Hosted Payment Page
The Hosted Payment Page integration option redirects your shoppers to a secure, pre-built payment page hosted by Airwallex. It lets you accept multiple payment methods with a single integration. You do not have to worry about collecting or storing shopper’s payment details as Airwallex fully handles the payment processing thereby significantly reducing your PCI-DSS compliance costs.
Key features include:
- Reduces friction for card payments with input validation, styling and error handling.
- Responsive design to fit seamlessly on any screen size
- Custom styling rules so you can match the look and feel of your site
- Reduced PCI-DSS compliance handling costs – a PCI-DSS SAQ A is sufficient
How it works
The diagram below depicts the information flow in a Hosted Payment Page integration.
Before you begin
Before you implement the integration, consider the following:
Contact your Airwallex Account Manager to enable payment acceptance using Hosted Payment Page for your merchant account.
Obtain your access token API by authenticating to Airwallex using your unique Client ID and API key. You will need the access token to make API calls.
Read the
airwallex-payment-elementsJavaScript client library reference JS to familiarize yourself with the Hosted Payment Page methods, parameters, and properties.Install the
airwallex-payment-elementspackage using Yarn or NPMyarn add airwallex-payment-elementsnpm install airwallex-payment-elements
Create a PaymentConsent if you want to save shopper’s payment details for future payments.
Step 1: Set up the server to create a PaymentIntent
When the shopper begins the checkout process, you will need to create a PaymentIntent object to indicate your intent to collect payment from the shopper.
When the checkout page loads, on your server, call Create a PaymentIntent API API with an amount and currency. Always decide how much to charge on the server side, a trusted environment, as opposed to the client. This prevents malicious shoppers from being able to alter the payment amount.
Provide return_url in Create a PaymentIntent API if you want to offer alternative payment methods (Alipay, Dana, KakaoPay, etc) that redirect shoppers to a partner site. The shopper will be returned to the return_url after the payment is complete, whether successful or otherwise.
The PaymentIntent’s id and client_secret are returned in the response — these parameters let you confirm the payment and update card details on the client, without allowing manipulation of sensitive information, like payment amount.
To display order information on the Hosted Payment Page, provide the order object with the product information when you call Create a PaymentIntent API.
Step 2: Initialize Airwallex on your checkout page
First, you will need to import the airwallex-payment-elements SDK and then initialize the package. For details, see Initialize Airwallex JS.
Step 4: Retrieve the payment result
Upon completing the payment, your shopper will be redirected to one of these URLs, successUrl , failUrl, cancelUrl, provided in redirectToCheckout( ) method, and the PaymentIntent id will be appended to the URL.
For any actions subsequent to the payment such as shipping goods or sending email receipts, you can retrieve the payment result using the following options:
Set up webhooks to receive notifications on whether the payment has succeeded. Airwallex sends payment_intent.succeeded event when a payment succeeds. Listen to these events rather than waiting on a callback from the client. On the client, the shopper could close the browser window or quit the app before the callback executes. For information on how to set up webhooks and listen to events, see Getting started with webhooks
On your server, call Retrieve a PaymentIntent API to check the PaymentIntent status.
Check Payment Activity screen on your Airwallex web app.
Test your integration

FAQ
What are the common scenarios with a Hosted Payment Page integration?
Some common scenarios include :
| Error | Next steps |
|---|---|
| Airwallex is not defined | Check if you have initialized Airwallex (Step 2) before using Airwallex functions. If you are using CDN, check if you have changed the bundle version from x.x.x to the latest version in the package.json file. For example, https://checkout.airwallex.com/assets/elements.bundle.min.js is invalid |
| Access denied, authentication failed | Check if you have replaced your intent id and client_secret in createElement() and optionally confirmPaymentIntent(). |
| The PaymentIntent with ID int_xxxxxxxxx cannot be found | Check if the environment you initialized Airwallex in, for example, demo or prod, matches the environment you retrieved your intent id and client_secret from. In other words, if you ran init in the demo environment, you must also create your PaymentIntent in the demo environment. |
| InvalidAccessError: Page already has an active payment session | ApplePay doesn't allow duplicate sessions in the same page. However, you may create the apple pay element multiple times, please follow either of the options listed to address the error: 1) Call the destroy function to destroy old element before you create the new element. 2) Call the update function to update the old element with new intentId. |
