Starting over the weekend, all of my app's calls to the GData APIs for Google Analytics result in an "Insufficient quota to proceed" error message. Additionally, when I use the Data Feed Query Explorer to pull down any data, the "Get Data" button appears unresponsive. When I open up the JS console on my browser, though, I see that clicking the button does issue an HTTP request, but the response has a "Insufficient quota to proceed" error message.
In my app, the URL that I use to request data has the parameter "key=<API_key>" (with my actual sever key value of course), but my Google API console (
https://code.google.com/apis/console) reports zero usage for that key. For example, my URLs (with sensitive data snipped out) look like:
Our app uses Google Analytics data in a way that is critical to our core users.
Note: I have posted an issue with the same symptoms before on Feb 6 (
