An extension on top of django-oscar-api providing a more flexible checkout API with a pluggable payment methods interface.

Compatible Payment Plugins

  • django-oscar-cybersource: Provides order payment using Cybersource Secure Acceptance Silent Order POST for PCI SAQ A-EP compliant credit card processing.

Installation

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

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

    $ pip install django-oscar-api-checkout
  3. Add oscarapicheckout to your INSTALLED_APPS:

    # myproject/settings.py
    ...
    INSTALLED_APPS = [
        ...
        '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 oscarapi.app import application as oscar_api
    from oscarapicheckout.app import application as oscar_api_checkout
    
    urlpatterns = patterns('',
        ...
        url(r'^api/', include(oscar_api_checkout.urls)), # Must be before oscar_api.urls
        url(r'^api/', include(oscar_api.urls)),
        ...
    )

Usage

These are the basic steps to add an item to the basket and checkout using the API.

  1. Add an item to the basket.:

    POST /api/basket/add-product/
    
    {
        "url": "/api/products/1/",
        "quantity": 1
    }
  2. List the payment methods available to the current user.:

    GET /api/checkout/payment-methods/
  3. Submit the order, specifying which payment method(s) to use.:

    POST /api/checkout/
    
    {
        "guest_email": "joe@example.com",
        "basket": "/api/baskets/1/",
        "shipping_address": {
            "first_name": "Joe",
            "last_name": "Schmoe",
            "line1": "234 5th Ave",
            "line4": "Manhattan",
            "postcode": "10001",
            "state": "NY",
            "country": "/api/countries/US/",
            "phone_number": "+1 (717) 467-1111",
        },
        "billing_address": {
            "first_name": "Joe",
            "last_name": "Schmoe",
            "line1": "234 5th Ave",
            "line4": "Manhattan",
            "postcode": "10001",
            "state": "NY",
            "country": "/api/countries/US/",
            "phone_number": "+1 (717) 467-1111",
        },
        "payment": {
            "cash": {
                "enabled": true,
                "amount": "10.00",
            },
            "creditcard": {
                "enabled": true,
                "pay_balance": true,
            }
        }
    }
  4. Check the status of each enabled payment option.:

    GET /api/checkout/payment-states/

Changelog

0.2.3

  • Make the order in which signals are sent during checkout consistent for synchronous and asynchronous payment methods.
    • Previously a synchronous payment method resulted in sending order_payment_authorized before sending order_placed, but an asynchronous payment method would trigger order_placed first followed by order_payment_authorized (on a subsequent HTTP request). They are still different in terms of synchronous payment methods firing both signals on the same request and asynchronous payment methods triggering them on different request, but at least now they are always fired in the same order: order_placed first followed by order_payment_authorized.
