I need to get the unique URL identifier for the product that is created after inserting an item into Google Base using the Zend_Gdata_Gbase library.

I can't seem to do this. I am finding a startling lack of documentation online about manipulating the objects used in these applications.

The url that I add to the object does not work to retrieve the base item later, which is why I need to get the one that google generates upon submission.

I am writing a program that will need to be able to delete content at a later date, and thus will need to store that information in order to keep the website synced with the Google Base feed.

Thanks in advance for any help.
