google analytics api fails to return segment data

I'm trying to use Google Analytics API to retrieve data for my custom segments.

They say here http://code.google.com/apis/analytics/docs/gdata/gdataReferenceAccountFeed.html开发者_StackOverflow#accountResponse that all the segments are listed in the account feed response. But mine doesn't contain them.

Has anyone else had this problem and know a way to get the data out from them?

Thanks,

Beth

Make sure you add GData-Version: 2 in your header.
