ABC Trainerize Training API

openapi: 3.2.0
info:
  title: ABC Trainerize Client Data Training API
  description: 'Programmatic access to an ABC Trainerize personal-training / fitness-coaching business. The API lets an integrator add, modify, and retrieve client data - clients, training programs and workouts, goals, habits, body stats, nutrition, appointments, messaging, and tags/groups - plus register webhooks for business events (workout completed, new client, goal hit, and more).

    ACCESS MODEL: The API is a partner / private API available only on Studio and Enterprise plans. Credentials (an API key and/or an OAuth2 connection) are provisioned from the Trainerize account settings; ABC Trainerize support does not assist with building API calls and the full reference is behind the authenticated help center.

    GROUNDING NOTE: The live API host and version prefix in `servers` below were confirmed by direct probing (https://api.trainerize.com/v03, Microsoft-IIS / ASP.NET Web API). The individual operation paths and request/response schemas in this document are MODELED from ABC Trainerize''s publicly documented capabilities (the ABC Trainerize help center API/webhooks article and the published Zapier / Latenode / partner action catalog); they are representative and were NOT copied from a public OpenAPI reference, because ABC Trainerize does not publish one openly. Treat exact paths, parameter names, and payloads as illustrative and verify against the gated reference before implementation.'
