  x-method: generated
  x-source: https://docs.vitally.io/en/articles/9880649-rest-api-overview and the per-resource REST API reference articles (accounts, users, tasks, organizations, notes, conversations, npsResponses, admins, customObjects). Operations, hosts, authentication, pagination and error semantics are taken verbatim from Vitally's published documentation; object schemas for Account, User and Task are transcribed from their documented object tables. Not a provider-published OpenAPI — a faithful generation from the public docs.
  description: Vitally's public REST API for creating, updating, retrieving and listing the core Customer Success objects — Accounts, Organizations, Users, Tasks, Notes, Conversations and NPS Responses. Authentication is HTTP Basic using a Vitally REST API key as the username. List endpoints use cursor-based pagination ordered by updatedAt (default) or createdAt.
