  <p>and here my Code</p>
  
  <pre><code>use GuzzleHttp\Client;
  
   $client =new Client();
  
       $client-&gt;post($url,[
              'form_params' =&gt; [
                '{}'
              ]
          ]);
  </code></pre>
  
  <p>with <code>POSTMAN</code>, I don't need to set <code>Header</code> and  all i need to send <code>{}</code>.</p>
  
  <p>Get this Error : </p>
  
  <pre><code>Client error: `POST http://URL` resulted in a `400 
  Bad Request` response: {"error":"Failed when parsing body as json"}
  </code></pre>
