On building services based on the Tax Administration’s APIs and systems

The Tax Administration offers several API interfaces that external system suppliers can integrate with to deliver services through users’ systems. An API is a structured way to transmit data from one location to another, from computer to computer.

We’re modernising a number of our services in connection with the modernisation of Altinn. Therefore, there will be a number of different solutions for using our services via an end-user system during a transition period.
