Storefront API now supports product bundles
API
Effective September 27, 2023
It’s now possible for merchants using Hydrogen or the Headless Channel in the admin to offer bundles with Shopify.
Headless merchants can choose from creating fixed bundles and multipacks with our free Shopify Bundles app, using one of these updated bundle apps for more bundle support or using our APIs (Shopify Plus and Shopify partners only) to create a custom bundle offering.
