CURL > API = no response - php

Question

We're posting from a wordpress form to an API.
Everything we have read so far seems to indicate that this should work.
All CURL config seems to be there and when passing the JSON through Postman, we do get a response.
BUT we do not get a response through this CURL implementation.
Please advise.
add_action( 'wpcf7_before_send_mail', 'CF7_pre_send' );
function CF7_pre_send($cf7) {
$data = array(
"user" => array(

Try this:
$ch = curl_init();
curl_setopt( $ch, CURLOPT_URL, "url-goes-here");
curl_setopt( $ch, CURLOPT_POST, true);
curl_setopt( $ch, CURLOPT_POSTFIELDS, $data_string);
curl_setopt( $ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt( $ch, CURLOPT_HTTPHEADER, array('Content-Type:application/json'));
curl_setopt( $ch, CURLOPT_HEADER, 1);
curl_setopt( $ch, CURLOPT_USERPWD, $username . ":" . $password);
curl_setopt( $ch, CURLOPT_SSL_VERIFYHOST, FALSE );
curl_setopt( $ch, CURLOPT_SSL_VERIFYPEER, FALSE );
$result = curl_exec($ch) ;
if( curl_error( $ch ) )
{
echo "Error occurred " . curl_error( $ch );
}
$httpCode = curl_getinfo($ch, CURLINFO_HTTP_CODE);
if ( $httpCode != 200 )
{
echo "Return code is {$httpCode} \n"
.curl_error($ch);
}
else {
echo "<pre>".htmlspecialchars( $result )."</pre>";
}
var_dump($result);
