WebSocket subscribe filters

Answer: send one JSON subscribe frame after connect. Filter with sports, markets, live, main, and specials so the server drops unwanted markets before your client sees them. Builder required (€99/mo).

Example#

{
  "type": "subscribe",
  "sports": ["soccer", "tennis"],
  "markets": ["moneyline", "spread", "total"],
  "live": true,
  "main": true,
  "specials": false
}

Change filters anytime by sending another subscribe (no reconnect). Full list: WebSocket docs.
