Why is the Számlázz.hu PDF not downloading?

The PDF downloads when Számlázz.hu is set as the invoicing provider, the API key is filled in, Download invoice PDFs is on, and the invoice is an outgoing one with an invoice number and no PDF attached yet.

Every hour the system looks for outgoing invoices that have an invoice number but no PDF yet, and downloads the PDF from Számlázz.hu. You can also fetch one invoice by hand: on the invoice page choose Refresh from Számlázz.hu in the More actions menu.

If the PDF does not arrive, check that:

  • under Team Settings → Integrations the Invoicing provider is Számlázz.hu, the API Key is filled in and Download invoice PDFs is on;
  • the invoice is an outgoing (revenue) invoice – Számlázz.hu has no PDF for incoming ones;
  • the invoice number is filled in exactly as it appears in Számlázz.hu;
  • no PDF is attached yet – if one is, it is not downloaded again.

If a download failed, the invoice shows "PDF download failed" and the system does not retry on its own. Fix the cause (for example the invoice number), then start it again with Refresh from Számlázz.hu.
