Product Library API overview
The product library service defines product items and make them available for merchants for selling in Zettle. The Product Library API lets developers programmatically work with product items in a merchant’s product library.

Explore the sections in the following to get an overview of the different parts of the Product Library API.
What is a product library? A product library holds items like products, product variants, and discounts. Products and their variants can have associated properties like name, descriptions, size, colour, and price. This makes up the product data model. For more information, see Product library concept.
Using the Product Library API you can create, retrieve, update, and delete products and their variants.
Images in the product library are managed through the Zettle Image service. You can then retrieve images and associate them with products in the product library.
Product categories are used for organizing items in the product library. Merchants can create categories from the user interface.
