In case you’re not reading the Mogo blog, I posted a tutorial over there yesterday about how we integrate Google Analytics with Rails using OAuth and Garb . It’s not a terribly arduous process, but if you haven’t done much work with OAuth it can be confusing, and there are a couple unique Googly things about it that might otherwise trip you up.
The post includes complete code for an OAuth-backed authorizations controller too, which should help you get up and running quickly. And fwiw, it should actually be applicable to all the Google Data APIs, not just Google Analytics. Just change the request token scope.
And yeah, I really need to get back to blogging on a semi-regular basis, too.
