Not receiving Google OAuth refresh token

Question

I want to get the access token from Google. The Google API says that to get the access token, send the code and other parameters to token generating page, and the response

Answer 1

I searched a long night and this is doing the trick:

Modified user-example.php from admin-sdk

$client->setAccessType('offline');
$client->setApprovalPrompt('force');
$authUrl = $client->createAuthUrl();
echo "Connect Me!";

then you get the code at the redirect url and the authenticating with the code and getting the refresh token

$client()->authenticate($_GET['code']);
echo $client()->getRefreshToken();

You should store it now ;)

When your accesskey times out just do

$client->refreshToken($theRefreshTokenYouHadStored);
