Update Cart Attributes
Shopify Storefront data and cart logic is bound to your Webflow elements through Shopyflow attributes. Connecting your Webflow site to Shopify is done by adding custom attributes to your Webflow elements.
Yet, you are not required to type or edit attributes manually. Shopyflow provides you with the pre-configured components needed to create your store, as copyable Webflow elements right in Webflow designer.
All the copyable Shopyflow Components are native editable Webflow elements. There is no layout or styling limitation on any element.

Cart Attributes are custom key-value pairs that attach additional information to the shopping cart, persisting through checkout and appearing in order details. You can use them in common scenarios like gift options, delivery instructions or custom fulfillment workflows. Once set, these attributes are accessible in Shopify admin, order notifications, Shopify Flow automations, and third-party fulfillment apps.
