Gumroad is a digital commerce platform that lets creators sell e-books, courses, software, memberships, music, and physical goods directly to their audience without needing a storefront, with built-in checkout, licensing, affiliate management, and analytics. The Gumroad v2 REST API provides programmatic access to products, sales, subscribers, offer codes, license keys, customers, and the authenticated user account. Authentication uses OAuth 2.0 access tokens passed in the Authorization header.
