What is Maskinporten?

Maskinporten and Altinn are national common components developed and operated by the Norwegian Digitalisation Agency (Digitaliseringsdirektoratet - Digdir). Together, they aim to facilitate the sharing and utilization of data across systems. These solutions ensure the verification of the identity of businesses and provide them with the appropriate access to data offered by public entities through interfaces. A prerequisite for using Maskinporten and Altinn is that the organization is registered in the Norwegian Business Registry (Enhetsregisteret) with a Norwegian organization number.

Maskinporten is a solution provided by the Norwegian Digitalisation Agency (Digdir) for access management for businesses that exchange data. The solution ensures identity assurance between organizations and provides authentication for machine-to-machine communication. It enables the integration of systems and the development of new services in an efficient manner.

In the future: Altinn (authorization) will allow for the delegation of rights to other organizations or individuals. This delegation is based on registered roles in the Norwegian Business Registry (Enhetsregisteret). This is not yet implemented.

Maskinporten ensures secure authentication and access control for data exchange between businesses. The solution guarantees the identity between organizations and enables the integration of systems and development of new services in an efficient manner.

Operations and monitoring

Maskinporten aims to maintain an uptime of 99.9% and, in case of any deviations, it rarely experiences downtime exceeding 5 minutes. Therefore, we recommend that our clients implement a retry mechanism to try again if messages are rejected without clear error messages.

We further recommend monitoring both planned and unplanned operational disruptions:

5. Client integration

API consumers must develop their own application/system that retrieves access tokens from Maskinporten and exchanges them for access tokens signed by Norwegian Customs.

Access tokens signed by Norwegian Customs can be used throughout its lifetime, so it is recommended to cache them when communicating with the APIs. For a smoother experience, it is further recommended to exchange it for a new token before (e.g., 1 minute before) the expiration of the previous one.

5.1 Get access token from Maskinporten

See Maskinportens own documentation on how to get an access token.

Digdir has published a repository on github (jwt-grant-generator) which demonstrates how to get an access token from Digdir's services, for example from Maskinporten.
