PHP AdobeSign API :: transientDocuments with OAuth2.0

Question

I am using PHP OAuth2.0 Adobesign API for sending pdf to user for e-signature purpose.

I successfully generate auth token and refresh token by following basic OAuth2 steps.

Now I am facing issue while trying to send pdf transientDocuments using curl code. Below is my sample code:

define("CALLBACK_URL", "https://www.getdadstrong.com/vipin/test.php");
define("AUTH_URL", "https://api.in1.echosign.com/api/rest/v6/transientDocuments");
define("ACCESS_TOKEN_URL", "http://api.in1.echosign.com/oauth/token");
define("CLIENT_ID", "MY_CLIENT_ID");
define("CLIENT_SECRET", "MY_CLIENT_SECRET");
define("SCOPE", "agreement_send:account"); // optional


function getToken(){

 $curlFILE = curl_init();
 $params = array(
    CURLOPT_URL =>  AUTH_URL,
    CURLOPT_RETURNTRANSFER => true,
    CURLOPT_MAXREDIRS => 10,
    CURLOPT_TIMEOUT => 30,
    CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
    CURLOPT_CUSTOMREQUEST => "POST",
    CURLOPT_NOBODY => false, 

    CURLOPT_HTTPHEADER => array(
    "Authorization: Bearer MY_SECURE_TOKEN", 
      "cache-control: no-cache",
      "content-type: multipart/form-data",
      "Content-Disposition: form-data; name='file'; filename='MyPDF.pdf'",
    ),
    CURLOPT_POSTFIELDS => array (
                // 'filename' => new CURLFile('./MyPDF.pdf') 
                'filename' => new CURLFile('./MyPDF.pdf','application/pdf','MyFile') 
        ),
    CURLOPT_SSL_VERIFYPEER => FALSE,
    CURLOPT_SSL_VERIFYHOST => FALSE 
  );

    curl_setopt_array($curlFILE, $params);
    $response = curl_exec($curlFILE);


    curl_close($curlFILE);
    $err = curl_error($curlFILE);
    if ($err) {
        echo "<br/> cURL Error #01: " . $err;
    } 
    echo '<pre>';
    var_dump($err);  
    var_dump($response);  
    echo '<pre>';

  }
getToken();

Output:

{
    "code": "NO_FILE_CONTENT",
    "message": "Must provide file body"
}

Finally I come to know Adobe Esign with V6 having some issue with this method. So I switch to V5 and make some little modification in my code. It is working for me.

<?php
define("AUTH_URL", "https://api.na2.echosign.com/api/rest/v5/transientDocuments");

$url = AUTH_URL;
$header =array(
        "Authorization: Bearer 3AAAB6hBTt666543359kgBzroaNxqyezwBRdsdsdssssssssss6767gGy7CNdERHxqz1r5lOzmyxI7hfQ22zsyCDvnG_HRc8m9B7UBRJuGy", 
        "cache-control: no-cache",
        "content-type: multipart/form-data",
        "Content-Disposition: form-data; name='File'; filename='MyPDF.pdf'",
    );

$filePath= '@'.file_get_contents('MyPDF.pdf');
$fields = array('File' => $filePath,'Mime-Type' => 'application/pdf', 'File-Name' => 'MyPDF.pdf');

$resource = curl_init();
curl_setopt_array($resource, array(
  CURLOPT_URL => $url,
  CURLOPT_RETURNTRANSFER => true,
  CURLOPT_ENCODING => "",
  CURLOPT_MAXREDIRS => 10,
  CURLOPT_TIMEOUT => 30,
  CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
  CURLOPT_CUSTOMREQUEST => "POST",
  CURLOPT_POSTFIELDS => $fields,
  CURLOPT_HTTPHEADER => $header
));


$res = curl_exec($resource);
$result = json_decode($res,true);
echo "<pre>";
print_r($result);
echo "</pre>";
curl_close($resource);
?>

Output:

Array
(
    [transientDocumentId] => 3AA777777777777gwxctQX8kTYj2e3Esgc5_HbvKgKK_oaIccNqr2JwWJK8bUXn779OMvyFMJG2VONbbbMqO-bo_GoKJP-wfYszcQtg7tbJ8sc8YxTwQPm3kV77777ThgQy5ZoeHb_km-zmitgdSkf7sLYp0vCO8CAbvYQVzd3OpU6zJ-Mv54VoVKvsYUFsfhfhgK]epKpCHnvKWvn37fghfg777876rV2QYyh9bkApotXvSzxndXNQbUTmAcpP1Jq-WlXsVdGleKjHoEMoDgfhfghIOYQFxy5eeOtctqwtxC9MUWjioGV6FW6ZtoGm0ijqGU*
