Michael Normally you can use the listing method from the NoteAttachmentMasterCardAction class to get the card payment attachments. But it looks like there is a bug in this method, because it returns an error.
I've created a workaround for this issue:

Btw, If you want to create a statement (with all transactions for a card) you can use the create and get methods from the ExportStatementCardCsv class.
