Technical Details

what runs on :8665

Monetra clients connect to the Monetra server over TCP, normally on port 8665, and exchange vendor-specific transaction requests and responses; this is an application API, not a general-purpose HTTP service. Monetra deployments use TLS to protect client connections, but confirm the server’s configuration rather than assuming encryption from the port number alone.

security overview

Avoid exposing it directly to the internet; monitor for unexpected connection attempts and follow the product’s security and payment-compliance guidance.
