  title: Cart Actions Endpoints Item Adjustments API
  description: fabric's **Cart API** lets you add, update, and remove items from your Storefront cart, either as a guest user or as a logged-in user. It also provides functionality to merge carts when you switch from guest user to logged-in user, and apply coupons and other attributes (for example, gift wrapping) to the line items. Additionally, the API supports more advanced tasks such as using multiple carts within a B2B organization, sharing carts, and supporting a unified cart experience for multi-region and multi-brand businesses.<p>The Cart API provides high performance, scalability, multi-tenancy, and configurability to the end-to-end order processing actions that start from the item being added to the cart; through the pre-checkout stage that includes billing, shipping, and payment details; to the checkout stage where the order is processed and confirmed by fabric's Order Management System (OMS)
