  description: 'Medusa Store API - the public REST surface consumed by storefronts and

    end-customer clients of a Medusa commerce application. Provides carts,

    products, collections, categories, regions, customers, orders, payments,

    shipping, returns, and gift cards. Requests are scoped by sales channel

    using a publishable API key passed in the x-publishable-api-key header.

    Customer-scoped requests use a JWT bearer token or a cookie session.
