Braintree WebHook configuration nodejs

I am trying to get Braintree Webhook responce on my app and update the users accordingly, But when i am creating any subscription (Activation) or canceling any subscription its not triggerring my webhook url. Note :- tryied check url from Braintree interface its working fine and calling my apps webhook url.

I am using this code to check the kind of notification

gateway.webhookNotification.parse(
    req.body.bt_signature,
    req.body.bt_payload,
    function (err, webhookNotification) {
      console.log("[Webhook Received " + webhookNotification.timestamp + "] | Kind: " + webhookNotification.kind);
}

So as per my information, this code will be telling me about the kind or notification and accordingly i can take action. checkd fields on webhook for Braintree is Charged Successfully Charged Unsuccessfully Expired Went Active Went Past Due.

Waiting for guidance

Thanks in advance
