Basic Backend Definition

Default arguments

• captured: Default: True, if False enable preauth
• time_reserve: Default: timedelta(seconds=0), how many time should a used token have left at least?

Extra

Extra should not affect Provider, it is only for the integration. Notable exception is name: name is used for provider_factory caching

Rational behind this is that providers of the same type but different parameters can exist.

name is set to dictionary key name in django, testcommon and defaults to Provider Class Name

Builtin backends

See web_payments_dummy package and web_payments_externalpayments package

Writing a backend

See testcommon and externalpayments for good examples.

Test project

For developing a backend a test project exists. It’s located in web_payments_dummy/django_dummy.

1. Example: run server:

   .. code-block:: bash
   ./web_payments_dummy/django_dummy/manage.py runserver
   

Adding your own backends can be done with the DJANGO_SETTINGS_MODULE environment variable and point to your own settings. Own settings can live in the settings folder (gitignored) and inherit from web_payments_dummy.django_dummy.settings (for defaults)
