Thanks, I got it varified. One more issue I have. I am creating a groupon.com like site, with group buying service. Here, users are only subscribed to a product, they do not buy live. We set up a minimum number of people required to make this deal successful. At the time of subscription, users enter their credit card, and I have to authorize it, but do not charge. Now, if I get enough number of buyers, I will charge all of them. I was suggested to use website payment pro for this application, but not sure. Any idea which method I should use? I will need to accept credit cards from all over the world, but seller account is in US.
