  title: Virtuagym Public API (v1) Billing Coaching API
  description: 'The Virtuagym Public API lets fitness businesses, health clubs, and partner integrations read and write club data programmatically - members, staff (employees), membership definitions and instances, member credits, invoices, visits (check-ins), events (classes) and their participants, and coaching workout assignments. This document models the current v1 club-scoped surface.

    Access model: Virtuagym''s authoritative reference documentation is access-gated - you request access by emailing api@virtuagym.com with your GitHub username, and you provision an API key and Club secret in the Virtuagym portal under System settings > Business info > Advanced. The endpoints, methods, and query parameters below are grounded in Virtuagym''s publicly mirrored API wiki and in live host probes; request/response bodies are modeled honestly and marked with additionalProperties where the full field set is not published. Treat schema shapes as a starting point and reconcile against the official reference once access is granted.

    Authentication: v1 endpoints authenticate with an `api_key` and a `club_secret`, both passed as query-string parameters, over HTTPS only. (Legacy v0 endpoints used HTTP Basic Auth and are deprecated; a separate OAuth 2.0 flow exists for end-user-context calls and is out of scope for the club-scoped v1 surface modeled here.)'
