Handle Push Notification Response

[Himanshu Jain]

Hi,

I am developing ASP.NET application for Google calendar integration. as I am able to created a proper watch channel between my app and Google calendar watch service, but i am little bit confused, how will it communicate with my application. Means if any one change to the Google calendar then how can i get the proper response i.e. what are the events that have changed or what has changed over the Google calendar. I am specifing my code below for creating channel.

Channel channel = new Channel();

channel.Id = System.Guid.NewGuid().ToString();

channel.Type = "web_hook";

channel.Address = "https://www.XXX.net/Account-Calendar.aspx";

EventsResource.WatchRequest request = service.Events.Watch(channel, "XXX...@gmail.com");

request.Oauth_token = token;

Channel ch1 = request.Execute();

Hello,
I'll put this straight. When a change over watched resources occurs, google will send POST request to your channel.Adress, where you have to make IncrementalSync since that POST does NOT contain any data about the changes.
Hope this answer helps you to clarify your question.
