I've affiliated with EaseBuzz, an Indian Payment Gateway provider...
They have provided me with an API Integration Kit.
However, I'm not able to figure out which file in AbanteCart to EDIT to allow integration of the same. Pls direct if there is already a Topic in the Forum. Thanks
Admin : I've also referred them to AbanteCart ... I can give you the Contact emails of the Dev head if someone can PM me for it...
