Ruby on Rails 4 and Stripe

Using stripe can be a much better alternative then using paypal because the user does not get sent anywhere when making their purchase. Another great thing about stripe is how basic there setup is and how easy it integrates into your rails application. There is a super cool testing environment that works by just placing the api in the intializer.

You can use the test api and it reacts the exact same way that the live one does. If you have not learned ruby on rails yet, then you should check out Mattan's class. It goes over the basics to get you started. After you have completed that course, I recommend to go to Ryan Bates tutorial on integrating stripe.
