eDelivery Diagnostic Tool

Resolve delivery failures at the source

See exactly where trust or endpoint resolution breaks — across SML/SMK, SMP, and AP.

For Peppol integrators, SMP/AP operators, and eInvoicing platforms that need to find delivery failures, verify trust chains, and debug endpoint resolution fast.

Identify why document delivery fails (SML/SMK, SMP/AP)
Verify trust: signatures and certificate chains
Retain artifacts for history, comparison, and audits
Export full discovery trace + diagram (SVG/PlantUML/MD)
Interactive discovery diagrams with clickable links

Open-source CLI available on GitHub

Node42 diagnostic results are informational and should be used alongside other inputs when making trust decisions.
