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 3 API contracts indexed on the APIs.io network, including Coupons API, License Keys API, and 1 more. Tagged areas include E-Commerce, Digital Products, Membership, Creators, and Coupons.

The Payhip catalog on APIs.io includes 1 Spectral governance ruleset.

Payhip’s developer surface includes engineering blog, authentication, documentation, API reference, and 9 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.

Create-or-Update Ergonomics applies to this provider. This API accepts writes, so it carries 10 points of the composite. It is scored from the published contracts themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in front of it, and the first time that check is skipped a duplicate record is created. Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet, not penalised by it.

The six quality facets above are damped to 75 points between them, because the conditional facet above carries the other 25. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 75% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.
