FAIL

Value Range: FAIL/SUCCESS/CLOSED/NOTPAY/PAYERROR/PENDING/NOTSURE/USERPAYING/REFUND

  • FAIL: stands for the order query operation failed for some reasons, such as: the order no. could not be found in the ksher database or some parameters are not correct, etc. , it does not means the order failed, merchant should decide the next step according to the error code.

  • SUCCESS: Payment successful, customer already paid.

  • CLOSED: the order is closed, so customer will be not able to pay it any more.

  • NOTPAY: customer quit the payment window, so payment not finished.

  • PAYERROR: the order failed for some reasons, like: wrong password, errors occurred between wechat and bank.

  • PENDING: order pendding on enter PIN

  • NOTSURE: unknown status. on between waiting customer paid..

  • USERPAYING: Wait customer enter PIN. waiting and then call the Query Order API again to check current transaction status.

  • REFUND: the order has refunded partially or completely.

  • Note: after order apply, merchant should regard SUCCESS as final result, the rest result :"NOTPAY/PAYERROR/PENDING/NOTSURE/USERPAYING" means real time status , not the final result, user still can pay again. "FAIL" Only happened when payment channel bank system error, which happens very few. "REFUND" means this amount already turn back to consumer’s.

  • Query Suggestion: Merchant should continue Polling query order result Until you got SUCCESS or over polling time limit. The time limit of polling query should be one day time (45mins once a second and then half an hour , one hour once) just in case. The Actually the "expire_time" is only limit the gateway page valid time. As long as your user redirect to KTB Payment page within gateway expire time, he still can pay with this order after time expired because he is already left gateway page and stepped into KTB Payment page, in which Ksher can not control. so please polling query payment result very often within your expire_time+15mins ,for example every second. If after 45mins it still not SUCCESS, continue polling query for one day but not that often , maybe half an hour , two hour a time.
