• Check invoice slice

  check_invoice

  Read a UBL Invoice XML slice of at most 60000 characters. Returns the business terms that slice writes, the field-map gaps, and one stored note when BR-DE-15 finds no non-empty buyer reference (BT-10). evaluation is false: no Schematron runs. The result does not say the invoice passed. The XML is not stored. A larger file is the raw body of POST /v1/invoices/check, up to 1048576 bytes.
