Yet another extension development for Magento core 1.9.x. Our developers are busy developing a Magento extension for Green money. We are using their API to build this with our own PHP library for Magento. Contact us if you want us to develop a custom payment gateway extension for Magento.
We have worked with Amember and Noire earlier in integrating both. Now we have started developing BlueSnap payment gateway plugin for Amember. It is little different when compared to other payment gateways. For now, we are working for subscription products only. Do contact us if you want to know more.
