Line Changes

Subscribe to all line changes. Messages are sent for particular combinations of event IDs and market types. Note that only market types with lines will have updates sent. See the active markets section for details on which types have lines. CHANNEL NAME main_line:global MESSAGE PAYLOAD FORMAT

Name	Type	Description
marketHash	string	The market which is now the main line for this event ID
marketType	number	The type of market this update refers to
sportXEventId	string	The event ID for this update

To get the actual line, fetch the market using the marketHash.

// To subscribe
const sub = client.newSubscription("main_line:global", { positioned: true, recoverable: true });

sub.on("publication", (ctx) => {
  const data = ctx.data;
  // message handler logic
});

sub.subscribe();

import asyncio
from centrifuge import Client, PublicationContext, SubscriptionEventHandler

async def on_publication(ctx: PublicationContext) -> None:
    print(ctx.data)

async def main():
    client = Client(
        "wss://realtime.sx.bet/connection/websocket",
        token="YOUR_TOKEN",  # from /user/realtime-token/api-key
    )
    await client.connect()
    handler = SubscriptionEventHandler(on_publication=on_publication)
    sub = client.new_subscription("main_line:global", handler)
    await sub.subscribe()
    await asyncio.Future()  # keep running

asyncio.run(main())

The above returns JSON structured like this:

{
  "marketHash": "0x38cceead7bda65c18574a34994ebd8af154725d08aa735dcbf26247a7dcc67bd",
  "marketType": 3,
  "sportXEventId": "L7178624"
}
