  title: QuickBooks Online Accounting API
  description: >-
    The QuickBooks Online Accounting API is a RESTful API that provides
    programmatic access to QuickBooks Online company data. This specification
    covers core entities including invoices, customers, items, and payments,
    enabling developers to automate accounting workflows, synchronize financial
    data, and extend QuickBooks Online functionality for small and mid-sized
    businesses. All API calls require OAuth 2.0 authorization and a valid
    company ID (realmId). Responses follow the Intuit entity response envelope
    pattern, and the API supports minor version parameters to access newer
    fields and behaviors without breaking existing integrations.
