Data Exchange Layer Data Exchange Layer offers a standardised way for transferring information between organisations, enabling the building of safe service entities for citizens, businesses and authorities.

Benefits for the user

The service entity users can receive just the right information from different registers and systems via the Data Exchange Layer. In addition to the quality of services, transparency, data security and privacy protection are also improved.


Benefits for Service Providers Data Exchange Layer is a standardised, cohesive, collaborative, interoperable and secure data exchange layer that gives service providers a completely new kind of opportunity of making themselves visible in services directed at citizens, businesses and civil servants.  Creating entities that combine many different services and data sources is easy and cost efficient.

  • Improves the quality of existing services and products
  • Enables new types of service innovations
  • Savings in infrastructure, archiving and other costs
  • Standardised data security and privacy protection
  • Easy implementation, data access via interfaces – after connecting all included services are available

Software providers can add the functionality of using the Service Data Exchange Layer integrations in their software and systems that enable them to further improve their products.

How does the service work?

The service provider connects its own service with the Data Exchange Layer according to instructions and makes the required configurations in order to make use of the data.

After the connection has been made the service provider can use all the integrated Data Exchange Layer data sources and service components in developing its own service.

As part of the Data Exchange Layer, the API Catalogue brings all the interface content and other information included in the entity available to all.



Needs for change and costs

The service provider must implement the connections between its own services and the Data Exchange Layer. The service interfaces may require changes to ensure compatibility. The service provider must have access to a so-called connection server through which the connection is executed – if necessary, this server may be constructed during implementation.

The service provider may just decide to use the connection catalogue maintained by the Data Exchange Layer to determine the connection information of available services and to develop its services.

The use of the Data Exchange Layer is free for organisations.
