====== Legacy T4 API's ======

We remain committed to supporting our legacy .NET and FIX APIs for existing integrations. However, for all new integration projects, we strongly encourage looking at our [[api:websocket|WebSocket API]], which is a modern real-time high performance API which works on any platform.
