Payhip
Payhip is an all-in-one e-commerce platform that lets creators sell digital downloads, online courses, memberships, coupons, and physical products directly to their audience, with hosted storefronts and checkout. Its public REST API (base https://payhip.com/api/v2) currently exposes programmatic management of Coupons and verification/management of software License Keys, authenticated with an API key or a per-product secret key. Order, customer, and transaction data is delivered to applications through signed webhooks (paid, refunded, subscription.created, subscription.deleted) rather than through pollable REST resources.
