Google Calendar API Push notifications issue

Question

I am trying to implement push notifications feature in Google calendar api. I have also whitelisted my domain https://www.skygazr.com in webmaster tools and cloud console.

Now while am trying to create a working copy of Watch request it is giving me a webhookUrlUnauthorized error.

Please check the below request and response.

   }
  ],
  "code": 401,

 }
}
