I'm creating events on google calendar using the Google Calendar API, which is working fine. When I modify one of those events within Google Calendar, Google can email me an even update with an .ics file.
Is there a way determine the eventid via the email or ics file, and tie it back to the eventid when i created the event using the API?
For example, I want to automatically receive event change emails sent from Google Calendar, and update the event in my database (where I store the eventid returned from adding the event using the API)
