# Overview 
Digital Distribution Hub is a new Xsolla solution that aims to connect digital and cash based payments via push payments technology and e-commerce.
This reference combines API endpoints for two Xsolla products: [In-Game Store](https://developers.xsolla.com/doc/in-game-store/) and [Pay Station](https://developers.xsolla.com/doc/pay-station/). There are two base URLs:
* `https://store.xsolla.com/api` for the **Common**, **Catalog**, **Cart**, and **Order** groups.
* `https://ps.xsolla.com` for the **Notifications** group.

API endpoints in the **Catalog** group don’t require authorization.
To work with operations in the **Cart** and **Order** groups, you need to generate a token via [Create user token](https://developers.xsolla.com/digital-distribution-hub/common/user-token/create-user-token).
<div class='note'><b>Note</b><br><br>This reference shows a design of a future API and not a fully functioning interface. Currently, you can try only <b>Catalog</b> and <b>Notifications</b> groups endpoints.
