Installation

pip install factpulse

Quick Start

import base64
from factpulse_helpers import FactPulseClient

# Create the client
client = FactPulseClient(
    email="your_email@example.com",
    password="your_password",
    client_uid="your-client-uuid",  # From dashboard: Configuration > Clients
)

# Read your source PDF
with open("source_invoice.pdf", "rb") as f:
    pdf_b64 = base64.b64encode(f.read()).decode()

# Generate Factur-X and submit to PDP in one call
result = client.post(
    "processing/invoices/submit-complete-async",
    invoiceData={
        "number": "INV-2025-001",
        "supplier": {
            "name": "ACME Corporation",
            "siret": "12345678901234",
            "iban": "FR7630001007941234567890185",
            "routing_address": "12345678901234",
        },
        "recipient": {
            "name": "Client Company SA",
            "siret": "98765432109876",
            "routing_address": "98765432109876",
        },
        "lines": [
            {
                "description": "Consulting services",
                "quantity": 10,
                "unitPrice": 100.0,
                "vatRate": 20.0,
            }
        ],
    },
    sourcePdf=pdf_b64,
    profile="EN16931",
    destination={"type": "afnor"},
)

# PDF is in result["content"] (auto-polled, auto-decoded from base64)
with open("facturx_invoice.pdf", "wb") as f:
    f.write(result["content"])

print(f"Flow ID: {result['afnorResult']['flowId']}")

API Methods

The SDK provides two generic methods that map directly to API endpoints:

# POST /api/v1/{path}
result = client.post("path/to/endpoint", key1=value1, key2=value2)

# GET /api/v1/{path}
result = client.get("path/to/endpoint", param1=value1)

Common Endpoints

Webhooks

Instead of polling, you can receive results via webhook by adding callbackUrl:

# Submit with webhook - returns immediately
result = client.post(
    "processing/invoices/submit-complete-async",
    invoiceData=invoice_data,
    sourcePdf=pdf_b64,
    destination={"type": "afnor"},
    callbackUrl="https://your-server.com/webhook/factpulse",
    webhookMode="INLINE",  # or "DOWNLOAD_URL"
)

task_id = result["taskId"]
# Result will be POSTed to your webhook URL

Webhook Receiver Example (Flask)

import hmac
import hashlib
from flask import Flask, request, jsonify

app = Flask(__name__)
WEBHOOK_SECRET = "your-shared-secret"

def verify_signature(payload: bytes, signature: str) -> bool:
    if not signature.startswith("sha256="):
        return False
    expected = hmac.new(WEBHOOK_SECRET.encode(), payload, hashlib.sha256).hexdigest()
    return hmac.compare_digest(signature[7:], expected)

@app.route("/webhook/factpulse", methods=["POST"])
def webhook_handler():
    signature = request.headers.get("X-Webhook-Signature", "")
    if not verify_signature(request.data, signature):
        return jsonify({"error": "Invalid signature"}), 401

    event = request.json
    event_type = event["event_type"]
    data = event["data"]

    if event_type == "submission.completed":
        flow_id = data.get("afnorResult", {}).get("flowId")
        print(f"Invoice submitted: {flow_id}")
    elif event_type == "submission.failed":
        print(f"Submission failed: {data.get('error')}")

    return jsonify({"status": "received"})

Webhook Event Types

Zero-Storage Mode

Pass PDP credentials directly in the request (no server-side storage):

result = client.post(
    "processing/invoices/submit-complete-async",
    invoiceData=invoice_data,
    sourcePdf=pdf_b64,
    destination={
        "type": "afnor",
        "flowServiceUrl": "https://api.pdp.example.com/flow/v1",
        "tokenUrl": "https://auth.pdp.example.com/oauth/token",
        "clientId": "your_pdp_client_id",
        "clientSecret": "your_pdp_client_secret",
    },
)

Error Handling

from factpulse_helpers import FactPulseClient, FactPulseError

try:
    result = client.post("processing/validate-xml", xmlContent=xml_string)
except FactPulseError as e:
    print(f"Error: {e}")
    print(f"Status code: {e.status_code}")
    print(f"Details: {e.details}")  # Validation errors list

Available Helpers

The SDK provides the following helper classes:

• FactPulseClient: Main HTTP client with auto-auth and polling
• FactPulseError: Base exception class
• FactPulseAuthError: Authentication failure
• FactPulseValidationError: Validation errors with details
• FactPulsePollingTimeout: Task polling timeout
