Alipay Mini Program

Accept Alipay on your mini program on your shopper’s Android or iOS phone. You can choose to integrate Airwallex mobile SDK that supports multiple payment methods. See checkout experience as below:

  1. The shopper chooses to pay with Alipay in mini program
  2. The shopper reviews transaction details and confirm to pay
  3. The shopper completes the payment
  4. Payment succeeds and the shopper is back to merchant’s mini program

Step 1. Initialize a payment Intent

Create a PaymentIntent object with a request_id, amount, currency and a merchant_order_id from your backend server.

Step 2. Get available payment methods

To be able to display Alipay as an 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 country_code, transaction_currency, 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.

Request:

Response: Render payment methods in items to show all available payment methods to the shopper at checkout page.

Note for available payment methods:

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.

Step 3. Redirect to Alipay App to complete payment

When a shopper selects to pay with Alipay on their Mobile App, call the following API endpoints to get a e-wallet cashier URL, which you can redirect the shopper to Alipay APP to complete payment.

  1. Obtain URL from Airwallex and redirect shopper to Alipay App Request:

  1. 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.

  1. Query the PaymentIntent status (Optional)

You may also query the status of a payment anytime via the PaymentIntents API.
