SamCart

SamCart is a checkout and e-commerce platform for selling digital products, courses, memberships, and physical goods directly to customers, built around a high-converting CheckoutOS checkout, one-click upsells, subscriptions, and a courses/members area. The SamCart Public API (v1) is a REST API at https://api.samcart.com/v1 that gives programmatic read access to a marketplace's orders, products, customers, subscriptions, charges, and refunds, plus write actions to cancel or schedule cancellation of subscriptions, refund charges, and update order custom fields. Authentication is via an sc-api API key header, and API access is provisioned by the SamCart Support team rather than fully self-serve.

SamCart publishes 6 APIs on the APIs.io network, including Charges API, Customers API, Orders API, and 3 more. Tagged areas include E-commerce, Checkout, Payments, Subscriptions, and Digital Products.

SamCart’s developer surface includes authentication, documentation, engineering blog, and 7 more developer resources.
