This project contains a pure Python implementation of the ACI Worldwide Payment Gateway that is used by many payment gateway providers.

Usually, the implementation kit comes with a few reference implementations of the payment gateway, but they are only available as a Java class, or a .dll library.

So this python class was created for those of us that do not use Java or ASP.NET/.dlls for their development.

The library has successfully been used in production.

UPDATE - 2011-12-28

 A __*major*__ update and overhaul has been done, and a new
 branch production has been created.

  from e24PaymentPipe import e24PaymentPipe as gw
  g = gw('/some/path/to/somefile.cgn','somealias')
  try:
    g.parse()
  except zipfile.BadZipfile:
  except AliasNotFound:
    pass

  # Before you try a transaction,
  # you have to set the error and response URLs

  g.ERROR_URL = 'https://www.example.com/error.html'
  g.RESPONSE_URL = 'https://www.example.com/response.jsp'

  trackid = 12343
  try:
     r = g.transaction(trackid,amount)
  except e:
     print e

  print('Payment ID: %s' % r[0])
  print('Payment URL: %s' % r[1])
