# Catalogs *Product catalogs* are data feeds that hold a list of your products and their metadata, like an image of them or their current price. Product catalogs are commonly created via an e-commerce or shopping cart solution, which are then imported to impact.com. While you cannot create, update, or delete a product catalog via API, you can create, update, or delete items within a product catalog via API. Product catalogs are used to show your partners what products you sell and supply them with information on those products. See the [Product Catalogs](https://app.impact.com/secure/advertiser/engage/ads/productcatalogs/manage-ads-product-catalog-flow.ihtml) screen to manage product catalogs, as well as the items within them, via the impact.com web app. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
