What is a Fortnox integration?
A Fortnox integration connects Fortnox with another system so that data flows automatically between them. Instead of manually exporting and importing orders, invoices, products, and customers, the integration keeps both systems in sync.
Fortnox has an open API that enables integrations, and there are three ways to connect:
Fortnox Marketplace — Fortnox's own marketplace where certified partners offer ready-made connectors. Junipeer is listed here.
Integration platform (iPaaS) — a cloud service like Junipeer where you configure which data flows, how it maps, and get error handling and monitoring included. Read more about integration platforms →
Custom-built integration — you or a developer builds directly against the Fortnox API. Gives full control but requires maintenance.
