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 banks
Thailand Online Banking requires bank_name when confirming the Payment Intent, you can call this API endpoint /api/v1/pa/config/banks with payment_method_type, country_code and lang to get available bank names based on the payment method selected.

Alternatively, you can maintain a list of available banks locally on your server for payment methods that require bank_name if you do not want to use this API endpoint. However, we highly recommend you get the banks dynamically from this API to avoid any trouble when bank information or availability gets updated.
Supported banks:
| bank_name | Display Name |
|---|---|
bangkok | Bangkok Bank |
krungsri | Krungsri Bank |
krungthai | Krungthai Bank |
kasikorn | Kasikorn Bank |

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 Thailand Online Banking.
