Google API returning Access Not Configured

Question

I thought this would be straight forward, but for some reason I'm getting hammered on this one.

I'm using PHP + CURL to try and retrieve a list of Web Fonts. The code is simple:

        $url = "https://www.googleapis.com/webfonts/v1/webfonts?sort=popularity&key=MY_SERVER_APPS_KEY";

        $ch = curl_init();
        curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
        curl_setopt($ch, CURLOPT_HEADER, false);
        curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
        curl_setopt($ch, CURLOPT_URL, $url);
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
        $google_response = curl_exec($ch);
        curl_close($ch);            

The code is hitting Google, but $google_response always returns:

"error": {
    "code": 403,
    "errors": [
        {
            "domain": "usageLimits",
            "reason": "accessNotConfigured",
            "message": "Access Not Configured"
        }
    ],
    "message": "Access Not Configured"
}

I've set up a server access key and put both of my web server's API keys on it. (To verify my IP, I did a WGET on curlmyip.com) I've also enabled the "Web Fonts Developer API" from the Services tab.

Is there anything I could be overlooking?

Answer 1

I found the solution. Apparently I needed to register my server's IPv6 address, not the IPv4's. Worked without any code changes after adding them.

Answer 2

In my case the needed API was not enabled.

To enable:

1. Go to https://console.developers.google.com
2. Click the menu icon in the top left
3. Click API Manager from the menu
4. Search for your API in the search bar (e.g. YouTube Data API v3) and click on it
5. Once on the subpage for that API, click Enable in the top left

Answer 3

remove all "allowed Ips", then Any IP allowed
