Question
How can a credit card be removed from PBA?
Answer
Expired credit cards can be removed from the provider's control panel (PCP) - Home > Operations > Expired Credit Cards
It is possible to wipe out the credit cards (including active ones) from PCP - Home > Operations > Payment Methods
A single active credit card can be removed only from the customer's control panel: Parallels Panel > Account > Payment Methods > Payment Method #ID "Delete" button. There is a feature request with id #PBA-48287 to implement ability to delete the credit card from the PCP.
There is also a feature request with id #PBA-48286 to implement API method for a credit card deleting.
Please note that credit card removal means the card is not visible in the control panel, but the records about it (non-sensitive information) are kept in the database.
