> 💡 **Why this matters:** Synchronized Cdiscount categories are necessary because they are used to build and configure your product [Models](https://doc.common-services.com/en/article/marketplaces-cdiscount-configuration-categories-cdiscount-flux-prestashop-1i5uct9/#3-what-is-a-model). If a category is missing or outdated in your system, you won't be able to map your products to it properly.
