A couple of questions concerning 2Checkout

Hi all.
I'm trying to integrate 2Checkout with my site to give users another option to make payment.
I just have a couple of questions:
1. How does a customer cancel their subscription? Is it similar to when they use PayPal and there is a 'Cancel' link in member.php that directs the user to PayPal?
2. Do I have to manually process each order? Or is the user able to access the site straight after they have made payment through 2Checkout?
Any help would be greatly appreciated.
