I am trying to find a way to get notifications pushed to a server whenever users update/delete their google tasks.
For Google Calendar events, you can create a watch to get changes to Events resources and notifications pushed to the webhook you specify.
Is there something like this we can use for Google Tasks?

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.
I wanted to synchronize my contacts from mailchimp to my app.
I did this by periodically asking Mailchimp if any contacts were updated or created .
Now, I want to do it using the Mailchimp's webhooks.
I have created a webhook in mailchimp and tested it and it works well when I do some changes as Admin using the Mailchimp UI, but when I add or update any contacts using import contacts functionality, I don't receive any notifications.
Mailchimp's webhook API says that they send notifications only when a change is made
by a subscriber
by an account admin
via the API
so, since I'm not getting the notifications I used to get using the previous method, is changing to webhooks a bad option?
Is there any way that I could get the notifications I used to get from my old method, using Mailchimp's webhooks?
Webhooks may have been omitted from imports to try and protect users from inadvertently DDoSiNg the hook destinations on large imports.
In regards to keeping these two data sets in parity, because webhooks don't have a trigger for import events, I might first suggest exploring another update method for adding subscriber data to the list in MailChimp.
Perhaps looking to the Batch operation options in MailChimp's API:
http://developer.mailchimp.com/documentation/mailchimp/reference/batches/
http://developer.mailchimp.com/documentation/mailchimp/guides/how-to-use-batch-operations/?utm_source=mc-api&utm_medium=docs&utm_campaign=apidocs&_ga=1.112643975.2008383502.1487629834
As this should allow large updates while keeping the external app abreast of any updates via the triggered webhooks.

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 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.
