AlipayHK Component

Add AlipayHK to an existing Components integration.

Our AlipayHK Component renders AlipayHK in your payment form. When making an AlipayHK payment, you additionally need to use createFromAction to handle the redirect to AlipayHK and back to your website.

Before you begin

This page explains how to add AlipayHK to your existing Web Components integration. The Web Components integration works the same way for all payment methods. If you haven't done this integration yet, refer to our Components integration guide.

Before starting your AlipayHK integration:

Make sure that you have set up your back end implementation, and created an instance of AdyenCheckout.
Add AlipayHK in your test Customer Area.

Show AlipayHK in your payment form

To show AlipayHK in your payment form, you need to:

From your server, make a /paymentMethods request specifying:
- countryCode: HK
- amount.currency: HKD
Pass the full response to the paymentMethodsResponse object when creating an instance of the AdyenCheckout.
Add the AlipayHK Component:
a. Create a DOM element for AlipayHK, placing it where you want the form to be rendered:
```
<div id="alipayhk-container"></div>
```
b. Create an instance of the AlipayHK Component, and mount it.
```
 const alipayhk = checkout.create('alipay_hk').mount('#alipayhk-container');
```

Make a payment

When the shopper selects to pay, the Component calls the onChange event, which contains a state.data.

If state.isValid is true, collect the state.data and pass this to your server.

From your server, make a /payments, specifying:

paymentMethod: The state.data.paymentMethod from the onChange event from your front end.

}).then(res => res);

The /payments response contains:

action: Object containing information about the redirect.
action.paymentData: Store this on your server — you need to submit this in your /payments/details request when handling the redirect.
action.method: GET or POST. The HTTP request method that you should use. After the shopper completes the payment, they will be redirected back to your returnURL using the same method.
The redirect method depends on your payment method configuration and the length of the data included in the request, so make sure that your integration can handle both HTTP GET and HTTP POST methods.

/payments response

{
"resultCode": "RedirectShopper",
 "action": {
   "method": "GET",
   "paymentData": "Ab02b4c0!BQABAgCSZT7t...",
   "paymentMethodType": "alipay_hk",
   "type": "redirect",
   "url": "https://test.adyen.com/hpp/redirect.shtml?brandCode=.."
},
"details": [
  {
      "key": "payload",
      "type": "text"
  }
],
...
}

Pass the action object to your front end.

Handle the redirect result

Call createFromAction and pass the action object from the previous step. This will return a new Component that you need to mount:
```
   checkout.createFromAction(action).mount('#my-container');
```
The Component redirects the shopper to AlipayHK's website where they scan a QR code and complete the payment.
After the shopper is redirected back to your website, check the payment result by making a /payments/details request, specifying:
- paymentData: Value you received in the /payments response.
- details: Object that contains the URL-decoded values of the parameters that were returned when the shopper was redirected back to your site. For example, payload. To check the parameters that you should submit, refer to the details.key returned in the /payments response.
https://docs.adyen.com/payment-methods/online-banking-india/web-component#-payments-details-request
- /payments/details request
{ "paymentData":"Ab02b4c0!BQABAgCJN1wRZuGJmq8dMncmypvknj9s7l5Tj...", "details":{ "{hint:Verify the parameters from /payments response}payload{/hint}":"Ab02b4c0!BQABAgCW5sxB4e/==" } }
You receive a response containing:
- resultCode: Use this to present the result to your shopper.
- pspReference: Our unique identifier for the transaction.
https://docs.adyen.com/payment-methods/online-banking-india/web-component#-payments-details-response
- /payments/details response
{ "resultCode": "Authorised", "pspReference": "88154795347618C" }

For more information and detailed instructions, refer to Handling the redirect result.

Present the payment result

Use the resultCode that you received in the /payments/details response to present the payment result to your shopper.

The resultCode values you can receive for AlipayHK are:

resultCode	Description	Action to take
Authorised	The payment was successful.	Inform the shopper that the payment has been successful. You will receive the funds in 3 days.
Cancelled	The shopper canceled the payment while on the Alipay website.	Ask the shopper whether if they want to continue with the order, or ask them to select a different payment method.
Pending or Received	The shopper has completed the payment but the final result is not yet known.	Inform the shopper that you've received their order, and are waiting for the payment to be completed. To know the final result of the payment, wait for the AUTHORISATION notification.
Refused	The payment was refused by the shopper's bank.	Ask the shopper to try the payment again using a different payment method.

If a shopper completed the payment but failed to return to your website or app, you will receive the outcome of the payment in an AUTHORISATION notification.
