How to integrate a DATEV dataservice

Access to our online API sandboxes is available immediately upon registration in the Developer Portal. This allows for an initial validation of the intended Use Cases to get started.

A technical check by DATEV is required before end users can use the API integration. The mandatory onboarding package can be ordered directly during the appointment booking process. More information about the Onboarding Package is available during the booking process. See also the FAQs.

We also recommend the booking of an initial consultation. This will ensure that the selected online APIs are suitable for the intended purpose. This consultation is also part of the mandatory onboarding package.

Below you will find all relevant information for the API integration.
