I would be really helpful if anyone provides a solution to know, how do we add the credit/debit card details to Wallet from our App. I have the credit/debit card details for the user and when user tap on Apple Pay option in my App, the Add Card screen in Apple Wallet need to be opened with card data pre-populated. How do we achieve the same.
Thanks in advance
The good news is that this can be done. What you are looking for is In-App Provisioning of Payment Cards. This is done using the PKAddPaymentPassViewController, which requires the com.apple.developer.payment-pass-provisioning entitlement key for your app. The bad news is that not anyone can submit apps with this entitlement as it requires special permission from Apple, which I believe is reserved for card issuers like banks and similar. If you believe that you qualify you need to contact Apple directly at apple-pay-inquiries@apple.com.
Apple only want to communicate with bank.@pajevic
Abreast of the times email address is: apple-pay-provisioning@apple.com
on the https://developer.apple.com/apple-pay/ we can find in Lower right corner
