Native UI Integration
We provide native screens to facilitate the integration of payment functions. You can integrate edit shipping info flow to manage shipping info of the order and use our prebuilt payment flow to present payment flow to your shopper.
Edit shipping info flow
Use AWXShippingViewController to allow users to provide a shipping address as well as select a shipping method. The shipping parameter is optional. After successfully saving, it will return a shipping object.
Payment flow
General steps for initiating a one-off payment (guest user checkout) and retrieving the payment result are as follows:
- (Optional) Create a Customer API if you want to save your customer's details and attach payment information to them. (This step is compulsory when you process recurring payment for a new customer)
- Create a Payment Intent API on your server and pass it to your client
- Create a payment session with corresponding payment type and order information
- Present payment flow by passing payment session to Airwallex SDK
- Query and present payment result in callback functions
Integration steps for Redirect module and Card module are the same, they only differ in actions performed by the SDK.
However, when incorporating WeChat Pay module, you need to implement another callback function onResp declared by WeChat SDK to check the payment result which will be invoked when the shopper completes payment in WeChat app and gets redirected back to your app.
For recurring payments, see iOS recurring payments integration guide.
Custom Theme
You can overwrite the color value in your app to customize the theme of SDK pages.
