It's really simple to view and download transaction records in your Control Center.
View All Transactions
By clicking on the Giving tab, you can see a list of all your recurring gifts and transactions.
By default, you'll see all records, but you can drill down on specific information by clicking on the Filtering Options, Choose Date Range button, choosing what information you see listed via the Columns button or by searching for something specific. From here you can either view additional details about a specific gift or download the transaction record.
You can click the Download Report button for your current transaction list in CSV format.
You can find additional details about a specific transaction by clicking View on that specific gift row.
