In-App Transactions Using the

Cybersource

API and Decryption

When the customer chooses to pay with Apple Pay, you use the Apple PassKit Framework to request the encrypted payment data from Apple.

Apple uses the Secure Element to create a

payment token

and encrypt the token’s

payment data

before it sends your application.

You forward the encrypted payment data to your order management system.

Using the

Cybersource

API, you submit the authorization request. In the

paymentInformation.fluidData.value

field, include the Base64-encoded value obtained from the

paymentData

field of the

PKPaymentToken

structure.

Cybersource

decrypts the payment data and forwards the information to the payment network, which includes your processor and the relevant payment card company.
