We have not figured it out yet but are still working on it.
We are also wondering the same question! I believe that WorldPay has a Shopify integration and that is how we accepted EBT payments previously. Wondering whether you figured this out? Thank you!
hi @jimelaine ,
One option is to integrate SNAP/EBT payment gateway as a private app with SNAP/EBT options .
We are a Shopify partner and happy to assist you developing and integrating such a private APP.
DM me for more details.
