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.

Payhip publishes 2 APIs on the APIs.io network: Coupons API and License Keys API. Tagged areas include E-Commerce, Digital Products, Memberships, Creators, and Coupons.

Payhip’s developer surface includes authentication, documentation, API reference, and 7 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Payments regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/.
