Momence

Momence is an all-in-one management platform for fitness, wellness, and experience-based businesses - studios, gyms, spas, and instructors - covering class and appointment scheduling, memberships and packages, point-of-sale and payments, marketing, and a branded member app. Momence exposes a documented public REST API (api.momence.com, /api/v2) split into a Host API for staff and back-office automation and a Member API scoped to the logged-in customer. The API is authenticated with OAuth2 (authorization code for customers, password grant for staff automation) using public API clients created in the Momence dashboard, and covers members, sessions and bookings, memberships, checkout and sales, reports, appointments, addresses, and saved payment methods.

Momence publishes 8 APIs on the APIs.io network, including auth API, host API, host-checkout API, and 5 more. Tagged areas include Fitness, Wellness, Studio Management, Booking, and Scheduling.

Momence’s developer surface includes authentication, documentation, and 8 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/. This rating is computed from github.com/api-evangelist/momence: open an issue to ask a question, or submit a pull request to add artifacts. Want it done for you? Prioritized profiling — $2,500 →
