Google Calendar API Push Notifications registered but not pushed
<p>I am using Nodejs client library to connect to the calendar's API.
I've followed the instructions here: <a href="https://developers.google.com/google-apps/calendar/v3/push" rel="nofollow">https://developers.google.com/google-apps/calendar/v3/push</a>
and registered the domain that will get the notifications.
The following runs perfectly okay:</p>

<pre><code>calendar.events.watch({
        auth: context.auth,
        calendarId: 'primary',//context.googleCalendarId,
        resource: {
            id: contextId,
            type: 'web_hook',
            address: 'https://xxxxxxxx.com/api/google-calendar/webhook',
            params: {
                ttl: '36000'
            }
        }
    }, function (err, webhookProperties) {})
</code></pre>

<p>which I get the following JSON:</p>

<pre><code>{"kind":"api#channel","id":"56c9d4382bc6d42e8888888","resourceId":"vdVrqrQZDXIBrt288888888","resourceUri":"https://www.googleapis.com/calendar/v3/calendars/48jhhtq888888888@group.calendar.google.com/events?alt=json","expiration":"1456634213000"}
</code></pre>

<p>However any modifications to the events on the calendar (add,update,delete) doesn't result any push back to my server.</p>

<p>Any thought of what am I missing?</p>

<p>THX</p>
