Appendix: Germany (KassenSichV)

This appendix expands on the General Part's information by adding details specific to the German market. This additional information is provided only where applicable. The remaining chapters, for which there is no further information required, were omitted.

Upgrading to PosSystem API (v2)

New features such as e-invoicing are available exclusively through the PosSystem API (v2). If you are currently using the v0 interface (WCF/REST), see the Migrating from API v0 to PosSystem API (v2) guide for instructions.

Please note that this information is only complete when combined with the General part. To implement the Middleware, users should get themselves familiar with the general information first and then refer to the country-specific details listed here.
