  title: freee API (Accounting and HR/Payroll) Account Items Partners API
  description: 'A representative, hand-authored subset of the public freee REST APIs for the freee Accounting product (会計freee) and the freee HR & Payroll product (人事労務freee). freee is a Japanese cloud accounting, invoicing, and HR / payroll SaaS. Accounting endpoints live under https://api.freee.co.jp/api/1 and HR / payroll endpoints under https://api.freee.co.jp/hr/api/v1. All requests are authenticated with an OAuth 2.0 (authorization code) access token sent as `Authorization: Bearer <access_token>`. Most reads and writes are scoped to a freee company via the `company_id` parameter. This document is grounded in freee''s own OpenAPI schemas (github.com/freee/freee-api-schema) but is a curated subset - it does not reproduce every operation, field, or response of the freee platform. See the official reference for the complete surface.'
