Validate your first file

Validate your first XML file with the free eConnect Validator: what it checks, how to use it and how to read messages.

Validate XML before you send via the API. The free eConnect Validator runs the same class of checks as the PSB and Peppol network. Automate later with the Validate API.

What it checks
  • XML schema — structure and required elements
  • Schematron rules — business rules for the profile
  • Profile detection — from CustomizationID (Peppol BIS, NLCIUS, PINT, XRechnung, CII, …)
  • Country-specific rules — applied from country codes
How to validate
  1. Take a test file from sample invoices
  2. Open the Validator — no account needed
  3. Upload or paste XML
  4. Read the report (error / warning / info) with codes and XPath

Error prefixes: BR- (EN 16931), PEPPOL- (Peppol-wide), plus country prefixes such as NL-R-.

Pipeline validation

With sandbox credentials, call the Validate API without storing or routing the document. The PSB validates again on send.
