Twitter OAuth...

[Mr. Goodie2Shoes]

I am getting this error:

Could not authenticate with OAuth.

and I am unable to fix the problem... any helping hand?
and the coding:

<?php
class xenCODE_Socialize_Helper_Twitter
{
    private static $url = 'https://api.twitter.com/1/statuses/update.json';
    public static function tweet($message)
    {

        try
        {
            $client = XenForo_Helper_Http::getClient(self::$url);
            foreach(self::getParams($message) as $key => $value)
            {
                $client->setParameterPost($key, $value);
            }

            return $response->getBody();
        }

        }
    }

        $keyParts = array(
            $options->xenCODE_XS_TCS,
            $options->xenCODE_XS_TAS
        );
        $keyParts = self::urlencode_rfc3986($keyParts);
        $key = implode('&', $keyParts);
    return base64_encode(hash_hmac('sha1', self::getBaseString($message), $key, true));
    }
   
    private static function getParams($message)
    {
        $options = XenForo_Application::get('options');
        return array(

okay, I made some slight changes... but no luck
