This information is intended for developers and owners of services using BankID. This message is a reminder of changes you have to make. To make integration with the BankID service easier, we have replaced the SOAP/XML interface with a JSON based interface. You need to change your services to use the JSON Interface before 29 February 2020. The old SOAP interface will not work after February 2020.

The following summarizes the changes:

  • JSON replaces SOAP/XML
  • The end user IP address is mandatory
  • A cancellation method is introduced
