airwallex-payment-elements

This airwallex-payment-elements library is a lightweight javascript SDK that allows merchants to conveniently integrate the Airwallex checkout flow on their website.

Check out our demo here.

How it works

Merchants can integrate airwallex-payment-elements in the checkout page on their site. For every checkout, merchants should create a PaymentIntent entity through the Airwallex API to process payments with Airwallex.

Once the PaymentIntent is successfully created via API integration, the API will return a response with a unique ID and client secret for the intent. Merchants can then use these two keys to enable the payment elements to collect payment attempt details.

Payment Methods

The package includes different payment processing elements that will allow merchants ot accept payments on their site. We have 6 different checkout elements:

• Hosted Payment Page (HPP): Merchants can accept payments without the full handling of the payment processing and display of the payment options.
• Drop in: Merchants can accept payments without full responsibility of handling their payments but can still control the overall look and feel of their payment page.
• Embedded Fields (Elements): A set of prebuilt UI components, like inputs and buttons that Merchants can directly place in their checkout flow (more below)
  • Full Featured Card
  • Split Card
  • Wechat Element

The primary focus of this library is Elements, which enables Merchants to collect sensitive information (PCI) using customizable UI elements. This library also provides a single interface for interacting with the Payment Request API, allowing for the tokenization of sensitive information and handling of 3D secure authentication flows.

Elements includes the following features:

1. Automatic formatting of card information in the input field
2. Customize placeholders to fit Merchant UX/UI designs
3. Responsive design
4. Flexible/Customizable styling to match the look and feel of the Merchant's checkout flow

Installation

Install with Yarn

yarn add airwallex-payment-elements

Or, with NPM

npm install airwallex-payment-elements

Getting Started with the Airwallex Card Element

The Card element is one of Airwallex's most popular payment integration. It is a single line multi-input field containing card number, card expiry, and card cvc.

Detailed Card integration guide here. More extensive documentation details below

Initialize Airwallex:

import Airwallex from 'airwallex-payment-elements';

Airwallex.loadAirwallex({
  env: 'demo', // 'staging' | 'demo' | 'prod'
});

Create a container for your payment element in HTML:

<div id="card"></div>
<div id="submit">Submit</div>

Then create and mount your payment element in Javascript:

const cardElement = Airwallex.createElement('card', {
  intent: {
    // Required, Card uses intent Id and client_secret to prepare checkout
    id: 'replace-with-your-intent-id',
    client_secret: 'replace-with-your-client-secret',
  },
});
cardElement.mount('card'); // Injects iFrame into element container

Add an event handler to the button to trigger payment confirmation

document.getElementById('submit').addEventListener('click', () => {
  Airwallex.confirmPaymentIntent({
    element: card, // Must link element
    id: 'replace-with-your-intent-id', // Same as intent details from above
    client_secret: 'replace-with-your-client-secret',
  }).then((response) => {
    // Listen to the payment confirmation response
    window.alert(JSON.stringify(response));
  });
});
}

Add onReady, onChange, onSuccess, and onError event listeners to handle various events received from the Airwallex Payment server.

// Replace EVENT_TYPE with 'onReady', 'onChange', 'onSuccess', or 'onError'
window.addEventListener(EVENT_TYPE, (event) => {
  /*
  ... Handle event
    */
  window.alert(event.detail);
});
