Reference Pages

Reference	Covers
TCP Command API	Persistent-connection command & control — dotted/comma syntax, Global/Composition/Timeline/CueList commands, example sessions, connecting from Medialon/Crestron/QSC/CueLab
UDP Command API	Connectionless command & control — the same command set as TCP, and when to use UDP instead
HTTP REST API	Stateless HTTP endpoints for transport, cues, CueLists, and media seeking
Effects Reference	The in-engine visual effects — every effect id, its parameters, and the effect-name / effect.* values that set them from any protocol

If you only need a browser page that fires cues and shows status, you do not have to work at this level: Custom Web Interfaces wraps the REST API in HTML attributes.

These are detailed specifications, not tutorials — most feature and workflow pages link back here for the full command/parameter list rather than repeating it.
