Overview
Learn how the Bizzlink API works and what you can do with it.
The Bizzlink API is a PEPPOL e-Invoicing microservice that enables you to create, validate, convert, and send electronic documents through the Peppol network.
What is Peppol?
Peppol (Pan-European Public Procurement OnLine) is an international framework that enables businesses and governments to exchange standardized electronic documents — primarily invoices — across borders. It is widely adopted in the EU and is mandatory for B2G invoicing in many countries including Luxembourg, Germany, France, and the Netherlands.
What can you do with the Bizzlink API?
Create & Send Invoices
Send a JSON payload, and the API generates a fully compliant UBL 2.1 Invoice or Credit Note XML, validates it against PEPPOL BIS 3.0 Schematron rules, and transmits it through the Peppol network.
Convert Existing Documents
Already have ZUGFeRD, Factur-X, or CII documents? The API converts them to UBL 2.1 format automatically. You can even upload ZUGFeRD PDF/A-3 files and the API will extract the embedded CII XML.
Validate Before Sending
Run your UBL XML through PEPPOL Schematron validation independently. Catch errors before they hit the network.
Multiple Input Formats
| Format | Description |
|---|---|
| JSON | Simplified invoice/credit-note JSON → UBL 2.1 XML |
| UBL 2.1 XML | Send pre-built UBL directly |
| UBL 2.1 JSON v2 | OASIS UBL-2.1-JSON-v2.0 format |
| ZUGFeRD/CII XML | Cross Industry Invoice XML |
| ZUGFeRD/Factur-X PDF | PDF/A-3 with embedded CII XML |
Peppol Participant Identification
Every sender and receiver on the Peppol network is identified by a participant ID consisting of two parts:
| Field | Description | Example |
|---|---|---|
schemeId | Identifier scheme code | 0088 (GLN), 0192 (NL KVK), 9930 (LU TVA) |
participantId | The actual identifier | 1234567890123 |
These are used as PEPPOL EndpointID values in UBL documents.
