+# FAQ 
+## Webhooks vs HTTP requests?
+
+We use Webhooks for executing tasks as the expected runtime of these jobs can exceed default HTTP timeouts (1 minute)
+
+## How do we handle webhook authentication? (ie how can we handle callbacks?)
+
+- a python example for how to generate the signature:
+
+```python
+def validate_skyvern_request_headers(request: Request) -> bool:
+		header_skyvern_signature = request.headers["x-skyvern-signature"]
+		payload = request.body() # this is a bytes
+		hash_obj = hmac.new(SKYVERN_API_KEY.encode("utf-8"), msg=payload, digestmod=hashlib.sha256)
+    client_generated_signature = hash_obj.hexdigest()
+		return header_skyvern_signature == client_generated_signature
+```
+
+SKYVERN_API_KEY: this is the [api key](/running-tasks/introduction) specific to your organization
