SmartHR Webhooks API

  title: SmartHR Business Establishments Webhooks API
  description: 'The SmartHR API is a per-tenant REST API for the SmartHR cloud HR / labor and personnel management platform (smarthr.jp). It exposes an organization''s employee ("crew") records and the master data around them - departments, employment types, custom field templates, business establishments - plus webhook subscriptions for change notifications. The API is served from each customer''s own tenant subdomain (https://{tenant}.smarthr.jp/api) and all resources live under the /v1 path. Authentication is a per-tenant access token passed as a Bearer token (or via HTTP Basic with the token as the username).

    This document models a representative, grounded subset of the API. The endpoints below are confirmed against SmartHR''s published API reference and the community Go SDK (github.com/ktsujichan/smarthr-sdk-go). SmartHR''s full API reference documents additional resources (dependents, bank accounts, payrolls, positions, job titles, tags, companies, and more) that are not modeled here.'
