API & development

Can I add an email address to my invoices?

Yes, but only when sending a raw UBL document.

Can I send an XML document directly via the API?

Yes, via the sendDocument endpoint, as long as the XML document is fully Peppol/UBL compliant.

Can I view logs of sent documents?

Yes, via the dashboard and via API responses (status/log fields).

How can I download my sent or received documents?

You can download documents as a complete package (ZIP) or just the XML file via the API or dashboard.

How can I see feedback when a document is rejected by the recipient?

Not always — this depends on the receiving software.

How can I test without sending real invoices?

Use the Recommand Playground to safely test without sending documents over the Peppol network.

How do I add a structured reference (OGM) correctly?

Use the numeric format, without "+++" or "/".

How do I use the Playground environment?

The playground is a separate test environment without real Peppol delivery.

What is the correct format for a Peppol address?

Use the ISO6523 format, e.g. 0208:BE0123456789.

What is the difference between production and playground?

The playground is for testing; production for real documents on the Peppol network.
