Improved document validation

We’ve added first‑class document validation to help you catch Peppol compliance issues before sending documents.

What changed

• New validation service: All transmitted documents are now validated via our dedicated validation service, using EN16931 and Peppol BIS 3.0 rules.
• Stored validation results: Validation output is stored alongside each transmitted document so you can review issues later.
• Outgoing validation enforcement: Companies now have a new setting isOutgoingDocumentValidationEnforced that, when enabled, blocks sending documents that fail validation with clear error messages.
• Incoming documents: Incoming documents are also validated and their results are stored on the transmitted document record.

How validation works

• Automatic XML validation: When you send or receive a document, its XML is passed to our validation service.
• Result handling:
  • If validation succeeds, the document continues to be processed and sent as before.
  • If validation fails or an error occurs and enforcement is enabled for the company, the API returns a 400 response with a structured list of rule codes and human‑readable error messages grouped by field.
• Per‑company control:
  • New companies have validation enforcement enabled by default via isOutgoingDocumentValidationEnforced.
  • Existing companies can enable or disable this behaviour in the company settings UI.

Dashboard improvements

• Transmitted document details:
  • A new “Document Validation Issues” panel surfaces validation results whenever a document is not marked as valid.
  • You can inspect the full validation payload, parsed JSON structure, and original XML for each transmission.
• Document list indicators:
  • The transmitted documents table now shows a visual indicator next to the document type when validation issues are present.
  • Hovering the indicator opens a popover with the most important validation errors for quick inspection.

These improvements make it easier to keep your Peppol traffic compliant and to diagnose issues quickly when something goes wrong.
