The CAM (Customer Account Manager) is your customer's access to their account information including their billing and contact information, any rebill agreement information (including the ability to change credit card authorization), as well as payment/purchase history.
These management screens are provided for you to be able to view this information, as well as to cancel a rebill agreement, if necessary. Unlike your customer's CAM, these screens do not give you the ability to change the authorizing credit card or customer contact information.
