See more REST Examples

Demonstrates how to use a client certificate with a REST connection where the certificate and private key are located on a USB token or smart card.

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

// This example shows how to use the Chilkat socket object's connection.
Chilkat.Rest rest = new Chilkat.Rest();
Chilkat.Socket socket = new Chilkat.Socket();

// Set the certificate to be used for mutual TLS authentication
Chilkat.Cert cert = new Chilkat.Cert();

// If the smartcard or token requires a PIN...
cert.SmartCardPin = "000000";

bool success = cert.LoadFromSmartcard("");
if (success != true) {
    Debug.WriteLine(cert.LastErrorText);
    return;
}

success = socket.SetSslClientCert(cert);
if (success != true) {
    Debug.WriteLine(socket.LastErrorText);
    return;
}

// Establish the connection using the socket object (with client certificate authentication).
bool bTls = true;
int port = 443;
int maxWaitMs = 5000;
success = socket.Connect("www.example.com",port,bTls,maxWaitMs);
if (success != true) {
    Debug.WriteLine("Connect Failure Error Code: " + Convert.ToString(socket.ConnectFailReason));

bool bAutoReconnect = true;

// Use the connection:
success = rest.UseConnection(socket,bAutoReconnect);
if (success != true) {
    Debug.WriteLine(rest.LastErrorText);
    return;
}

// At this point we are connected and can make REST calls...
// For example..
string responseJson = rest.FullRequestNoBody("GET","/someQuery");
