The entire suite of products defined for a merchant is called a master catalog, which is shared across sites with individual catalogs. See how to create a new standard product Products can include: * An unlimited number of attributes, which uniquely describe the product * Images of the product to display on the storefront * Variations based on size, color, and other options Products can also belong to one or more categories, which hierarchically classify products. Refer to [Categories](/pages/category-overview) for more information about the different types of categories an using them to classify your products. ## Prerequisites Before you create products in a catalog, you must first complete the following steps: 1. Create [product attributes](/pages/product-attributes-overview) to define the characteristics of your products. 2. Create [product types](/pages/product-types-overview) that provide templates of settings and attributes for a specific set of products. ## APIs and Postman Runner For more information on the APIs associated with products and the product interfaces, see the [Catalog Admin API documentation](/api-overviews/openapi_catalog_admin_overview). You can also use Postman and Postman Runner to update products, product attributes, and sort product type attributes instead of the UI or [import/export tool](/pages/import-export-api-overview).
