Can AI agents automate Fortnox?

Fortnox is automatable through its public REST API. The documented resource catalog covers invoices, customers, suppliers, orders, vouchers, accounts, articles, contracts, warehouse documents, and salary objects with create, read, update, and delete operations. Authentication uses a modified OAuth 2 authorization-code flow with one-hour access tokens and 45-day refresh tokens, plus a client-credentials grant for service accounts after tenant consent. Integrators must hold a Fortnox developer license, and each scope requires the customer company to license that product module. Rate limits are 25 requests per 5 seconds, or 300 per minute, per access token and tenant. Fortnox documents a Kafka-backed websocket stream for invoice and customer topics and HMAC-signed webhooks for company-order and consent events. Make publishes a Fortnox connector with invoice, customer, supplier, and payroll modules. Zapier, n8n, and Microsoft Power Automate had no Fortnox connector in their public catalogs on 2026-08-21. Community MCP servers appear in the official MCP registry; Fortnox's own developer documentation does not establish a first-party server, so MCP ownership remains unknown. Computer-use viability is unassessed. Separately branded Fortnox financing products are outside this record.
