Supported by major banks such as Bangkok Bank, Kasikornbank, Siam Commercial Bank, and Krungthai Bank, transfers can be made through branch services, ATMs, internet banking, and mobile apps. Domestically, the PromptPay system enables near-instant transfers using just a phone number or national ID. The system is regulated by the Bank of Thailand, ensuring security, efficiency, and nationwide accessibility. Learn more about Thailand Banks.

Pick the desired authentication method

REDIRECT

Redirect your consumer to the returned $.authenticationMethods[?(@.type == "REDIRECT")].details.requestUrl.
For example, with the value of https://redirection-target.ppro.com/ using the returned $.authenticationMethods[?(@.type == "REDIRECT")].details.requestMethod HTTP method.
The consumer will be presented with the reference number and instructions to complete the payment.

Handling the payment result

REDIRECT

After the consumer completes the payment, they are redirected to the returnUrl specified in the payment charge creation request.
Upon redirect back to your site, retrieve the latest payment status by performing a GET /v1/payment-charges/{paymentChargeId}. Use the returned status field to determine and display the final payment outcome to the consumer.
Additionally, webhooks are triggered to notify you of the payment result. This ensures you receive the outcome even if the consumer closes their browser or fails to return to your website.

Payment instrument

An instrument of type BANK_ACCOUNT will be created for Thailand Banks payments where the consumers bank account details can be returned.
