2. 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 Singapore Kiosk Payments.

3. Query the PaymentIntent status

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

Shell
1    GET /payment_intents/{id}
