Is there a tutorial somewhere showing the code on how to correctly void a transaction using the AIM method. I downloaded the csharp_aim package and that was of little help. I was reading through the AIM_guide.pdf and it states that the card number and exp. date are required for transactions. First of all, I don't have access to the card number and exp. date when I am voiding in my code. Second, from the posts I've seen in this forum, it doesn't look like others are providing that info for voids so I hope I don't have to.
