from decimal import Decimal as D
from oscar_sagepay import facade

tx_id = facade.authenticate(amount, currency, bankcard, shipping_address, 
                            billing_address, description, order_number)

where:

• amount is a decimal.Decimal instance
• currency is the 3 character currency code
• bankcard is an oscar.apps.payment.models.Bankcard instance
