Handle response result

There is an event that is raised when a response is received from the Traditional myPOS device on a particular request. You should subscribe to the event to get the response result and any response data that is received.

1. Define an event handler method

       protected void ProcessResult(ProcessingResult r)
       {
	       // handle the response here
            if (r.TranData != null)
            {
		          // transaction response
            }
 		   }
       

2. Attach your event handler to the event:

   public Form1()
    {
         InitializeComponent();

         terminal.ProcessingFinished += ProcessResult;
    }

Make a payment

Once initialization and connection to the terminal is completed, you can start using the myPOS Terminal .Net SDK to accept card payments.

RequestResult r = terminal.Purchase(Amount, cur, txtReference.Text);

Transaction reference is an optional parameter and can be empty or NULL.

Make a Refund

You can initiate a refund transaction to the customer’s card account with the specified amount.

RequestResult r = terminal.Refund(Amount, cur, txtReference.Text);

Transaction reference is an optional parameter and can be empty or NULL.

Make a Pre-authorization

You can initiate a pre-authorization transaction and lock funds from the customer’s card account with the specified amount.

RequestResult r = t.Preauthorization(Amount, cur, txtReference.Text);

Transaction reference is an optional parameter and can be empty or NULL.

Make a Pre-authorization Completion

You can complete a pre-authorization transaction with the customer’s card account with the specified completion amount.

RequestResult r = t.CompletePreauth(strPreauthCode, Amount);

For strPreauthCode you need to use the pre-authorization code of the original pre-authorization transaction.

For Amount, select the amount which you want to take from the client. It can not be a greater number than the Pre-authorized amount from the original transaction.

Make a Pre-authorization Cancellation

You can initiate a cancellation for a pre-authorization transaction.

RequestResult r = t.CancelPreauth(strPreauthCode);

For strPreauthCode you need to use the pre-authorization code of the original pre-authorization transaction.

Reprint last receipt

With this method the host application could request reprint of the last transaction slip.

RequestResult r = terminal.ReprintReceipt();

Custom receipt print

You can print receipt with your custom data using the following delimiters:

\ - symbol 
\n – new line \L – prints logo \l – left alignment \c - center alignment \r - right alignment \W – double width \w – normal width \H – double height \h – normal height

terminal.PrintExternal(txtPrintData.Text);
