SmartHR is a leading Japanese cloud HR, labor, and personnel management SaaS (smarthr.jp). Its per-tenant REST API exposes an organization's employee ("crew") records and the master data around them - departments, employment types, business establishments, and custom field templates - plus webhook subscriptions for change notifications. The API is served from each customer's own tenant subdomain (https://{tenant}.smarthr.jp/api) under a /v1 path, and is authenticated with a per-tenant access token passed as a Bearer token.
