This payment extension for Magento 2.3 is designed for making credit card payments through Alpha banks e-Commerce system (Greece).
This payment gateway uses the redirect method where the user is redirected to the processing site (Alpha bank) to make the actual payment.
After payment verification, Alpha banks e-Commerce system notifies the merchant's e-commerce site and returns the customer back to it. This process is transparent for the customer. The merchant can then connect to his Alpha bank backoffice to administer his payments.
This module supports free and charged instalments and has a separate payment option for Masterpass.
