Braintree Payments Transparent Redirect¶

Braintree Payments Transparent Redirect is a service offered by Braintree Payments to reduce the complexity of PCI compliance.

Note

This integration makes use of the official braintree python package offered by Braintree Payments. Please install it before you use this integration.

Refer to the Braintree Payments Server to Server Gateway for the settings attributes.

Here are the methods and attributes implemented on the BraintreePaymentsIntegration class:

__init__(self, options=None): The constructor method that configures the Braintree environment setting it either to production or sandbox mode based on the value of settings.MERCHANT_TEST_MODE.
service_url(self): A property that provides the URL to which the Transparent Redirect form is submitted.

get_urls(self): The method sets the url to which Braintree redirects after the form submission is successful. This method is generally mapped directly in the urls.py.

from billing import get_integration

braintree = get_integration("braintree_payments")

urlpatterns += patterns('',
   (r'^braintree/', include(braintree.urls)),
)

braintree_notify_handler(self, request): The view method that handles the confirmation of the transaction after successful redirection from Braintree.
braintree_success_handler(self, request, response): If the transaction is successful, the braintree_notify_handler calls the braintree_success_handler which renders the billing/braintree_success.html with the response object. The response object is a standard braintree result described here.
braintree_failure_handler(self, request, response): If the transaction fails, the braintree_notify_handler calls the braintree_failure_handler which renders the billing/braintree_error.html with the response which is a standar braintree error object.
generate_tr_data(self): The method that calculates the tr_data to prevent a form from being tampered post-submission.
generate_form(self): The method that generates and returns the form (present in billing.forms.braintree_payments_form) and populates the initial data with the self.fields (added through either the add_fields or add_field methods) and tr_data.

Example:¶

In the views.py:

braintree_obj = get_integration("braintree_payments")
# Standard braintree fields
fields = {"transaction": {
            "order_id": "some_unique_id",
            "type": "sale",
            "options": {
                "submit_for_settlement": True
              },
            },
            "site": "%s://%s" %("https" if request.is_secure() else "http",
                                RequestSite(request).domain)
         }
braintree_obj.add_fields(fields)
return render_to_response("some_template.html",
                          {"bp": braintree_obj},
                          context_instance=RequestContext(request))

In the urls.py:

braintree_obj = get_integration("braintree_payments")
urlpatterns += patterns('',
   (r'^braintree/', include(braintree.urls)),
)

In the template:

{% load render_integration from billing_tags %}
{% render_integration bp %}
