It is working fine for email client (outlook and Thunderbird) but not working for gmail calendar. Please give you suggestions to delete from gmail calendar

Answer 1

Right well, Thunderbird and outlook are both programs with calendars that are 'on the computer'. So they can probably do magical things with attachments such as preview and in this case remove/add/accept events. Gmail being online can't do such things browser security etc. So don't think you have many options.

Google Calendar does have an API which you could use. https://developers.google.com/google-apps/calendar/quickstart/php

I would suspect you'll encounter similar problems for the Microsoft live calendar or perhaps other online calendars that people might use.

In the end you either need to supply a way to 'link' your application to the persons online calendar and use the API supplied (if it exists) or perhaps dodge the question entirely by supplying an online ics file through your own API that people can embed into there calendar (I know Outlook can do this). Or just don't have the ics files and instead just the calendar in your own application (which I think is where the ics files are coming from?)

Just a google seems to say the answer is a no -https://productforums.google.com/forum/#!topic/calendar/9uHpOige9Co
