  title: Attio REST Attributes Lists API
  description: 'The Attio REST API exposes the Attio CRM''s object/attribute/record data model over HTTPS. Attio is an AI-native CRM built on flexible objects (people, companies, deals, users, workspaces, and custom objects), typed attributes, records, and lists. This specification covers the core data-model, activity, collaboration, and platform endpoints: objects, records, attributes, lists, list entries, notes, tasks, comments, threads, webhooks, workspace members, and token identification. All requests are authenticated with a Bearer access token (API key or OAuth) and scoped by granular permissions. Endpoints marked modeled in the repository review were derived from Attio''s published endpoint reference and follow Attio''s documented /v2 path conventions.'
