I am working on analysing the in-play WebSocket traffic of Bet365 (already captured via browser DevTools). I have already: Captured raw WebSocket frames Identified that messages are plain-text structured segments (e.g. EV;, OV;, IA;) Observed updates related to in-play football markets The task is NOT to bypass authentication, but to: Decode the message structure. Map message segments into structured JSON. Extract: Event ID Sport Market name Selection name Odds Timestamp Deliverables: Technical explanation of message format. A small Python or Node.js script that: Connects to an already authenticated WebSocket session Parses frames Outputs structured JSON 5–10 minute sample capture (football in-play) The WebSocket frames are already accessible; focus is parsing and structuring. Experience with sportsbook feeds or protocol parsing is preferred.
