  title: Attio REST 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.
