    -d '{

      "amount": 50,
      "currency": "KRW",
      "merchant_order_id": "85d7b0e0-7235-11ea-862e-9f6aa1adfca6"
      "return_url": ""

Step 2. Redirect to Kakao Pay Cashier to complete payment

When a shopper selects to pay with Kakao Pay on their desktop browser, call the following API endpoints to get a e-wallet cashier URL, which you can redirect the shopper to Kakao Pay cashier to complete payment.

  1. Obtain URL from Airwallex and redirect shopper to Kakao Pay cashier

Request:{id}/confirm \
      -H 'Content-Type: application/json' \
      -H 'client-secret: Ss3thJHPE6TyI4r-8BJFlqNz1mA7DblVuN0c8GOthnchp7Sf-_JuQnuX3sqzv7_0EiTMOs2kcGopFrMoFC0w7IzPCErJ1a0P7sFnpwB6uz-H2h_6rDhhSd2tKJF-l2myVOXQV4Zou3s_OsX6thLiUKI=" \
      -d '{"request_id": "ed11e38a-7234-11ea-aa94-7fd44ffd1b89",
"type": "kakaopay",
  "kakaopay": {
     "flow": "webqr"

      "next_action": {
      "type": "redirect",
      "method": "GET",
      "url": ""
  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 Kakao Pay.

  1. Query the PaymentIntent status

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

    GET /payment_intents/{id}
