Introduction to RKSV.Sign

In Austria, fiskaltrust offers a cloud-based signing-only product called RKSV.Sign for customers that prefer to not use the Middleware, e.g. because they've already made RKSV-compliant (Registrierkassenverordnung) implementations themselves.

In this section, we've described the API calls to use for signing receipts and obtaining additional information from the signing service. Additionally, we've prepared a Postman collection, showing the most common task


Before starting, users need to generate a CashBox via our API (which is used for authentication). For more information, see the RKSV.Sign section in our documentation for PosDealers. For easier reference, we've included a sample of the respective API call in the Postman collection mentioned above.
