    Part 2: Create an Apple Pay Payment Processing Certificate
    Complete the tasks in this section to create an Apple Pay payment processing
                certificate. Apple Pay servers use this certificate to encrypt payment data.
                Creation of an Apple Pay payment processing certificate consists of two tasks:
- Generating a certificate signing request (CSR).
 - Using the CSR to create an Apple Pay payment processing certificate.
 
IMPORTANT
When you generate a CSR, the sequence of steps you will
                    perform depends on whether you are integrating  decryption and merchant decryption.
