Klardaten APIs
OpenAPI specifications for the APIs we operate. Both give you access to DATEV without having to run a DATEV installation in your own stack.
Gateway API ↗
REST API that mirrors the DATEVconnect modules. Same data model as DATEVconnect, accessible without running a local DATEV installation.
Enterprise API ↗
Extended DATEV access beyond what DATEVconnect exposes – for partners and software vendors that need fields or operations not covered by the Gateway.
Official DATEVconnect documentation
Official DATEV documentation for the DATEVconnect modules, with all endpoints and fields.
