How to integrate charging a credit card into LabView?

[KWILL]

I need to be able to charge a credit card and verify that the transaction was approved.  I am set up as a Merchant server but do not know how I can use Labview and integrate with a processing company such as PowerPay or Authorize.net to complete the transaction all from a self service kiosk type application.  Any help or direction would be greatly appreciated!  Thanks.

You should look at PowerPay / Authorize.net's API for processing credit card requests - they generally provide an API and/or sample code that you can put into an application.

Generally, I would suspect that this would require a HTTPS POST request - including the required fields as required by the payment gateway. Looking at Chapter 3 of this documents seems to suggest that: http://www.authorize.net/support/CP_guide.pdf

You would then receive a response indicating whether or not the payment was successful.
