# Categories Cache

The Shopping App backend caches category data to speed up catalog browsing within Shopping App.

The following data is cached:

- The category tree that forms the navigation.
- For each category, the backend caches the **order** in which products appear in this category, the available filters, and sorting options.

The cache is used when browsing the product lister view in the Shopping App.

> [!TIP]
> **Note**
> 
> Product data (such as the product name, pricing info, and more) is stored in a separate cache. The categories cache **only** stores the order of products.

## Refreshing the categories cache

The categories cache can be refreshed in 3 ways: automatically on a platform schedule, via NewStore Studio, or using an API.

By default, this cache is refreshed regularly throughout the day on a preferred, configurable schedule (set to every hour, every 3 hours, or every 8 hours). Additionally, the categories cache is refreshed as part of any manual cache refreshes performed or scheduled in NewStore Studio.

### Using an API to refresh the categories cache

You can also disable the scheduled refreshes and use an API to refresh the categories cache. By integrating the API call into a catalog import or export process, for example, Shopping App can be kept as up-to-date as possible.

The Shopping App backend offers an API that can be used to refresh the categories cache. Calling the API endpoint starts a background job that refreshes all cached category data.

Refer to the documentation for the API [here](https://docs.newstore.net/api/integration/consumer-app/jobs#tag/Jobs/paths/~1jobs~1reindex-categories/post). To use this API you’ll need:

- Your merchant ID
- Credentials for calling this API

You can request for the merchant ID and credentials from your Omnichannel Success Manager.
