Nmbrs

Nmbrs (Visma Nmbrs) is cloud HR and payroll software for the Netherlands and Sweden, widely used by employers, accountants, and payroll service providers. Nmbrs exposes its HRIS and payroll data through a public API in two generations. The current, forward-looking interface is a REST API served from https://api.nmbrsapp.com, authenticated with OAuth 2.0 (Authorization Code flow via identityservice.nmbrs.com) plus a per-product subscription key, with granular scopes over companies, employees, employments, salaries, wage components, payruns, and absences. The older SOAP API (api.nmbrs.nl/soap/v3 - EmployeeService, CompanyService, DebtorService) remains available for existing integrations but is deprecated and scheduled to be retired on 1 March 2027, after which REST is the only supported API.

Nmbrs publishes 7 APIs on the APIs.io network, including Absences API, Companies API, Employees API, and 4 more. Tagged areas include Human Resources, HRIS, Payroll, Employee Management, and HR.

Nmbrs’ developer surface includes authentication, documentation, API reference, signup flow, engineering blog, and 7 more developer resources.
