Hello, 
I am not able to get a Jason response from the end point. http://largesystems.phpwebhosting.com/WQTDev/sf_get_bom.php?quotenum=21660
The only response I am getting back is 
09:40:02:478 USER_DEBUG [20]|DEBUG|System.HttpResponse[Status=OK, StatusCode=200]

However, if I copy/paste the code in the browser address I get a response.

Below is the simple code: 

 

public class WQTResponse 
{
  public static void Execute()
    {

        string baseURL ='http://largesystems.phpwebhosting.com/WQTDev/sf_get_bom.php?quotenum=21660';
        
        Http http = new Http();
        HttpRequest request = new HttpRequest();
        request.setMethod('GET');
        request.setHeader('Accept', 'application/json');
        request.setHeader('Content-Type','application/json');
        
        request.setEndpoint(baseURL);
        
        HttpResponse response = http.send(request);
        
        system.debug(response);
        
        //return(response.getBody());
    }
}

Not sure what I am missing
