All attempted credit card transactions can be viewed in the I18 Credit Card Transaction Report. It can be used for reconciling all Credit card transactions done through the payment gateway set up for the practice. All successful and failed transactions are listed here along with the reason for the failure (if any). Each line in the report lists the Payment#, Amount, Payee Name, Payment Date, MR#, Transaction Status (Processed/Pending/Completed/All), Payment Partner, Gateway Transaction ID, Gateway Transaction message, and Batch number.
