I've got a general question about tokenaztion and storage of the credit card number. The application is a WordPress website and matching native mobile application. Can the Express API be called without storing the credit card number without our system? I'm a system integrator and trying to understand if we must store the CC number while the transaction is being authorized. I'm attempting to minimize would PCI DCC requirements by ensuring we don't store the CC number anywhere but in the application memory.
If you have any examples of this architecture, I would be happy to hear more from you.
