I’m not able to validate the webhook signature in python. Every time I compute HMAC hash for request content by using SHA256, the result does not match with signature passed by Orchestrator from webhook. Below is the code: import hmac, json, locale import hashlib import base64 digest = hmac.new(b"[Key set in orchestrator webhook]", str(event.body).encode(‘utf-8’), hashlib.sha256).digest() string_signature = base64.b64encode(digest) print(string_signature) print(hmac.compare_digest(string_signature, event.signature)) Note: Webhook listener is implemented in AWS with the help of API Gateway + Lambda (Python) Please can someone help on this? Many thanks in advance!
