API-Dokumentation

Ein Endpunkt genügt: POST /v1/convert (multipart/form-data). Rein: Rechnungsdaten (JSON oder CII-XML) und optional ein PDF. Raus: ein validiertes ZUGFeRD-/Factur-X-PDF/A-3 samt Prüfbericht.

Authentifizierung. API-Token als Authorization: Bearer eun_live_…. Ohne gültigen Token läuft der Request anonym — das Ergebnis trägt dann ein Wasserzeichen. Tokens erstellen Sie im Dashboard.

Maschinenlesbare Spezifikation: /openapi.json (OpenAPI 3, z. B. im Swagger-Editor prüfbar).
