Are there any good tutorials on how to connect paypal to activemerchant? Rails cast episode is very old and I need something for Rails 4. And another problem, in rails cast, they initiate the gateway in the initializer. But in the activemerchant documentation they initiate it in right before the payment. I think it’s in the controller. What is the right and secure way to do it?
PS : I need people to go to PAYPAL and make the payments either by giving credit card or through paypal account.
