Cart Transform API (Product Bundles) — Developer Preview


The Cart Transform API is now available in a developer preview. You can use this new Shopify Functions API to create unique product bundle offerings that display directly in the checkout.

There are two key parts building a product bundle. First, you can determine which specific products can be merged into a bundle. Second, the Cart Transform API can also expand a bundle product into its individual components, making it easier to complete tasks on the backend—like calculating taxes, shipping weights, decrement inventory, and more.
