I am busy working on a subscription site and am in need of some help. I don't have a merchant account and therefore cannot take credit cards directly. I see paypal has a service for $20 a month that allows you to take credit cards. I'm confused as to how I would integrate this into my site's subscriptions. How do I make sure they paid before updating their subscription status in the database? I'd like for it to be automatic as opposed to me doing it manually. Does anyone have experience with this that can explain to me how they went about the process? Doesn't have to have anything to do with Paypal.
