I am trying to download and sync contacts between Google Contacts and my software. What I am looking for is a "primary key" of sorts so that I will be able to identify the contacts between the two systems no matter what has changed.
Right now it looks like I could use SelfUri, but I was wondering if someone else had any more insight into this? I tried using the Id property but that does not seem to contain any usable information. Thanks!
