Unfortunately whatever you're using to do so has a HTTP User-Agent header value that is too generic or otherwise excessively suspicious.

EDIT: A sample project of this, and Part 2, can be found here or here. Setup#Google OAuth token#First what you need is, to register your application with Google, so you’ll get a Token that you can use to authorize later calls to Google services.
