Peppol Participant Lookup

The Peppol Participant Lookup extension is an e-invoicing utility tool designed to search and verify participant registration status across the international Peppol (Pan-European Public Procurement On-Line) Network. When sending electronic invoices or business documents via Peppol, businesses must know whether the receiving company is active on the network and what exact document formats they can accept. This extension queries the official Peppol SML (Service Metadata Locator) and SMP (Service Metadata Publisher) registries in real time to fetch standard parameters: Registration Verification: confirms whether an organization's Peppol ID (such as a VAT number, Belgian enterprise number, or ISO scheme code) exists. Document Capabilities: lists all e-document types the participant is configured to receive (e.g., Peppol BIS Billing UBL Invoices, Credit Notes, or country-specific CIUS formats). Network Endpoints & Technical Keys: retrieves underlying SMP host URLs, transport profiles, AS4 service endpoints, and cryptographic public keys/certificates. Comfort & Usability Features The interface is built to minimize manual workflow steps and streamline quick lookups: Auto-Detection Support: automatic detection mode for networks and schemes means you can paste raw or formatted Peppol IDs without needing to manually configure network paths. Context Menu Integration (Right-Click Lookup): allows you to highlight any Peppol ID directly on any webpage or browser tab, right-click, and query it instantly without opening the extension pop-up or switching tabs. Inline Error Prevention: clear error feedback (such as missing manifest icon alerts or invalid format notices) ensures you do not submit broken technical parameters. Quick History Access: saves recent search terms at the bottom of the interface for single-click repeated lookups. Security Checks: built-in SMP signature verification provides peace of mind by validating response authenticity against official PKI trust chains.
