I am using PHP SDK for docusign integration in laravel. I am trying to download signed document envelop in my public folder. I am getting the PDF content after following the steps. But when i tried to save it in PDF file using file_put_contents then its save a PDF file but after opening it gives me PDF document is damaged.
$ch = curl_init();
$headers = array(
'Content-Type: application/pdf',
'Authorization: Bearer '.$_SESSION['docusign_auth_code']
);
curl_setopt($ch, CURLOPT_URL, 'https://demo.docusign.net/restapi/v2/accounts/{account_id}/envelopes/{envelop_id}/documents/1/');
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "GET");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
// Timeout in seconds
curl_setopt($ch, CURLOPT_TIMEOUT, 30);
$file_content = curl_exec($ch);
file_put_contents("my_document.pdf", ($file_content));
return $file_content;
I have tried above code and this code is working but PDF file is giving error on opening.
