PromptPay

Testing

Currently PromptPay testing capabilities are limited, and the most reliable way to conduct comprehensive end-to-end testing is within the pre-production environment.

When using the pre-production environment for testing your integration with PromptPay, please be aware that there are significant deviations from the real-time experience that consumers will encounter in the production environment.

In the pre-production environment, testing responses are simulated through a stub, which automatically provides feedback after a delay of approximately 3 seconds. However, keep in mind that these responses are based solely on the selected amounts and do not reflect a complete user experience. Responses are predetermined and may not accurately mimic live interactions. Additionally, the Refunds via Bank Transfer (PPID 1041) cannot fully be simulated on pre-production.

In the pre-production environment, once a payment is created and the QR code is displayed on the merchant's website, the consumer does not need to scan the QR code. Instead, after a delay of 3 seconds, the payment status is automatically updated on the merchant's platform based on the predetermined amount selected for the test. However, this does not reflect the actual process used in a live setting where the consumer must manually scan the QR code to complete the transaction.
