Google Calendar API: Editing a single occurrence of a recurring event

Using the Google Calendar API, how can I edit a single occurrence of a recurring event? (the web interface al开发者_如何学Clows me to do that)

Reading through some of the google forums on this I came across an answer from a google employee:

What you can also do is to retrieve the events by adding the query parameter 'singleevents=true' to the feed URL. This will expand the recurring events into multiple events. http://code.google.com/apis/calendar/data/2.0/reference.html#Parameters

You will just have to modify the desired events and it will create the exception.

About the "Forbidden g:originalEvent [2010-02-08 06:00:00] does NOT correspond to an instance of the recurring event": this mean that the When object set in the OriginalEvent doesn't match the time of the occurrence of the recurring event.
