Accept LinkAja payments on your website by redirecting shopper to LinkAja webpage. See checkout process below:

  1. The shopper chooses to pay with LinkAja
  2. The shopper is redirected to LinkAja login page and enters LinkAja ID, PIN, and SMS
  3. The shopper confirms the order and completes the payment
  4. Payment succeeds and the shopper is redirected back to the merchant’s page which displays the payment result

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 LinkAja 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.


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 LinkAja to complete payment

When a shopper selects to pay with LinkAja on their desktop/mobile browser, call the following API endpoints to get a URL, which you can use to redirect the shopper to LinkAja to complete payment.

  1. Obtain URL from Airwallex and redirect shopper to LinkAja




  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 LinkAja.

  1. Query the PaymentIntent status

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