Quick Start

The factpulse_helpers module provides a simplified API with automatic authentication and polling:

from factpulse_helpers import FactPulseClient

# Create the client
client = FactPulseClient(
    email="[e-mail]",
    password="your_password"
)

# Build the invoice using simplified format (auto-calculates totals)
invoice_data = {
    "number": "INV-2025-001",
    "supplier": {
        "name": "My Company SAS",
        "siret": "12345678901234",
        "iban": "FR7630001007941234567890185",
    },
    "recipient": {
        "name": "Client SARL",
        "siret": "98765432109876",
    },
    "lines": [
        {
            "description": "Consulting services",
            "quantity": 10,
            "unitPrice": 100.0,
            "vatRate": 20,
        }
    ],
}

# Generate the Factur-X PDF
pdf_bytes = client.generate_facturx(
    invoice_data=invoice_data,
    pdf_source="source_invoice.pdf",
)

with open("facturx_invoice.pdf", "wb") as f:
    f.write(pdf_bytes)
