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

  1. The shopper chooses to pay with GoPay
  2. The shopper is redirected to GoPay page where order details are displayed
  3. The shopper enters their PIN to confirm the order
  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 GoPay 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.

Request:

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 GoPay to complete payment

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

  1. Obtain URL from Airwallex and redirect shopper to GoPay

  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 GoPay.

  1. Query the PaymentIntent status

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