To add a new payment press the + icon and enter new payment names and details. Navigate Credit Card or Bank Account using the tabs. The account name is pre-filled from the customer name.
Click save and then add 'Rewrite PDF' in the event. Data in the PDF agreement will rewrite with the updated data.
For Credit Card transactions, don't forget to tell your payment gateway if amounts or frequencies change. Floodgate only communicates with the credit card payment gateway at the initial point of acquisition.
