info:
  title: Twenty Core companies Fields API
  description: 'The Twenty Core API provides REST endpoints for CRUD operations on all CRM records including companies, people, opportunities, notes, tasks, and any custom objects defined in a workspace. All list endpoints use cursor-based pagination. Authentication is via Bearer token generated from workspace Settings → Playground. The API schema is per-tenant and adapts automatically as custom objects are added.

    Note: The full workspace-specific schema is available at https://api.twenty.com/open-api/core (requires Bearer token) and reflects all standard and custom objects configured in your workspace.
