  The comment by @krishna actualy shows how to get the event ID and it works. But how to get the event ID in <a href="https://www.google.com/calendar/" rel="nofollow noreferrer">https://www.google.com/calendar/</a> URL not in the URL(<a href="https://www.google.com/calendar/render?gsessionid=OK&amp;eventdeb=1" rel="nofollow noreferrer">https://www.google.com/calendar/render?gsessionid=OK&amp;eventdeb=1</a>) as told by Krishna.</p>
