Facebook api – Download Whatsapp Business Media Image API

I am Using Whatsapp Media API to get Image send from user to business number using webhooks and I also get the Image ID and URL and Image as well in Postman but when I use that curl request made from Postman it always shows Facebook error:

Sorry, something went wrong.
We’re working on it and we’ll get it fixed as soon as we can.

But its working fine in Postman what am I doing wrong?

$ua = 'Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.16 (KHTML, like Gecko)  
Chrome/24.0.1304.0 Safari/537.16';
$curl = curl_init();

curl_setopt_array($curl, array(
  CURLOPT_URL => 'Image_URL_from_Api',
  CURLOPT_USERAGENT => $ua,
  CURLOPT_RETURNTRANSFER => true,
  CURLOPT_ENCODING => '',
  CURLOPT_MAXREDIRS => 10,
  CURLOPT_TIMEOUT => 0,
  CURLOPT_FOLLOWLOCATION => true,
  CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
  CURLOPT_CUSTOMREQUEST => 'GET',
  CURLOPT_SSL_VERIFYPEER => false,
  CURLOPT_HTTPHEADER => array(
    'Authorization: Bearer My_Token'
  ),
));

$response = curl_exec($curl);
curl_close($curl);
echo $response;
