# Overview

You can use virtual items and virtual currency to build an in-game store and configure how it is displayed to users. The following item types are available:

* Virtual items — in-game goods such as weapons, skins, or boosters. Can be sold for real money or virtual currency.
* Virtual currency — in-game currency used to purchase virtual items. Can be sold for real money or virtual currency.
* Virtual currency packages — a fixed amount of virtual currency. Can be sold for real money or virtual currency.

Groups are used to organize items in the catalog. They allow you to logically group items and manage how they are displayed.

Use API calls from the <b>Admin</b> subsection to create, update, and delete items.

Use API calls from the <b>Catalog</b> subsection to retrieve lists of items and display them to users.
