    var tco = new Twocheckout({
        apiUser: "your_username",                              
        apiPass: "your_password",
        sellerId: 'your_seller_id',                             
        privateKey: "your_private_key",
        demo: true,
        sandbox: true
    });

    var params = {
            "merchantOrderId": "001",
            "token": "gener",
            "currency": "USD",
            "total": "10.00",
            "billingAddr": {
                "name": "Testing Tester",
                "addrLine1": "123 Test St",

                "phoneNumber": "5555555555"
            }
        };
