Introduction
The SIGN ES (Unified API) is currently available in the test environment for initial development and testing, though only a limited set of options can be tested at this stage. Production is not yet activated. For production use, please use the Specialized SIGN ES API.
Spain requires fiscal compliance through TicketBAI, Verifactu, and SII (Suministro Inmediato de Información), depending on the region and the taxpayer’s obligations.
SIGN ES (Unified API) brings Spanish fiscalization into the fiskaly Unified API surface, providing the same developer experience as SIGN AT, SIGN IT, SIGN FR, SIGN PT, and SIGN SE.
SIGN ES remains available as a Specialized API as well and that’s the only version ready for production right now. SIGN ES (Unified API) can only be used for testing at this point.
