# Catalog and payments

> Reuse your project's IAP catalog in a webshop and route purchases to your payment providers.

Webshops use the same In-App Purchasing (IAP) catalog as your game. Changes to products, prices, and promotions are automatically reflected in your webshop. At checkout, the webshop routes the purchase through one of your configured payment providers.

Refer to the following to learn how to structure your webshop catalog and configure payment provider routing for players.
