Mobile Website Browser
Accept Alipay HK on your mobile website by redirecting shoppers to Alipay HK Cashier. See checkout experience as below
- The shopper chooses to pay with Alipay HK and proceed payment with mobile browser
- The shopper login to Alipay HK account in browser and completes the payment
- Payment succeeds and the shopper is redirected back to the page you designated
Create a PaymentIntent object with a
currency and a
merchant_order_id from your backend server.
To be able to display AlipayHK as a payment option on your checkout page, you need to get available payment methods from Airwallex API.
When the PaymentIntent is created, send a
GET request with parameters
transaction_mode to API endpoint
/api/v1/pa/config/payment_method_types to query for a list of available payment method based on the information provided. The response will also contain the required fields and necessary resources of each payment method for you to display them on your page.
Response: Render payment methods in
items to show all available payment methods to the shopper at checkout page.
Alternatively, you can maintain available payment methods and corresponding resources locally on your server if you do not want to use this API endpoint. However, we highly recommend you get available payment methods dynamically from this API to avoid any trouble when payment method information or resources get updated.
When a shopper selects to pay with Alipay HK on their mobile browser, call the following API endpoints to get a e-wallet cashier URL, which you can redirect the shopper to Alipay HK cashier to complete payment.
- Obtain URL from Airwallex and redirect shopper to Alipay HK cashier
- Wait for notification from Airwallex
Airwallex will notify you on the payment result asynchronously via the webhook API. Please refer to webhook documentation to set up your webhook accordingly. Although subscribing to different events is optional, it is recommended to at least subscribe to the ‘payment_intent.succeeded’ which indicates that the shopper has successfully paid for the order via Alipay HK.
- Query the PaymentIntent status
You may also query the status of a payment anytime via the PaymentIntents API
If you use the mobile browser flow in your App, please do add a referer when you request AlipayHK payment via the url we returned to you. If not, you cannot pull up AlipayHK App successfully.
