/get-started/">Chartboost iOS SDK 9.1.0</a>.
</div>


## Integrating Auto Store

Auto Store is triggered after the SKOverlay video ends and only if `autostore` parameter is enabled. 
- To enable Auto Store, set `autostore` in `BidResponse.seatbid.bid.ext` to `1` (enabled). 
- To enable click tracking with Auto Store, set `autostoreclick` in `BidResponse.seatbid.bid.ext` to `1` (enabled).

When Auto Store is triggered, the app store will display within the app. Upon closing the Auto Store, an end card will then display.
