đī¸ Transaction Enquiry
If the mchid is provided, it is mandatory to submit the mchid when calling the API (unless otherwise specified). On the contrary, if mchid is not provided, merchants shall not pass the mchid field in the API request.
đī¸ Reversal/ Cancel
Reversals should be used as a last resort when the transaction status cannot be determined, e.g. no payment notification is received, the response timed-out, there are network issues, etc. The query API endpoint should be used first to check the transaction status. Hong Kong PayTypes do not support transaction cancel.
đī¸ Refunds
Only transactions with the return code 0000 (transaction successful) can be refunded.
đī¸ Asynchronous Notifications
To configure your notification URL of choice, please send the address as well as merchant and store information via email to technical.support@qfpay.com
đī¸ Transaction Notes
This Endpoint is only available to merchants who do not pass in the mchid
