[Membership 2 Pro] Bluefin PayConnex Gateway Integration

Hello! I need some guidance on how to begin the process of integrating Bluefin's PayConnex gateway into Membership2. PayConnex is a growing gateway in the non-profit world and I'm bumping into it more and more. They can provide full docs on their SDK and API Integrations. Can you help?
