Use your own certificate

1. Create a developer account on Apple Pay developer portal. Ensure you have an active email address linked to the account to be able to receive notifications on certificate expiry.
2. Enable Apple Pay payment method for the merchant account at Airwallex. You are not required to add additional domain information on the Airwallex web app when using your own certificate.
3. Create a merchant identifier on the Apple Pay developer portal, which uniquely identifies you as a Apple Pay merchant. Note that this merchant id never expires.
4. Create a payment processing certificate that will be used to encrypt the payment token returned from the Apple Server. This certificate is linked to the merchant identifier created in Step 3. This step requires creation of Certificate Signing Request (CSR), covered in the above link, post which a certificate will be issued by Apple.
5. (Optional) Enable Apple Pay on the developer portal for your mobile application. This step is optional and required only if you would like to support mobile applications. It is not required if you wish to process web-based transactions only.
6. Validate your merchant domain so that a secure connection can be established between your domain and the Apple servers.
7. Create a merchant identity certificate that will enable you to request a Apple Pay payment session . Ensure you select the merchant identifier created in Step #3 while creating a merchant identity certificate. You will also be required to generate a CSR file to be able to receive a merchant identity certificate.

Create a PaymentIntent using the Airwallex API API. This step lists the available payment methods for the merchant account, and should ideally return Apple Pay as an available payment method.

Request Payment session for each Apple Pay transaction and complete merchant validation using the output received from the Payment session response.

Decrypt the payment data using the payment processing certificate based on the event OnPaymentAuthorized

Confirm the PaymentIntent using the Airwallex API API using the decrypted payment token information.
