Factur-X generator API for France and hybrid EN 16931

Hybrid PDF/A-3 with embedded CII, built on official FNFE artifacts. All five profiles detected and validated. Bring your own PDF or use the EInvoiceFile template.

Factur-X is France’s hybrid e-invoice: PDF/A-3 plus embedded CII, in profiles from MINIMUM to EXTENDED. It is the format French B2B reform discussions centre on, alongside Chorus Pro for the public sector.

EInvoiceFile creates Factur-X from JSON and validates the embedded XML. It does not file the invoice with Chorus Pro or a French PDP. Your application, or your partner platform, does that transmission.
