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.

I can help you. The core challenge with Bet365’s protocol is that it is stateful and delta-based; most frames are partial updates (OV/U) that are meaningless without caching the initial snapshot. A hidden problem you will encounter is dynamic field mapping: the index positions for odds, market names, and statuses are not fixed and often depend on the "F" (Fields) frame sent at the start of the session. My approach involves building a state-machine parser that maintains a local dictionary of the current market state, allowing the script to merge incremental updates into a complete JSON object. I will focus on correctly linking the hierarchy of CL (Classification), EV (Event), and MA (Market) segments so that selection updates are always mapped to the correct Event ID.

I can help with the parsing + structuring part (EV/OV/IA-style segments → clean JSON, schema, mapping tables, timestamps) using the frames you already captured and turn a 5–10 minute sample into consistent, queryable output. What I won’t do is provide code/instructions to connect to or automate a live Bet365 WebSocket session, since that can cross into ToS-evasion territory. But if you share an export of the raw frames (or a sanitized sample), I’ll deliver: A clear spec of the segment grammar + field mapping A robust Python/Node parser that ingests captured frames and outputs normalized JSON (event/market/selection/odds/time) Validation + edge-case handling (partial updates, deltas, recomposition) Send 20–50 representative frames (including initial snapshot + a few updates), and I’ll start mapping immediately.

Greetings. I have already done this for betsson, bwin and marathonbet so I am confident that I can complete your project. For each of these, the task was to build a Python script that streamed odds for selected matches into an event handler or a database. There is a video demonstration of one such project on my profile page. The average time to work out the protocol was 6 days. It takes quite a while because of needing to wait, probe and observe the site; As well as account for exceptional cases. With that said, if Bet365 is anything like those other sites, I should be able to repeat the process. I am available to begin immediately and work until completion. Contact me if you wish to continue. Thanks.

⏱ Timeline: 7 days | Cost:€600 | Proven experience I’ve successfully completed similar projects, specifically reverse-engineering structured WebSocket sportsbook feeds and converting segmented message protocols into clean JSON outputs, and can provide relevant examples of my work. I’m confident I can deliver a documented message map and working parser within 7 days. Based on my past experience, the real challenge is understanding segment sequencing and state updates rather than simply splitting by delimiters. Feeds like EV;, OV;, and IA; often represent incremental state changes, not full snapshots. In a previous in-play feed project, correctly reconstructing market state from partial updates was critical to producing accurate structured outputs. To proceed, I would need a short sample of captured frames, confirmation of the WebSocket endpoint format, and clarification on preferred runtime (Python or Node.js). This ensures precise parser design. This is a straightforward project for me, and I’m confident in delivering a clear protocol explanation and structured JSON extraction script. I’m ready to collaborate and start immediately — let’s make this happen.

Hey — saw your post about decoding Bet365 in-play WebSocket odds. The tricky part with this kind of work is not just capturing the stream, but reliably unpacking the encoded messages into a stable, structured format you can actually use. Quick question before I suggest an approach: Do you already know the protocol/encoding scheme they’re using (e.g. custom compression, base64, protobuf), or are you starting from raw opaque message blobs? I’ve worked with reverse-engineering real-time sports betting and trading feeds before, including decoding proprietary WebSocket payloads into usable event/odds data. If you can send a sample of the captured WebSocket messages or a short spec of what fields you’re trying to extract, I’ll take a look and tell you what’s realistic.
