Apple Pay
This guide describes how to add Apple Pay to your Airwallex iOS SDK integration.
Step 1: (Optional) Create a Customer
Create a Customer object and pass it to your server if you want to save your customer's details and attach payment information to this object. (This step is compulsory when you process recurring payments for a new customer)
From your server, access Airwallex API to Create a Customer API
Step 2: Create a PaymentIntent
Your client app will need a PaymentIntent to form a payment session for Airwallex SDK to present a payment flow.
From your server, access Airwallex API to Create a PaymentIntent API and pass the returned PaymentIntent to the client app.
Step 3: Create a PaymentSession
Create a PaymentSession with all the order related information and payment type information. Ensure you include the merchant Identifier information received after registering on Apple developer portal, see Enable Apple Pay for iOS
Step 4: Present payment flow to the shopper
Call AirwallexStarter.presentPaymentFlow with an AirwallexSession and a PaymentResultListener to present payment flow to the shopper.
Step 5: Handle the response
In PaymentResultListener, handle the payment status which shows whether the shopper has completed the payment flow or not.
Note that a completed flow does NOT imply a successful transaction, you will need to query the payment result afterwards through your server to know whether the order is paid or not. Inside AWXPaymentResultDelegate, ask your server to retrieve the PaymentIntent.
From your server, retrieve the PaymentIntent API, get the payment result and return it to the client app.
