REST API for the Bakuraku (バクラク) back-office suite. Publicly documented capabilities are retrieval and list-search of applications/requests (申請), download of attached files, creation of applications for the purchase-request, payment-request and general-purpose application types, and read access to the tenant user, group and position directory. Bakuraku 請求書発行 additionally exposes document upload (CSV/PDF) and recipient-master create/update. Authentication is a scoped API key issued from the Bakuraku admin console (API管理). Access requires an existing Bakuraku contract plus a separate API application; the reference at https://api.bakuraku.layerx.jp/rest/docs/ answers HTTP 401 with WWW-Authenticate: Basic to anonymous callers and no OpenAPI is published.
