I have already whitelisted my domain www.example.com
I have already got ssl certificate which is mandatory to receive push notifications
I googled about this issue , but could not find much help.
Posted same question on google group of calender api, but no response yet. https://groups.google.com/forum/#!topic/google-calendar-api/ZHKwm2xWuNE

can anybody guide, whats wrong with request ?

回答1:

when you try with API Explorer,it will not use your OAuth2.0 project keys where you have registerd whitelisted domains, maybe it would use another keys

try to use client/lib

回答2:

Your auth token may be incorrect. Please make sure you are using correct auth token for the calendar you are trying to set watch for

回答3:

The one step I was missing to get this working was to actually enable the Calendar API in the console. The 401 push.webhookUrlUnauthorized error is really not helpful here.

回答4:

Finally It worked for me , cause of error "Unauthorized WebHook callback channel" was in Configuration of Project in

Go to Google Developers Console.
Click your project name
Click "API & Auth" Menu on left
then click on sub menu "Push"
Click on Add Domains button which Allows webhook notifications to be sent to the entered domains

Happy coding :)
