Is it possible the API you are using requires JSON or something else? — dobson, Mar 03 '20 at 11:41
it doesn't requires JSON format .. -F "scenario=http://XXXXXXXXX/api/service/scenarios/3728940075" this URL i have to post to "http://XXXXXXXXX/api/service" uri — Raghu K, Mar 03 '20 at 11:43

I have checked exact request headers and post data sent by your php curl code and curl -F command line. The only difference is that curl -F command line add User-Agent header, and php curl by default does not include any User-Agent.

It is possible that remote server does check UA string and return 400 bad request if empty.

Try to add something like:

curl_setopt($curl, CURLOPT_USERAGENT, 'Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:74.0) Gecko/20100101 Firefox/74.0');

to your php curl code.

$data = http_build_query($postdata);    
$curl = curl_init();
curl_setopt($curl, CURLOPT_VERBOSE, false);
curl_setopt($curl,CURLOPT_HEADER, false); 
curl_setopt($curl, CURLOPT_URL, "http://XXXXXXXXXXXXXX/api/service");
curl_setopt($curl,CURLOPT_POSTFIELDS, $data);
curl_setopt($curl, CURLOPT_FOLLOWLOCATION, true);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true); 
$response = curl_exec($curl);
$err = curl_error($curl);
curl_close($curl);
if ($err) {
    echo "cURL Error #:" . $err;
} else {
    return $response;
