App Engine + Webmaster Tools

I've been trying for 开发者_如何学运维a while now to get my Python App Engine app onto the Chrome Web Store, however, when I try to upload, Google tells me I need to confirm that its my domain (I'm on an appspot.com domain). I have tried the first 3 methods (meta tag, file, and analytics) in several different ways but they haven't worked. Is there any way around this? Or, rather, how can I verify an App Engine domain?
