Support for NMI Gateway Ending in 2025 Published May 24, 2024 The original NMI gateway, integrated into Rock since version 5.0, is now in "maintenance" mode and will be phased out by June 2025. If you are still using the "Network Merchants (NMI)" gateway in Rock v15 (and earlier) or the "Celero/TransNational NMI Gateway" in v16, thereʼs no need for concern. My Well Ministry offers excellent support for a seamless conversion to their next generation gateway. In fact, Spark completed this same conversion last October without any issues. If you registered for RX this year, you even used the My Well gateway! Connect with My Well today and start your migration. My Well is ready to assist all organizations with the transition.
