With card present environments, what's happening there is Apple Pay is sending the DPAN and cryptogram to the terminal, and terminal completes the charge. However, in card not present environments, from a payment processing UX perspective, the user has to see the amount they are confirming for pre-authorization. Otherwise it could lead to fraud cases. You could consider talking to your gateway or bank for Credential On File (COF) if you want to implement something similar to card present environments: You can save the card with a symbolic amount (or zero if the banks allow it) and then use the card you saved for the actual charge. But please beware that Credential On File brings its own set of rules and implementation requirements.
