Introduction

⚠️Integration Ready

SIGN AT (Unified API) is currently in integration-ready status. The API is available for development and testing on the test environment, but is not yet activated for production use. For production use, please use the Specialized SIGN AT API.

Austria requires fiscal compliance through the Registrierkassensicherheitsverordnung (RKSV), which mandates tamper-proof recording and signing of cash register transactions. Businesses must register their cash registers with FinanzOnline, the Austrian tax authority’s online portal.

SIGN AT (Unified API) brings Austrian fiscalization into the fiskaly Unified API surface, providing the same developer experience as SIGN IT, SIGN FR, SIGN PT, and SIGN SE.
