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

// The CardConnect REST Web Service base URL includes a protocol, host, port and servlet specification.
// 
// For example:
// https://<site>.cardconnect.com:<port>/cardconnect/rest/
// 
// This represents an HTTPS request to the REST web service base URL. 
// The servlet name is fixed within the application; the host and port are assigned by CardConnect. 

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

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

string url = "https://<site>.cardconnect.com:<port>/cardconnect/rest/";
string responseStr = http.QuickGetStr(url);

if (http.LastMethodSuccess == false) {
    Debug.WriteLine(http.LastErrorText);
    return;
}

// If we get a 200 response status and an HTML response saying "CardConnect REST Servlet", then our credentials are correct.
Debug.WriteLine("response status code = " + Convert.ToString(http.LastStatus));

Debug.WriteLine("response string:");
Debug.WriteLine(responseStr);

// Sample output:

// response status code = 200
// response string:
// <html lang="en"><body><h1>CardConnect REST Servlet</h1></body></html
