    // Create new account
    $account = $client->createAccount(
        new HelloSign\Account($email),
        $client_id,
        $client_secret
    );

    // Get OAuth token
    $token = $account->getOAuthData();
} else {
    // Create the OAuthTokenRequest object
    $oauth_request = new HelloSign\OAuthTokenRequest(array(
        'code'          => $code,
        'state'         => $state,
        'client_id'     => $client_id,
        'client_secret' => $client_secret
    ));

    // Request OAuth token for the first time
    $token = $client->requestOAuthToken($oauth_request);
}

// Export token to array, store it to use later
$hellosign_oauth = $token->toArray();

// Populate token from array
$token = new HelloSign\OAuthToken($hellosign_oauth);

// Refresh token if it expired
$client->refreshOAuthToken($token);

// Provide the user's OAuth access token to the client
$client = new HelloSign\Client($token);
```

// Grab the signature ID for the signature page that will be embedded in the
// page (for the demo, we'll just use the first one)
$signatures   = $response->getSignatures();
$signature_id = $signatures[0]->getId();

// Retrieve the URL to sign the document
