Hello All,

I want to send event invitation to Google user, using google calendar API.
for this,
I am using Google calendar API in php,
for inserting event in the google calendar .
I have used php-client libraries https://developers.google.com/google-apps/calendar/downloads
But problem with this is : it require login.

So how can I use this without login requirmnet ? or am missing something?
coz my aim is simply send invitation which should get added to Calendar (with or without notification)

Im pretty sure google sec policy will not allow you to interact without logging in. Not 100% sure.. You may find a work around use php & cURL
