# TNS

LUSID’s Transaction Network Services (TNS) integration allows LUSID to receive FIX order and execution messages routed through TNS's financial extranet and managed connectivity service. If you use TNS as your network provider to reach brokers and venues, this integration makes LUSID a natural endpoint in that flow, capturing trade data without requiring a separate connectivity layer.

> For this integration, LUSID uses FIX trading messages to communicate with the external system. To set up and use this integration, [follow this FIX trading integrations article](/v1/docs/fix-trading-integrations).
