title: Google Apps Marketplace Button returning 403 Forbidden
body: <p>I'm attempting to add the Google Apps Marketplace Button mentioned <a href="https://developers.google.com/apps-marketplace/button" rel="nofollow">here</a> into my app, but even with the most basic setup it results in a 403 Forbidden Error. Is there a particular scope that this button requires or another step I need to take in order to get this working?</p>
