Google Checkout

Google Checkout is an online payment processing solution provided by Google. The API docs for Google Checkout are available here.

After a transaction, Google Checkout sends a mail to the subscriber, updates the Merchant Center dashboard and pings the merchant at the Notification URL. The HTTP POST data is stored in the GCResponse model instance that can be viewed from the django admin.

The setting attributes required for this integration are:

• MERCHANT_ID: The merchant id assigned by Google after signing up for the service.
• MERCHANT_KEY: A secret key assigned by Google after signing up for the service.

Settings attributes:

MERCHANT_TEST_MODE = True # Toggle for live
MERCHANT_SETTINGS = {
    "google_checkout": {
        "MERCHANT_ID": "???",
        "MERCHANT_KEY": "???"
    }
    ...
}

Example

In urls.py:

gc = get_integration("google_checkout")
urlpatterns += patterns('',
  (r'^gc/', include(gc.urls)),
  # You'll have to register /gc/gc-notify-handler/ in the
  # WorldPay admin dashboard for the notification URL
)

In views.py:

>>> from billing import get_integration
>>> gc = get_integration("google_checkout")
>>> gc.add_fields({'items': [{
...    "amount": 100,
...    "name": "Name of the Item",
...    "description": "Item's description",
...    "currency": "USD",
...    "id": "item_id",
...    "quantity": 1},
...    ....
... ],
... "return_url": "http://example.com/return/", })
>>> return render_to_response("some_template.html",
...                           {"obj": gc},
...                           context_instance=RequestContext(request))

In some_template.html:

{% load google_checkout from google_checkout_tags %}
{% google_checkout obj %}

Template renders to something like below:
