Requirements

Requirement	Description
Integration type	Make sure that you have an existing API-only integration.
Setup steps	Before you begin, add AlipayHK in your test Customer Area.

Include AlipayHK in the list of available payment methods. You do not need to collect any information from the shopper in your payment form.

We provide logos for AlipayHK which you can use on your payment form. For more information, refer to Downloading logos.

If you are using the /paymentMethods to show available payment methods to the shopper, specify the following:

The response contains paymentMethod.type: alipay_hk.

In your /payments request, specify:

In the /payments response, note the action object. This contains the information needed to redirect the shopper.

To complete the payment, redirect the shopper to the action.url returned in the /payments response, taking into account the following recommendations:
- When using the HTTP GET method:
  For security reasons, when showing the redirect in the app, we recommend that you use SFSafariViewController for iOS or Chrome Custom Tabs for Android, instead of WebView objects. Also refer to the security best practices for WebView.
- Redirection for mobile integrations:
  For mobile integrations, we strongly recommended that you redirect the shopper to the default browser of their device. Redirecting to the default browser ensures the best compatibility, handling of multi-factor authentication, app-to-app redirection, and error handling.
After the shopper is redirected back to your website, check the payment result by making a POST /payments/details request, specifying:
- details: object that contains the URL-decoded redirectResult returned when the shopper was redirected back to your site.
In the response note the following:
- resultCode: use this to present the result to your shopper.
- pspReference: our unique identifier for the transaction.

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:

Authorised	The payment was successful.	Inform the shopper that the payment has been successful. You will receive the funds in 3 days.
