Catalog - Product modifiers

The Catalog API manages products, categories, brands, bulk pricing rules, and more. To learn more about catalog resources, see the Catalog Overview.

Product modifiers represent choices that the shopper can make to change how the merchant customizes or adds on to the product. Examples include shipping insurance, monograms, custom inseam length, and color selections for unfinished products.

Modifier values do not change which item is picked in a warehouse, but they change what happens to that item between the warehouse shelf and the shopper taking possession of their order.

Critically, modifier values do not change which product variant is fulfilled. You cannot track inventory for combinations of modifier values.

You can add an adjuster to a modifier value to override the underlying product variant's properties, such as price, weight, and shipping rules. Not all modifier types are compatible with adjusters.
