description: The Cart.com Online Store API (formerly the AmeriCommerce REST API) is a JSON REST API scoped to a single merchant
storefront domain. It exposes 136 paths and 262 operations across catalog (products, variants, categories, attributes,
inventory, pricing), orders (carts, cart items, orders, order items, payments, shipments, quotes, subscriptions), people
(customers, addresses, profiles, users), content (blogs, pages, links), marketing (adcodes, coupons, discounts, gift certificates,
mailing lists), settings (payment methods, shipping providers, tax rates, warehouses, store locations) and system resources.
It is HTTPS-only, uses snake_case JSON, ISO 8601 datetimes, and a shared query syntax for filtering, paging, sorting,
field selection and nested-resource expansion.
