Can I use JSON to pull events from a public Google Calendar?

Hello everyone, 

I have been experimenting with building enterprise apps with CoronaSdk - one of the things I am trying to do is link up a calendar from a 3rd party source (IE Google Calendar); I believe the default Google Calendar API allows for this, but I’m not sure exactly how to get the URL needed to call the data from Google’s side. I have been looking everywhere and can’t seem to find the answer. 

Also, 

Is this the best way to get calendar entries in Corona SDK ? Is there calendar support that I’m missing? 

Thanks for your help and suggestions!
