Google Contacts Data API

Comments (8)

Dear all my friendly neighborhood web developers out there.  Please don’t ever ask me for my Google login and password again.  Instead, please implement the Google Contact API.  While you are at it, please consider implementing the Windows Live Contacts API.  I went looking for the Yahoo one (it’s probably in the Mail stuff somewhere) also but gave up and figured I’d just point you to the MyBlogLog API which has plenty of fun, juicy data available.

That’ll keep you busy for a while.

    This is awesome! I've been wanting Google to do this for a long time. I want to tell all my web services (and client apps like Apple Address Book) to just “subscribe” to my contacts on Gmail. If I add a new contact in gmail — which happens automatically when I email someone new — I'd love it if twitter just found out and emailed me to let me know if I'd like to follow them on twitter.

    I don't understand how it can do this without asking for username & password, unless you are logged into google parallel on a tabbed browser

      Basically, you have the app you want to integrate with tell google that it wants access to your data. The app redirects you to google, and has you log in. It passes information back and forth to authenticate the service (without using your password), and then can use your data. There's an explanation of their authentication mechanism at: http://code.google.com/apis/gdata/auth.html

    Do you know how to do language support ? e.g. how to show the login screen in French?
