A product is an item’s listing on the cart platform. It contains information about the product, such as its name and sku. Every variant and parent product are listed in this endpoint. A variant will contain information like the price and inventory levels reflected by the platform. It will also have its parent product’s ID. Parent products are indicated by having their parent_product_id set to the same value as their id. They may or may not have information about their price or inventory levels, but the source of truth for this information will be in their associated variants.
