How this service works
Generate a Factur-X invoice (PDF/A-3 + embedded EN 16931 CII XML) from structured data: send { invoice, profile }, get the PDF bytes (or JSON with base64 + conformity report via Accept: application/json). Targets EN 16931 and the French PA « Flux 2 » rules (payment mentions, business process, electronic addresses) ahead of the 2026-09 mandate. Technical artifact, not tax/legal advice; you remain responsible for data accuracy and PA transmission.
Output
Returns PDF/A-3 binary bytes of the Factur-X invoice, or if Accept: application/json is set, a JSON object containing a base64-encoded PDF string and a conformity report detailing compliance with the selected profile (MINIMUM, BASIC_WL, BASIC, or EN16931) and French PA Flux 2 rules.
