Hello! I am trying to integrate payment API from Bank of Georgia to shopify. I have successfully created app, but when adding extension as for payment gateway app there are nothing to add. Can you help with this? I have already contacted Bank of Georgia technical support and they have no clue and suggested to contact shopify support. My shopify partner test store is https://fshtestshop.myshopify.com/. I have requested mandate API, not sure if I need it. As suggested in payment app development guides I have tried to create an extension On payments section of extensions but there are No extensions available. I have all the API code necessary provided from Bank of Georgia. I have used node template for this app. I have been approved as shopify partner.
