Mobile Website Browser - Kakao Pay

Create a Payment Intent with the Create a Payment Intent API API.

POST /api/v1/pa/payment_intents/create

When a shopper selects to pay with Kakao Pay on their mobile browser, call the Confirm a Payment Intent API API to get a redirect URL.

POST /api/v1/pa/payment_intents/{id}/confirm

You will get a response similar to the following.

You should redirect the shopper to the Kakao Pay page with the next_action.url returned in the confirm Payment Intent response.

Note, if you use the mobile browser flow in your app’s Webview and pull up the Kakao Pay app, please add the HTTP header Referer when you request next_action.url. Otherwise, you may be unable to pull up the Kakao Pay app on the shopper’s mobile phone if the shopper chooses to pay in the Kakao Pay app. For example:

Andriod

iOS

Multiple redirections may happen after visiting next_action.url. When handling redirection to a non-HTTP URL, please add special handlers when you want to start the provider app on the shopper’s mobile phone. For example:

Andriod

iOS

To get the payment result, we suggest you poll the status of the Payment Intent via the Retrieve a Payment Intent API API. You may start polling the Payment Intent status after the shopper is redirected back to your website or mobile app, i.e., the return_url passed when creating the Payment Intent.

GET /api/v1/pa/payment_intents/{id}

In addition, Airwallex will notify you of the payment result asynchronously via the webhooks. Please refer to the webhook documentation to set up your webhook accordingly. Although subscribing to webhook events is optional, it is recommended to subscribe to the payment_intent.succeeded webhook which indicates that the shopper has paid the order.
