What is the Simplest Possible Payment Gateway to Implement? (using Django)

Question

I'm developing a web application that will require users to either make one time deposits of money into their account, or allow users to sign up for recurring billing each month for a certain amount of money.

I've been looking at various payment gateways, but most (if not all) of them seem complex and difficult to get working. I also see no real active Django projects which offer simple views for making payments.

Ideally, I'd like to use something like Amazon FPS, so that I can see online transaction logs, refund money, etc., but I'm open to other things.

I just want the EASIEST possible payment gateway to integrate with my site. I'm not looking for anything fancy, whatever does the job, and requires < 10 hours to get working from start to finish would be perfect.

I'll give answer points to whoever can point out a good one. Thanks!

EDIT: This is to accept payments in the US only. I don't need an international payment gateway. And it only needs to support US English.

Answer 1

Authorize.net is pretty simple, this question suggested a few Django apps that are at least started: http://stackoverflow.com/questions/1637902/python-django-which-authorize-net-library-should-i-use

Answer 2

I've done successful integrations for both Google Checkout and PayPal ExpressCheckout in Django. Both services have stable, well-developed APIs, and neither one was too difficult to implement. There are good Python libraries already written to do the heavy lifting for you, too.

Answer 3

Braintree is about to release a Python client library that could give you the quick integration that you're looking for. Here are the tests for the Transaction class to give you an idea of what it's like: http://pastie.org/private/qdb4q5db3328gpp4apaw8w . We're planning to release it on Friday.

Answer 4

You may check Django payments app Mamona which I started not so long time ago. It currently handles PayPal only. It doesn't support refunds and recurring payments yet, but is very simple and can be attached to any other application without changing it's code.
