  title: Nmbrs Public REST API (HR & Payroll) Absences Wage Components API
  description: 'Modeled OpenAPI for the Visma Nmbrs public REST API - the current, forward-looking interface to Nmbrs HR and payroll software (Netherlands and Sweden). The REST API is served from https://api.nmbrsapp.com and is authenticated with the OAuth 2.0 Authorization Code flow (identityservice.nmbrs.com) plus a per-product subscription key sent on every request. It exposes HRIS and payroll resources - companies, employees, employments, personal and salary info, wage components, payruns, and absences - scoped by granular OAuth scopes such as employee.info, employee.employment, and employee.payment.

    HONESTY NOTE: The Nmbrs REST API reference is published as an interactive Stoplight project rather than a downloadable OpenAPI file, and the live endpoints are gated behind OAuth + a subscription key (GET https://api.nmbrsapp.com/api/companies returns 401 unauthenticated). The paths, parameters, and schemas below are MODELED from the published resource groups and the confirmed base URL / auth model; they are a faithful representation for discovery, not a byte-for-byte copy of the vendor spec. Nmbrs also operates a separate, older SOAP API (api.nmbrs.nl/soap/v3, EmployeeService / CompanyService / DebtorService) that is deprecated and scheduled to be retired on 1 March 2027 - it is described in the repository README and review, not in this REST document.'
