如何与docusign和php集成

我对此非常陌生，尝试将docusign与php集成，我使用以下代码

$integratorKey = 'XXXX';
$email = 'mageshkumar.it@gmail.com';
$password = 'XXXX';
$name = "mageshkumar";
// copy the templateId of an existing template here
$templateId = "C9D9D181-CE57-.....................";
// construct the authentication header:
$header = "<DocuSignCredentials><Username>" . $email . "</Username><Password>" . $password . "</Password><IntegratorKey>" . $integratorKey . "</IntegratorKey></DocuSignCredentials>";

我只想得到收到的文件的状态更新。
