I'm trying to 'Add Domain' to a google app I have. https://developers.google.com/appengine/articles/domains describes how to do this. From the 'app engine' page, Administration -> Domain Setup -> Add Domain I put in my domain name after 'selecting an account' and supplying my password, it returns a 'Google Accounts' page with the message 'invalid request' -- not very helpful.
I'm trying to use/add a domain that I own, but google has not heard of before. The scarce document talks about 'registering the domain' with Google apps, but doesn't say how. Are they implying that you can only add domains that google already manages? (I don't see how they could control my domain to get requests from it directed to their server farm.
How do I make my google app respond requests to a domain that I own?
