Enable Payment Gateway

Hello - I am a payment gateway trying to find anyone that can talk to me about enabling my merchants to accept apple pay ecomm. Thank you for any direction or URL for more info, cwl

To be clear - I have about 1500 Merchants actually interested in adding apple pay to their payment acceptance types. They are already enabled via hardware. They now want to know how to connect my gateway to enable apply pay ecomm transaction. Please let me know if this is similar to Verified by Visa and Mastercard SecureCode in that there is an Authentication and simply a PAN exchange or if this is going to require my gateway do a full certification to another platform.
