// This example assumes the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

Chilkat.Http http = new Chilkat.Http();
bool success;

http.BasicAuth = true;
http.Login = "API_USERNAME";
http.Password = "API_PASSWORD";

// Build and send the following JSON:

// The "retref" is the value returned in the JSON response for the Authorization request.

// {
//     "retref":"112989260941",
//     "merchid":"MERCHANT_ID"
// }

Chilkat.JsonObject json = new Chilkat.JsonObject();
json.UpdateString("retref","112989260941");
json.UpdateString("merchid","MERCHANT_ID");

string url = "https://<site>.cardconnect.com:<port>/cardconnect/rest/void";
string responseStr = http.PutText(url,json.Emit(),"utf-8","application/json",false,false);
if (http.LastMethodSuccess == false) {
    Debug.WriteLine(http.LastErrorText);
    return;
}

// A response status of 200 indicates potential success.  The JSON response body
// must be examined to determine if it was truly successful or an error.
Debug.WriteLine("response status code = " + Convert.ToString(http.LastStatus));

Chilkat.JsonObject jsonResp = new Chilkat.JsonObject();
jsonResp.Load(responseStr);
jsonResp.EmitCompact = false;

Debug.WriteLine("response JSON:");
Debug.WriteLine(jsonResp.Emit());

// A successful response looks like this:

// {
//   "authcode": "REVERS",
//   "respproc": "FNOR",
//   "amount": "0.00",
//   "resptext": "Approval",
//   "currency": "USD",
