Processor IDs for Multi-MID Routing

If your NMI account has multiple MIDs:
  • Each MID will have a unique Processor ID.
  • Record the Processor IDs, we will need them to route specific transactions from Paysight to the correct MID.
  • If you don’t set a Processor ID, transactions will go to the default MID.
You can check the Processor IDs navigating to:
  1. Options > Settings > Transaction Routing
