# Dynamically display items in your online store

The app provides a secure API, which can be used to extend your online store with item lookup capability, similar to the search functionality on the "[Sold items](/serializer-product-tracking/getting-started/item-management/manage-sold-items/view-all-sold-items.md)" page in the app. This may be useful to merchants wanting their customers to verify the authenticity of their purchased items.

{% hint style="info" %}
To implement item search functionality on the storefront, basic knowledge of Javascript and Shopify Liquid programming languages is required. See the [development API reference](/serializer-product-tracking/getting-started/sharing-and-integration/development-api-reference/app-proxy-rest-api.md) for more details.
{% endhint %}

## write\_app\_proxy access scope

In order to provide the items lookup capability, the app needs the `write_app_proxy` access scope, i.e. a permission to 

"*View and edit store data*

*Edit your Online Store*

*Online Store page content on a path controlled by the app*"

**Unfortunately, the access scope is required even if your store doesn't rely on the app proxy.**&#x20;

According to [Shopify's documentation](https://shopify.dev/docs/apps/build/online-store/display-dynamic-data#liquid-response), "*App proxies support* [*Liquid*](https://shopify.dev/docs/api/liquid)*, Shopify's template language. An app proxy response that contains Liquid will be rendered with store data into HTML like it was part of the store's theme.*"

Please note that even though the app requires the access scope, **it doesn't automatically make any changes to your storefront's content, even if your online store uses the app proxy**. The API only returns data in JSON format and not Liquid. However, you can implement custom solutions, which would present such data to your customers.&#x20;
