How to Mock a Webhook Subscribe Callback URL in Python
Mock a webhook subscribe callback URL using Python's http.server to receive and parse POST requests sent by webhook providers.
import json
from http.server import BaseHTTPRequestHandler, HTTPServer
class WebhookHandler(BaseHTTPRequestHandler):
def do_POST(self):
content_length = int(self.headers.get('Content-Length', 0))
payload = json.loads(self.rfile.read(content_length)) if content_length else {}
print…Verify Webhook HMAC Signatures in Python
Create and verify HMAC-SHA256 signatures for webhook payloads using Python's hmac module, protecting against tampering.
import hashlib
import hmac
import json
SECRET = b"super-secret-webhook-key"
def create_signature(payload: bytes) -> str:
return hmac.new(SECRET, payload, hashlib.sha256).hexdigest()
def verify_signature(payload: bytes, signature: str) -> bool:
expected = create_signature(payload)
return hmac.compare_dig…Browse by section
