QST WebSocket API - JSON Protocol Documentation

The underpinning of the QST WebSocket API is a JSON-based data exchange implemented on top of the WebSocket Secure (wss) communication protocol.

This JSON protocol is used in the communication between a QST WebSocket API client application and the QST Professional desktop trading platform.

A complete specification of the WebSocket and WebSocket Secure protocols can be found in IETF RFC 6455.

A complete specification of the JSON data interchange format can be found in IETF RFC 8259.
