A Python package for verifying Paddle webhook signature

Paddle webhook signature verifier for Python

A Python package for verifying Paddle webhook signatures. Official Paddle SDKs are only available for PHP and Node.js. This packagage helps server side verification of Paddle webhook signatures if you are using a Python based backend framework like Django, Flask, FastAPI, etc.

Usage

FastAPI example

from fastapi import FastAPI, Request, Header, HTTPException
from paddle_webhook_verification.handler import WebhookHandler

app = FastAPI()
handler = WebhookHandler(secret_key=b'your_secret_key')

@app.post("/webhook")
async def webhook(request: Request, paddle_signature: str = Header(None)):
    try:
        body_bytes = await request.body()
        handler.verify_paddle_signature(paddle_signature, body_bytes)
        return {"status": "ok"}
    except ValueError as e:
        raise HTTPException(status_code=400, detail=str(e))

Flask example

from flask import Flask, request, abort
from paddle_webhook_verification.handler import WebhookHandler

app = Flask(__name__)
handler = WebhookHandler(secret_key=b'your_secret_key')

@app.route("/webhook", methods=["POST"])
def webhook():
    try:
        paddle_signature = request.headers.get("Paddle-Signature")
        body_bytes = request.get_data()
        handler.verify_paddle_signature(paddle_signature, body_bytes)
        return {"status": "ok"}, 200
    except ValueError as e:
        abort(400, description=str(e))

Django example

from django.http import JsonResponse
from paddle_webhook_verification.handler import WebhookHandler

handler = WebhookHandler(secret_key=b'your_secret_key')

def webhook(request):
    try:
        paddle_signature = request.headers.get("Paddle-Signature")
        body_bytes = request.body
        handler.verify_paddle_signature(paddle_signature, body_bytes)
        return JsonResponse({"status": "ok"})
    except ValueError as e:
        return JsonResponse({"error": str(e)}, status=400)
