Usage

FastAPI example

from fastapi import FastAPI, Request, Header, HTTPException
from paddle_webhook_signature_verifier 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_signature_verifier 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_signature_verifier 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"})
