Integration Options
National Australia Bank
supports Apple Pay in multiple integration options. Three of
the most widely used options are VDC NAB
decryption, merchant
decryption, and Checkout API
. Each option presents specific tradeoffs
and advantages, and you can select the integration model that best fits your
business.Apple Pay integration is built into the
National Australia Bank
payment management
platform. National Australia Bank
offers two integration methods for handling the
payment data returned by the Apple Pay service for processing payments. In response to
an authorization request, Apple Pay returns payment data in an encrypted payload. The
encrypted payment data is handled and processed differently, depending on which
integration method is used. Both decryption methods support Apple Pay in-app and Apple
Pay on the web.VDC NAB
Decryption
VDC NAB
DecryptionFor
VDC NAB
decryption,
you implement Apple Pay directly on your checkout page.
You send National Australia Bank
all encrypted payment information that
you receive from Apple Pay.
VDC NAB
creates and manages the Apple Pay decryption keys,
extracts and decrypts payment information, and
maps the information to the appropriate fields for authorization and other payment services
on your behalf.
Having
VDC NAB
process your Apple Pay transactions
reduces your exposure to sensitive payment information.Merchant Decryption
For merchant decryption, you (the merchant or the integrator)
manage all aspects of the Apple Pay implementation,
from generation of the payment encryption keys to
decryption of the payment response payload from Apple Pay.
As a merchant, you submit the Apple Pay payment token and
other payment information to
VDC NAB
for processing.
With merchant decryption,
payment instrument details remain visible to you, and
you control the technical development that decrypts this information.Unified Checkout Integration
