Trying to use the package, I got the following response

In GoogleUrlShortener.php line 86:
Undefined property: stdClass::$id

and from the Google API:

(dump of $response at GoogleUrlShortnener.php:83)

object(stdClass)#1658 (1) {
["error"]=>
object(stdClass)#1657 (3) {
["errors"]=>
array(1) {
[0]=>
object(stdClass)#1654 (4) {
["domain"]=>
string(11) "usageLimits"
["reason"]=>
string(16) "ipRefererBlocked"
["message"]=>
string(148) "The request did not specify any referer. Please ensure that the client is sending referer or use the API Console to remove the referer restrictions."

["code"]=>
int(403)
["message"]=>
string(148) "The request did not specify any referer. Please ensure that the client is sending referer or use the API Console to remove the referer restrictions."

}

Detailed description

It is possible to solve it by indicating a generic referer via curl.

Possible implementation

I have added the following line:
(GoogleUrlShortnener.php:122)

    curl_setopt($this->curl, CURLOPT_REFERER, 'http://www.google.com');
