I was looking through the docs of Paypal and Amazon and their Payment APIs are very complicated. Is there any simple and cheap payment solutions out there like Braintree where I can just integrate their API seamlessly into my rails app?<p>(Braintree requires me to talk to their sales representative and I don't know how that will turn out).
