Hi. I have a few questions about using Apple's MPAN tokens. Since Apple doesn't provide MPAN tokens in the sandbox environment, I'm having trouble understanding the differences between the MPAN and DPAN flows. I'm guessing they're the exact same, except when we detect the MPAN we save some information so we can use it in future transactions. If that's correct, my questions are:
- What information in the Apple Pay payment data indicates that it's an MPAN vs when it falls back to DPAN
- Like DPAN, the MPAN can be found in applicationPrimaryAccountNumber? Or is it found in the merchantTokenIdentifier?
- What is the bare minimum data needs to be stored in order for these merchant tokens be reused for future transactions?
