PayTabs Node.js Package makes integration with the PayTabs payment gateway very easy by providing a ready-made payment class that handles the card entry and, billing & shipping information and completes the missing details.

To refund a transaction means to return/transfer back a transaction amount from your bank account to the customer's bank account. It will be logged as a new separated transaction with this type, and it will be related to the previous "Sale" or "Capture" transaction. In this article, we walk you through how to use and manage the below function:




let transactionCreated = function ($results){
    console.log($results);
}

paytabs.queryTransaction(
    transactionDetails,
    cartDetails,
    transactionCreated
);
Refund request is available ONLY for those authenticated "Sale" transactions or authenticated "Capture" transactions
