API & development
Frequently asked questions about 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 send document 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.
Must I register recipients in my team first to be able to send?
In production no, in playground yes.
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.
