Is there a contact ID?

[salevine]

I am working on an offline synchronization utility and woudl really like a unique id for each contact. Is there a persistent ID on each contact? I am missing it if it is there.

Thanks.

There is.

 

In the .Net library you call ContactEntry.Id.Content.

It is an Url.

Here is how it looks in the raw feed:

 

<id>
http://www.google.com/m8/feeds/contacts/userEmail/base/contactId
</id>

 

Seems it is the base Uri of the contact.

Take a look here:

http://code.google.com/apis/contacts/docs/3.0/developers_guide.html

search for :Retrieving all contacts

 

There is a sample XML that comes when you fetch a contact.

Not quite sure which library you use but there should be an identifier.

Thanks. Let me check that out. I am using the .NET library.
