Need a Magento Plugin

You'll develop the plugin in magento(1.x and 2.x). We need both. It will be a simple plugin. The php, woocommerce, and prestashop plugins are already developed. Here is what we need- In the shopping cart, after submitting the checkout page for order processing, the order detail will be sent to the plugin (which you’ll build) in the background (meaning the checkout page shouldn’t be refreshed). The plugin will send this info to a bank api (this api is already built and we’ll supply to you). The bank api will process the card and return success or failure message (so, you need to do anything here). You will then display that message to the checkout page. That’s it. - Magento developers are invited only. - Please mention your previous work experience on magento. - Please consider that we're looking for a long term relationship. - Please mention why you're capable of doing this project clearly, else we'll not response to your bid. - You must have professionalism to provide future support if it is required.
