How it fits your pipeline

  1. POST the XML

    POST /v1/validate with the raw invoice — Peppol BIS 3.0 or e-SLOG 2.0 is detected automatically, or pinned with ?format=.

  2. Read the verdict

    Each finding carries a rule ID, severity, a human-readable message and a docsUrl into the rule catalogue at /rules.

  3. Gate the send

    Block dispatch or fail CI on valid: false. Rulesets track every May and November release, so the gate never drifts from the law.
