django-shop-viveum 0.1

====================
django-shop-viveum
====================

This module is a payment backend module for django-SHOP (https://github.com/divio/django-shop),
using Viveum (https://viveum.v-psp.com) as the shops payment service provider.
It can be used for credit card and other kind of payments.

Currently only payment methods are implemented, which do not require a PCI DSS
certification (https://www.pcisecuritystandards.org/) for your shop.
This means that your shop never "sees" the credit card numbers, and thus can not
store and/or abuse it.

Installation
============
Using pip::

pip install django-shop-viveum

Viveum Configuration
====================

Get in touch with Viveum and ask for a test account. They will send you an identifier
and a password. Use the given values and log into

Test the Configuration

In order to run the unit tests, you must install an additional Python package,
which is not required for normal operation::

Unfortunately there might be an unresolved issue with SSL on requests. Please read
docs/ssl-problem.rst for details.

Run ``./runtests.sh``.
If everything worked fine, you should receive two emails, one for a successful,
and one for a declined payment.
If there is an error, check the error log at the Viveum admin interface.

If all tests work fine, use these tested settings for your production environment.

* add ``viveum``, to INSTALLED_APPS.
