Greqo Docs : Requesting a Google Auth Token

For Google Data services, like the new Blogger API, any request or transaction must be accompanied by an authentication token set as a header for the request. This token must be requested using one of two methods promoted by Google as part of their GData API. The request_clientlogin_token method will request and store a token for use with any Blogger API requests.

Sample Code

$GreqoBlogger = new GreqoBlogger($debug=1);
$GreqoBlogger->email = 'user@gmail.com';
$GreqoBlogger->password = '*********';

if ( $GreqoBlogger->request_clientlogin_token($service='blogger', $force=1) )
    $_HTML['stdout'] .= '<p class="success">token for user ' .$GreqoBlogger->email. ' retrieved</p>';
    #$_HTML['stdout'] .= '<p class="success">token: ' .$_SESSION['GDATA']['auth_token']. '</p>';
    $_HTML['stdout'] .= '<p class="failure">unable to retrieve authentication token (devs have been notified)</p>';


string request_clientlogin_token( string Google service[, int force] )

This method requests an authentication token from the Google servers using the ClientLogin interface

If the optional force parameter is set to 0 and the token has already been requested, it will return the current token. If force is set to 1, it will request a new token. The default is 1.

It returns the token itself as a string if the request is successful and 0 if it fails or there is an error. It also assigns the token to $_SESSION['GDATA']['auth_token'] for reuse within the same session.


How often do you need to renew an authentication token? The answer seems to be: when in doubt, get a new token. See this post.
