Integration with WP Give

I have tried to integrate this plugin with WP Give with no success. I have even engaged an IT expert and no solution was forthcoming.

I like WP Give because it enables me to track donations easily within WP and without having to use another 3rd Party app. It currently integrates with PayPal but I need a solution for Airtel Money & Safaricom MPesa.

Have you done any work on integrating with WP Give?
