Installation

1. Install django-oscar-api using the documentation.

2. Install the django-oscar-api-checkout package.:

       'oscarapicheckout',
   ] + get_core_apps([])
   ...
   

4. Configure Oscar's order status pipeline.:

   # myproject/settings.py
   ...
   # Needed by oscarapicheckout
   ORDER_STATUS_PENDING = 'Pending'
   ORDER_STATUS_PAYMENT_DECLINED = 'Payment Declined'
   ORDER_STATUS_AUTHORIZED = 'Authorized'
   
   # Other statuses
   ORDER_STATUS_SHIPPED = 'Shipped'
   ORDER_STATUS_CANCELED = 'Canceled'
   
   # Pipeline Config
   OSCAR_INITIAL_ORDER_STATUS = ORDER_STATUS_PENDING
   OSCARAPI_INITIAL_ORDER_STATUS = ORDER_STATUS_PENDING
   OSCAR_ORDER_STATUS_PIPELINE = {
       ORDER_STATUS_PENDING: (ORDER_STATUS_PAYMENT_DECLINED, ORDER_STATUS_AUTHORIZED, ORDER_STATUS_CANCELED),
       ORDER_STATUS_PAYMENT_DECLINED: (ORDER_STATUS_AUTHORIZED, ORDER_STATUS_CANCELED),
       ORDER_STATUS_AUTHORIZED: (ORDER_STATUS_SHIPPED, ORDER_STATUS_CANCELED),
       ORDER_STATUS_SHIPPED: (),
       ORDER_STATUS_CANCELED: (),
   }
   
   OSCAR_INITIAL_LINE_STATUS = ORDER_STATUS_PENDING
   OSCAR_LINE_STATUS_PIPELINE = {
       ORDER_STATUS_PENDING: (ORDER_STATUS_SHIPPED, ORDER_STATUS_CANCELED),
       ORDER_STATUS_SHIPPED: (),
       ORDER_STATUS_CANCELED: (),
   }
   

5. Configure what payment methods are enabled and who can use them.:

   # myproject/settings.py
   ...
   API_ENABLED_PAYMENT_METHODS = [
       {
           'method': 'oscarapicheckout.methods.Cash',
           'permission': 'oscarapicheckout.permissions.StaffOnly',
       },
       {
           'method': 'some.other.methods.CreditCard',
           'permission': 'oscarapicheckout.permissions.Public',
       },
   ]
   

6. Add oscarapicheckout to your root URL configuration directly before oscarapi.:

   # myproject/urls.py
   ...
   from django.apps import apps
   from oscarapi.app import application as oscar_api
   from oscarapicheckout.app import application as oscar_api_checkout
   
   urlpatterns = patterns('',
       ...
       url(r'^api/', include(apps.get_app_config("oscarapicheckout").urls[0])), # Must be before oscar_api.urls
       url(r'^api/', include(oscar_api.urls)),
       ...
   )
