  // 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. 

  final http = CkHttp();

  http.basicAuth = true;
  http.login = 'API_USERNAME';
  http.password = 'API_PASSWORD';

  final url = 'https://<site>.cardconnect.com:<port>/cardconnect/rest/';

  final String responseStr;
  try {
    responseStr = http.quickGetStr(url);
  } on ChilkatException catch (e) {
    print(e.lastErrorText);
    return;
  }

  // If we get a 200 response status and an HTML response saying "CardConnect REST Servlet", then our credentials are correct.
  print('response status code = ${http.lastStatus}');

  print('response string:');
  print(responseStr);

  // Sample output:

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