How to see if domain is using Google Apps with Python

Within my Python GAE application I need to know if a user's domain is a Google Apps domain. Until now I've been sending a request to https://www.google.com/a/domainName/ServiceLogin. If the response had "Sorry, you've reached a login page for a domain that isn't using Google Apps" included, the domain was not using Google Apps. However, recently I noticed that this method doesn't seem to work anymore. Do any alternative methods exist?

Thanks

Solution

Include email in the list of scopes you request from the user. In the response token there will be an hd parameter if it's a Google Apps account.
