Get Catalog Items

Developer Preview

This API is subject to change. Bug fixes and new features will be released based on developer feedback throughout the preview period.

Retrieves data for specified items in a specified catalog.

Wix calls this method whenever a cart or checkout is updated, and when an item is added to an order.

The method receives a catalogReferences array. Each catalog reference in the array contains:

  • The ID of the item whose latest information Wix needs to retrieve.
  • The ID of the app providing the catalog containing the item.
  • Optional details about preferences or customization of the item.

The method also receives preferences for the currency and weight unit to be used in the response.

Your external catalog can store and organize item details in any way you prefer. When implementing the Catalog service plugin, learn how to handle item variants in a way that meets your needs.

The method's response must contain a catalogItems array. Each item in the array must contain:

  • A catalogReference object. This must be identical to the catalogReference object received in the request.
  • A data object with full details about the item.

Notes:

  • If an item doesn't exist in the catalog, the response must exclude it from the catalogItems array in the response.
  • When none of the items requested exist in the catalog, catalogItems must contain an empty array.
  • Wix calls the method every time a cart or checkout is updated. If the response doesn't include an item that was already in the cart or checkout, Wix removes the item from the cart or checkout.
