Customizing the Partner Agreement and ION configuration for third-party connectivity tool
If you only need the FBM proprietary output and intend to use an alternative third-party tool to connect to KSeF, you must manually configure the settings in the Partner Admin tool.
For this scenario, the FBM proprietary invoice XML message is supported. Support for the connection to the third-party tool and processing feedback from it is not included. Therefore, the use of inbound mapping is not applicable.
