Logging

IN DEVELOPMENT

Automatic Logging

Automatic logging is included. It can be enabled by adding the appropriate AppSettings keys:

• Cardknox.Logging: enabled
• Cardknox.LogLocation: ~/App_Data/Log/cardknox_{0:MMddyyyy}.log

The Cardknox.LogLocation key can be app-specific by prepending the ~ character or it can be absolute by omitting it.

• Cardknox.LogLocation: /var/log/cardknox/{0:MMddyyyy}.log
• Cardknox.LogLocation: C:\Temp\Cardknox\{0:MMddyyyy}.log

If installing from NuGet, the System.Configuration.ConfigurationManager package will be added automatically. If installing from source or from the GitHub release, you'll need to install this package yourself.

The sensitive card information (xCardNum, xCVV, xExp, xMagStripe, etc) will not be included for PCI compliance reasons.

Custom Logging

It is possible, beginning in 3.0.2-beta, to implement your own custom logging through the use of the RequestStarted and RequestCompleted event handlers. Using either of these will override and replace the internal logging for whichever event is implemented. Implementing both of these events, it will not be necessary to add the keys to the AppSettings.

When implemented, it will look similar to the following:

using CardknoxApi;
using CardknoxApi.Operations;

public static void Main()
{
    Cardknox c = new Cardknox(new CardknoxRequest("", "", ""));
    c.RequestStarted += C_RequestStarted;
    c.RequestCompleted += C_RequestCompleted;
    CardknoxResponse resp = c.CCRefund(new CCRefund());
}

private void C_RequestStarted(object sender, CardknoxEventArgs e)
{
    // .. custom logging to file or database
}

private void C_RequestCompleted(object sender, CardknoxEventArgs e)
{
    // .. custom logging to file or database
}

CardknoxEventArgs contains the property Results which is a ReadOnlyDictionary<string, string> and is a copy of the data sent to/received from the Cardknox API. The sensitive card information (xCardNum, xCVV, xExp, xMagStripe, etc) will not be included for PCI compliance reasons.
