When we are doing the sale transaction by selecting debit option after card swipe, the transaction getting declined every time, we have tried multiple cards for the same but no luck, so can you please let us know if we missing something in it or do we need to configure missing cards under merchant setting on clover portal? If yes Can you please let us know where and how to configure the cards?
(we are using Payment Connector integration for the same).
