PromptPay Transaction Requests {#thunes-promptpay-intro}
========================================================

PromptPay is a payment method offered by the Thunes payment service provider (PSP) that you can offer your customers through `Cybersource`. You can process a payment by sending a sale API request to `Cybersource`. `Cybersource` sends your request to Thunes. Thunes approves the transaction and sends the request to the processor for settlement. You can also send a check status API request to retrieve status updates of the processing sale. PromptPay does not support refunds. To issue a refund to the customer, you must provide an alternative method of reimbursement, such as cash or in-store credit.

Requirements
------------

You must have a merchant ID and a Thunes API key for each country in which you process transactions. Contact your `Cybersource` account manager for more information.
