When "Check Cashback Details" is executed right after "Give Cashback to User", the TRANSACTION_NOT_FOUND error may occur. We therefore ask you to wait for approximately 1 second after "Give Cashback to User" to execute "Check Cashback Details."
For the TRANSACTION_NOT_FOUND error in Check Cashback Details even after waiting for about 1 second, check the following:
- If merchantCashbackId is correct, please set the same merchantCashbackId and then execute "Give Cashback to User" again.
※If you execute a request with a different merchantCashbackId, there is a risk of duplicated granting. - If merchantCashbackId is wrong, please set a correct merchantCashbackId and then execute "Check Cashback Details" again.
