# Mengenmeldungs-Datei herunterladen

> Download the report artifact as an attachment: for `lucid_de` the LUCID Datenmeldung XML (`application/xml`), for the worksheet registers the JSON transcription worksheet (`application/json`). The file is re-derived from the report's frozen snapshot after re-verifying its SHA-256, so a downloaded report is byte-identical to what was generated, every time. Requires `packaging:read`; customer workspace with the PPWR module enabled — see the guide.
