New technical documents available


On 6 February 2023, the project to establish a positive credit register published new documents related to the reporting of loan data:

  • Changes to loan contract information – API description
  • Checking loan data – API description
  • API processing rules and error codes
  • New message examples

We will not publish a separate description of the API for making changes to loan contract information. Instead, we have added the text to the description of the API for reporting loan contract information published in December 2022. We have also updated the description of the API for reporting loan contract information and sent a list of the changes to stakeholders by email.

The documents are available in Finnish, Swedish and English.

If you have any questions or comments on the published documentation, please send email to luottotietorekisteri (a) Questions and answers will be discussed in stakeholder events in Finnish on 21 February at 2.30–4 pm and in English on 2 March at 2–3.30 pm.

As work on the register progresses, the published documents may still change. For example, when the stakeholder testing begins in May 2023, things that need to be changed may be detected. If changes affecting the technical implementation are made to the API description or the instructions, updated versions of the documents will be published on the Positive credit register's website. The stakeholders will be notified of the changes by email. The notifications will be sent to the stakeholder mailing list. To join, please send an email message to luottotietorekisteri (a)
