Totally cool payments abstraction

Every time you need to integrate a payments solution, you have to get used to a new library. That's super annoying. What if there was a single interface that could be configured to use any of the most popular payments solutions? This is an attempt at that. Cool.

To get to know the library, see the examples.

There are basically two different ways of handling payments. This library will strive to eventually support both. We are starting out with the simplest and most-commonly used (per-project, not per-end-user) one: the Checkout model.

In the Checkout Model, the user is sent off the product website to complete their payment at a third party. The thirdt party is hard to get rid off, and using the checkout model saves development time: no longer is there a need to develop the actual checkout window itself.

Known Checkout-Model Payment Methods

• PayPal Express Checkout
• ePay (Danish)
• NETS (Danish)
• Checkout by Amazon

There are some alternatives on this general model. These do not fit directly into the code written for this library:

Stripe Checkout overlays the checkout window on your current website, but still requires you to handle the data.

Gumroad Overlay is basically a bit of javascript which lets them handle all of the hard work.

For big business, you will want complete control over the payment. This model leaves the product website to take care of getting user input. You should not use this model if you don't use encrypted connections, and your site has to be convincing, or customers won't trust you with their credit card information.

Known On-Site Model Payment Methods

• Stripe
• PayPal

This library is not just pre-1.0. It is pre-0.1. Be very cautions (read the code) before using it in production.
