CURL PHP Object reference not set to an instance of an object

I have to make a POST request to a third party API. I'm doing it through CURL, I've been trying for days but I can't get a positive return. Could anyone evaluate if my code is right? I tested the API in Insomnia and I'm getting feedback, but in php I can only get that feedback.

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POSTFIELDS, $body);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Authorization: '.$authorization, 'Content-Type: application/json'));
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

$result = curl_exec($ch);
$resu = (array) json_decode($output);
echo '<pre>';
var_dump($result);
echo '</pre>';

Return on variable $ return

string(4406) "{"ClassName":"System.NullReferenceException","Message":"Object reference not set to an instance of an object.","Data":null,"InnerException":null,"HelpURL":null,"StackTraceString":" at Wangkanai.Detection.Collections.InternetExplorer..ctor(String agent)\r\n at Wangkanai.Detection.BrowserResolver.GetBrowser()\r\n

Solucion:

curl_setopt($ch, CURLOPT_USERAGENT , "'Mozilla/5.0 (Windows NT 6.2; WOW64)  AppleWebKit/537.31 (KHTML, like Gecko) Chrome/26.0.1410.64 Safari/537.31'");

Make sure you know where to use $resu and $result. – u_mulder
$resu return is NULL. I was just testing – Renata Macedo
What HTTP status code are you seeing in the response? I have a feeling something maybe wrong in $body but there is no way of knowing for sure. The status response should tell you where the problem lies. – Alex Barker
The feedback I get is that informed in the question. And $body is a json written as a string. – Renata Macedo
