Online APIs

Our Online APIs offer bidirectional data exchange directly via the DATEV data center. This allows to be connected with DATEV online and desktop apps. We have implemented the web standards OAuth 2.0 & OpenID connect and OAuth 2.0 Code Flow mit PkCE .NET for authentication and authorization with the DATEV data center. This form of interface offers the user a very high level of comfort. The data exchange between the apps can not only be automated, it can also be autarkic after a separate approval by the user. This makes it ideal for data exchange between companies and tax consultants.
