Cryptographically bind EU Digital Identity to every B2B invoice. Zero-knowledge proof infrastructure for the Peppol network.
Standard invoices are unsecured documents. They can be intercepted, edited, and forged without a trace.
From invoice submission to cryptographic proof — the entire flow completes in under 3 seconds.
Your system sends a SHA-256 hash of the invoice. Validor never sees the raw document — only the fingerprint. True zero-knowledge architecture.
A QR code triggers an OpenID4VP request. The sender proves their identity with their EUDI Wallet, sharing only the minimum required claims.
The verified identity is bound to the invoice hash. A certified PDF report is generated with full audit trail, ready for regulatory inspection.
Start a verification session with a single POST request. We handle the OIDC4VP handshake, wallet interaction, and credential validation.
# Create a verification session curl -X POST https://api.validor.eu/v1/verify-invoice \ -H "x-api-key: $VALIDOR_API_KEY" \ -H "Content-Type: application/json" \ -d '{ "invoice_reference_id": "INV-2026-0042", "invoice_hash": "a1b2c3d4...sha256", "verification_template": "pid-minimal" }' # Response → session_id, qr_code_data, expires_at
"Validor transformed our invoice verification process. Secure, EUDI-ready, and the integration took our team less than a day."
"The zero-knowledge hash verification is a game changer. We prove invoice authenticity without ever exposing sensitive financial data."
"Finally a solution that takes digital identity seriously. The audit trails alone saved us hundreds of hours in regulatory prep."
The European Digital Identity (EUDI) Wallet is a secure, decentralized identity system that allows EU citizens to share verifiable credentials across borders with full control over their data. It is backed by eIDAS 2.0 regulation, with full availability across all EU Member States mandated by 2026.
Validor requires the invoice sender to prove their identity using a cryptographically signed credential from their EUDI Wallet via the OIDC4VP protocol, ensuring that only authorized entities are associated with invoices.
Yes. Validor is built on privacy-by-design principles. We use zero-knowledge hash verification and AES-256-GCM encryption. We only process the minimum data required and never store raw identity attributes in plaintext.
Absolutely. Validor provides a REST API and webhooks to integrate verification directly into SAP, Oracle, and other major ERP systems. A JavaScript SDK is also available for browser-based integrations.
Start verifying invoices with cryptographic identity proof. No credit card required.
