Wix enables site owners to quickly and easily create and manage an online store for physical and/or digital products on their site. Read more about the Wix Stores features.
Wix is introducing Catalog V3, a new set of APIs for the Wix Stores product catalog, set to roll out in Q2 2025. This upgraded catalog will empower Wix Store owners with enhanced tools to build more comprehensive product catalogs and streamline store management. Key improvements include more detailed management of product variants, advanced inventory capabilities, expanded customization options, and more.
Therefore, each site supports either Catalog V1 or Catalog V3, but not both at the same time. Use the Catalog Versioning API to determine the API version required for a given site. Note that if you use the wrong version of the API, your calls will fail.
