I was wondering, is it possible to set up a Mac OS X app, to get notified when a user makes changes to a Google Calendar. Like what you can do with EKEventStore?
There’s a query method + (id)queryForCalendarListWatchWithObject:(GTLCalendarChannel *) object, but I’m not really sure how you should set up the GTLCalendarChannel object.
Or is the only way, other than polling, to use push notifications?
Thanks in advance.
You can use Google Calendar API which provides push notifications that let you watch for changes to resources. This makes periodic polling unnecessary.
You can use this feature to improve the performance of your application. It allows you to eliminate the extra network and compute costs involved with polling resources to determine if they have changed. Whenever a watched resource changes, the Google Calendar API notifies your application.
To use this API, you need to:
Register the domain of your receiving URL. Before you can set up a push notification channel, you must register the domain for any URLs you plan to use to receive push notification messages.
Set up your receiving URL, or "Webhook" callback receiver. Whenever a watched resource changes, your application will receive a notification message describing the change. The Google Calendar API sends these messages as HTTPS POST requests to the URL you specified as the "address" for this notification channel.
Set up a notification channel for each resource endpoint you want to watch. To request push notifications, you need to set up a notification channel for each resource you want to watch. After your notification channels are set up, the Google Calendar API will inform your application when any watched resource changes.
When a calendar changes, it will notify your app and the app does an API call to get the update. You can use one of the Google API client libraries to utilize push notifications.
Check these documentation and blog about Google Calendar API Push notifications.
Hope this helps!

I wonder if I can measure my push notifications open and receive rate, sent by my backend. I use laravel right now and I use firebase admin SDK to send push notification from my backend server.
However, I cannot measure my push notification open and receive rate because it doesn't appeared in firebase console. Is there any way out like if google have API for us to grab the push notification data, or anything else ?
I'm also open for using another push notification service, as long they provide the analytics tools for the push notification campaign.
Thanks
Hi Kevin currently only the console allows automatic tracking of notification opens and other metrics. You could log these events yourself with the Google Analytics for Firebase SDK. Thanks for the feedback, this would be a useful feature.
I am developing a SPA webapp through which I add events to my users google calendar They have given permission for. However this is my first time using Google calendar API, and was unclear about how to retrieve my users existing events , or if they add new events or delete them. IS there an option to set a webhook within google calendar thus when the user makes any changes to the calendar I can receive the change. My current approach was to make multiple get requests but that seems very inefficient. How can I keep my app calendar in sync with all user created events.
You can set up a push notification to be alerted any time anything changes on one of your calendars. I looked into it before a little, if memory serves it doesn't alert you to a lot of particularly useful information (I don't believe it tells you exactly what changed and how). Check out the docs here: https://developers.google.com/google-apps/calendar/v3/push
What I ended up doing was setting up a cronjob and getting all of my calendars' events using the synctoken, which returns only the events that have changed since the last time I polled the API for events. https://developers.google.com/google-apps/calendar/v3/sync
If you are using the SyncToken in your request for data, all you get back is the events that have changed. There is an eventID in the Google records that you can use to connect the change to your event data.
In my application, I need to be able to add custom notifications to Yammer. Is there an undocumented way to add a notification through the Yammer Notifications REST API?
Notifications are sent when specific actions in Yammer are triggered, like when a message is received for a user a push notification will be sent to that user. There is no ability to manually generate push notifications for arbitrary events.
I want to trigger some script when new calendar event is created in Google Calendar (say calling some rest API that enters event information to my database). I do not want any kind of UI that triggers the script. Is it possible to achieve this using Google gadget since I do not want any UI? I would really appreciate the help as I am new to Google API.
Thanks a lot

Calendar API has something like notifications. See this link: Push Notifications. From documentation:
The Google Calendar API provides push notifications that let you watch
for changes to resources. You can use this feature to improve the
performance of your application. It allows you to eliminate the extra
network and compute costs involved with polling resources to determine
if they have changed. Whenever a watched resource changes, the Google
Calendar API notifies your application.
Google Calendar API (relevant docs) provides a watch endpoint that allows you to specify a webhook upon certain events.
To set up the webhook, you can call the Calendar API endpoint a POST request to https://www.googleapis.com/calendar/v3/calendars/calendarId/events/watch with the body
{
"id": string
"type": string,
"address": string
}
The "address" field tells Calendar what endpoint to call when there is a new Calendar event. You'll need to create and host this endpoint yourself.
Another option is to use a service like Zapier, which has fantastic integrations for Google Calendar and makes setting up a listener (i.e. a trigger) and corresponding action very simple.
My WP7 app needs to handle different types of push notification. Some of these are only relevant when the app is running but one type serves as a prompt to the user to start the app as well as needing to be handled while the app is running. Hence, when opening the push channel, my code calls BindToShellToast and registers event handlers for when both raw and toast notifications are received:
if (!_pushChannel.IsShellToastBound)
{
_pushChannel.BindToShellToast();
}
_pushChannel.HttpNotificationReceived += new EventHandler<HttpNotificationEventArgs>(pushChannel_HttpNotificationReceived);
_pushChannel.ShellToastNotificationReceived += new EventHandler<NotificationEventArgs>(pushChannel_ShellToastNotificationReceived);
Looking at the certification requirements, it appears that I have to provide a user setting to allow them to enable/disable not only push notifications in general, but also specifically toast notifications. See Additional requirements for specific app types for Windows Phone (requirement 6.2.1)
Since the user could potentially enable general push notifications but disable toast notifications, it seems to me that my server would need to send both a raw and a toast notification for the type that needs to be handled when the app is not running. This would make registering for the ShellToastNotificationReceived event pointless. Is my thinking correct here?
You should store a settings on your server for each registered device naming what type of notification the user allowed.
