True for all Visa cards? Can you share the last 4 digits of the card you're using from the sandbox test cards list?

Hey, is this to add a sandbox test card to Apple Wallet? If so, the Apple ID you created as a developer and added to sandbox in developer portal, needs to be logged into the iPhone. Settings >> name at the top | if that is your AppleId, you'll need to sign out then sign in using the sandbox. Since it's the main AppleID on the device, we recommend using a test device, not your everyday device as it will wipe the cards when you sign out. hope this helps

Howdy, Great job knowing we use ISO 4217, and I agree with your findings. Payment sheet fails to open if a decimal is used in amount when type is total. We're on it,

Howdy, The payment processing certificate is needed, can you confirm you have a payment processing certificate? If Stripe is decrypting the paymentData for you, they will provide a CSR file to generate the certificate. Do you have web integration as well, I see the domains checked off - is this app and web? If web, what happens if from the top level domain you use the java console and window.applepaysession.canMakePaymentsWithActiveCard('yourMerchantIdHere')

Can you clarify your problem statement? What is not working? If you're not a PSP, you're still able to decrypt the paymentData{} yourself which allows you to route the transaction to any PSP you choose. Merchants can enable Apple Pay a couple of ways, either directly between merchant server and Apple, or through a PSP who can either host the entire payment flow or give you integration instructions and SDK. If you can clarify we can get you on the right track, Cheers.
