Step-by-Step Integration

⚠️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.

This guide walks you through the complete process of integrating the fiskaly SIGN AT API via the Unified API for Austrian fiscal compliance (RKSV).

Prerequisites

• A fiskaly account with access to the SIGN AT product
• API credentials (API Key and API Secret) from HUB
• FinanzOnline credentials (Teilnehmer-ID, Benutzer-ID, and PIN) for the taxpayer
• Familiarity with the Unified API concepts

Integration Workflow

1. Create an Organization

   Create an Organization on HUB to represent your business entity.

2. Create a Taxpayer

   Register a Taxpayer under your Organization with the required Austrian tax identification details (Steuernummer and UID-Nummer).

3. Provide FinanzOnline Credentials

   Supply the FinanzOnline portal credentials (Teilnehmer-ID, Benutzer-ID, and PIN) for the taxpayer to enable communication with the Austrian tax authority.

4. Create a Location

   Set up a Location representing the physical point of sale.

5. Commission a System

   Create and commission a System (Registrierkasse) at your Location. The System will be registered with FinanzOnline.

6. Start Recording Transactions

   Use the Unified API to create transactions (receipts, invoices) that are signed in compliance with RKSV requirements.
