my eshop is located in Greece, and i would like to use a local payment gateway, supported by the greek bank "Alpha Bank" (it's using Delta Pay).
How can i do this?
Generally speaking you cannot add a custom payment gateway to process credit cards online. This has to do with the fact that all credit card processing has to go through our ActiveMerchant protocols in order to be securely processed to protect both the customer and the shop from potential problems that can arise from a non-secured gateway.
As it stands right now, the only payment gateways that we support in Greece are found on this page here:
Talk to you soon!
Alpha Bank should have access to the First Data platform (Omaha) I believe. Here's what you need to do, get a PayPal Payflow Pro gateway (works with Shopify) and get a VAR sheet (setup forum basically) from Alpha Bank and get this over to PayPal. This should solve your problem and allow you to use Alpha Bank.
Sorry for the delay in getting back to you! Though FirstData is a gateway that we integrate with in the United States, we simply do not have the ability to integrate with FirstData (and therefore Alpha Bank's Delta Pay) in your region. For the time being, you will simply have to use one of the gateways that are on the list that I linked to previously.
