Changes in Fortnox API Endpoint
From 9th of February all requests towards apps.fortnox.se/3 will be redirected to api.fortnox.se/3
The Fortnox API must always be accessed via the address api.fortnox.se/3 . For technical reasons, it has previously been possible to use the address apps.fortnox.se/3 .
This option will be discontinued starting February 9, 2026.
From that date forward, any API calls directed at apps.fortnox.se/3 will be automatically redirected to api.fortnox.se/3 , and will be subject to the standard limitations of that endpoint.
