RadicalMart Payment: Payselection

RadicalMart Payment: Payselection is a payment gateway plugin that integrates the Payselection payment platform with RadicalMart.

The plugin acts as an adapter between RadicalMart's payment system and the Payselection API. It allows store orders to be processed through the external payment service while keeping order logic within RadicalMart.
