Through the VTJkysely interface, a public or private organisation can retrieve real-time data from the Population Information System directly into its own information system.
The VTJkysely interface is suitable for an organisation that wants to e.g.
- check basic customer information
- offer their clients electronic services
- verify data during application processing.
The Population Information System data disclosed to the organisation and their purpose of use are always agreed on a case-by-case basis with the Digital and Population Data Services Agency.
The VTJkysely interface is not intended for regular or extensive updating of data in one's own register or for other mass surveys. For these purposes, the Digital and Population Data Services Agency's update services for customer registers of public administration and private companies and organisations are suitable.
Data in the VTJkysely interface is retrieved and received as XML messages. For more information on the technical implementation of the interface, see the page Technical implementation of the VTJkysely interface and using the service.
If you want an alternative to a direct VTJkysely interface, you can also contact companies granted the right to relay information retrieved through the VTJkysely query interface and ask them about services based on VTJ information. View the list of these companies: In this case, the permit processing may be lighter and faster.
Local and central government authorities as well as welfare authorities can use the VTJkysely interface free of charge.
- For other public sector customers and private sector customers performing statutory tasks, the use of the VTJkysely interface is invoiced on the basis of the number of surveys conducted on a monthly basis.
- In addition, public sector customers are charged an establishment fee for the VTJkysely interface.
- Businesses and private organisations are charged a fee for the queries made in the VTJkysely interface. The cost of each query depends, among other things, on the scope of the content of the data. The cost of setting up the connection is also charged from the customer organisation.
