Http h = new Http();

// Instantiate a new HTTP request, specify the method (GET) as well as the endpoint  
    String url='http://tools.xxxxxxx.com/xxxxx/xxxx.php';
    HttpRequest req = new HttpRequest();
    req.setEndpoint(url);
    req.setMethod(url);

// Send the request, and return a response  
    
    HttpResponse res = h.send(req);
    String str=res.getBody();

Find below a sample working code of Http request :

 

Http h = new Http();

HttpRequest req = new HttpRequest();

String url = 'https://api-3t.sandbox.paypal.com/2.0/';

String doRequest;

doRequest =  '<soap:Envelope xmlns:soap=' + '\'' + 'http://schemas.xmlsoap.org/soap/envelope/'  + '\'' + ' xmlns:xsi=' + '\''+ 'http://www.w3.org/2001/XMLSchema-instance'  + '\'' + ' xmlns:xsd=' + '\''+ 'http://www.w3.org/2001/XMLSchema' + '\'' + '></soap:Envelope>';

 req.setBody(doRequest);

req.setEndpoint(url);

req.setMethod('POST');

req.setHeader('Content-length', '1753' );

req.setHeader('Content-Type', 'text/xml;charset=UTF-8');

req.setHeader('SOAPAction','');

req.setHeader('Host','api-aa.sandbox.paypal.com');

HttpResponse res = h.send(req);

String xml = res.getBody();

rawResponse = xml;

 

Hope this helps.

the HTTP request itself is working now but the issue is the with the trigger itself  this code is running  in trigger on opportunity update and inside this code am updating the opportuninty so am getting this error... so do you know what does it mean?
