Google contacts

Check out a web search for google contacts plus the programming language you prefer. Probably you won't find a free ready-to-use script, but there are several tutorials.

Accessing google contacts is anything but easy, just writing some script code doesn't do the job. You have to set up a google devoloper account along with an application, as well as a web server to perform OAuth login.

I moved this thread to the "common" area while this is not an asterisk issue.
