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?

I'm trying to enable merchant tokens in my test environment. I'm using the demo code below: { ... "recurringPaymentRequest": { "paymentDescription": "A description of the recurring payment to display to the user in the payment sheet.", "regularBilling": { "label": "Recurring", "amount": "4.99", "paymentTiming": "recurring", "recurringPaymentStartDate": "2023-08-11T11:20:32.369Z" }, "trialBilling": { "label": "7 Day Trial", "amount": "0.00", "paymentTiming": "recurring", "recurringPaymentEndDate": "2023-08-11T11:20:32.369Z" }, "billingAgreement": "A localized billing agreement displayed to the user in the payment sheet prior to the payment authorization.", "managementURL": "https://applepaydemo.apple.com", "tokenNotificationURL": "https://applepaydemo.apple.com" }, ... } I'm able to see the recurring prompts in the payment sheet, but after processing I do not see the merchant token anywhere. I'm looking in the paymentData object and I do not see the merchantTokenIdentifier. I've tried using the Visa, Mastercard, Amex, and Discover test cards, but still no luck. I seen similar threads on these forums, but never with an answer. Has anybody been able to test merchant tokens in sandbox?
