  title: RecVue Authentication API
  description: 'RecVue is an enterprise revenue management platform (RevOS) covering order-to-cash, billing, usage-based monetization, pricing, and ASC 606 / IFRS 15 revenue recognition. This OpenAPI is derived from RecVue''s public developer reference at https://developer.recvue.com. The base URLs, the OAuth2 client-credentials authentication, and the paths for representative operations (for example GET /orders) are confirmed from that public reference; the full request/response schemas are honestly modeled from the documented resource operations rather than reproduced field-for-field, and RecVue tenants (production and sandbox) are provisioned through an enterprise sales process. Endpoints marked with `x-endpointsModeled: true` reflect documented operations whose exact path or payload was not verified verbatim. Treat this as a navigational model, not a generated client contract; consult developer.recvue.com/reference for authoritative detail.'
