While Creating a webhook subscription, I am getting an error of
"errorCode": "SUB-520", "message": "Validation Token is not returned".

Did you return the validation token while creating the subscription? You have to return the validation token within 3 seconds. Otherwise, you would receive that error message. See the dev guide for sample code of how to return a validation token.
