Service description

With the Suomi.fi e-Authorizations interface services, you can reliably check that the user has the right to act on behalf of another person or organisation in your service.

The right to act on behalf of another party is based on the information kept in basic registers or a specific mandate:

  • We recommend that you enable acting on behalf of another party on the basis of the role found in a basic register. In that case, such parties as guardians of a child, entrepreneurs and board chairpersons have direct and easy access to your service and do not need a specific mandate.
  • Register data is not always enough and in such cases, acting on behalf of another party is also enabled with a mandate. In that case, your customers first grant the mandate in Suomi.fi and after that, the assignee can use the service.

The Suomi.fi e-Authorizations service is intended for both public administration and private sector organisations. With our service, your mandate information is always up to date, which makes acting on behalf of a person or an organisation easier and provides your customers with a smooth service experience. 

The Suomi.fi e-Authorizations retrieve the information from basic registers and the authorisation register, and return a real-time response to the service on the right to act on behalf of another party.

It is easy to grant and invalidate mandates in Suomi.fi e-Authorizations online. Persons and organisations that cannot use the service independently can grant and invalidate mandates with an application. Read more about authorisation with applicationOpens in a new window..

The use of Suomi.fi e-Authorizations is subject to a fee for organisations that are not part of public administration nor a company owned by a public sector entity. Read more: Liability to charge and pricing.
