As part of the opening of our digital DATEV ecosystem, we will enable any software company to connect to our online APIs (DATEV Datenservices). In the future, it will also be possible to implement the online APIs without a partnership with DATEV. All further information (registration, procedure, etc.) for implementing the online APIs can be found here: How to integrate a DATEV Datenservice
All software companies that have already integrated an online API through our legacy API infrastructure must migrate their integration to the new API gateway by 31 March 2024. You can find out more about the migration here.
By the way: With our new newsletter "Developer Portal - Newsletter for Software Developers" you can also be actively informed about new information around the DATEV interfaces. You can subscribe via the following link: DATEV eG - Subscribe to newsletter
