Introduction

This guide provides an overview of the fiskaly DSFinV‑K API.

What is the DSFinV‑K?

The DSFinV‑K (Digitale Schnittstelle der Finanzverwaltung für Kassensysteme - Digital Interface to the Revenue Administration for Point-of-Sale Systems) defines specific rules regarding the data to be included in Cash Point Closings and the export format. The fiskaly DSFinV‑K API is a RESTful API that takes a Cash Point Closing and stores data to be later exported according to the DSFinV‑K.

Background

All data recorded by electronic record-keeping systems (ERS), for example a PoS system, must be secured with a certified technical security system (TSS) and made available through a standardized digital interface during audits. The first requirement is met by integrating the fiskaly SIGN DE API. The DSFinV‑K API corresponds to the second requirement.

The naming convention in our API is based on the DFKA Taxonomy.

Additional Ressources

It is very helpful to get familiar with the DSFinV‑K documentation provided on the Bundeszentralamt für Steuern (BZSt) - the German Federal Central Tax Office's official site. These documents are available in both English and German, though it is worth noting that certain sections may only be provided in the German version.

In addition, the Federal Ministry of Finance has an FAQ page dedicated to the legal requirements for PoS vendors in Germany.
