Create an e-invoice

create_einvoice

Read-only

Create a valid e-invoice from structured data: XRechnung 3.0 (UBL or CII), ZUGFeRD / Factur-X PDF (EN 16931) or Peppol BIS Billing 3.0. The file is checked with the official KoSIT validator before it is returned; if it fails, you get the rule errors instead of a file. XML comes back as text in xml, the ZUGFeRD PDF as base64 in pdf_base64. XRechnung needs a seller contact (contact, phone, email), a buyer email or Peppol ID (electronic address), a buyer_reference (Leitweg-ID for German authorities) and payment details (iban). Peppol needs peppol_id for seller and buyer.
