# Websocket API

> Real-time data via the SX Bet WebSocket API

<Warning>
  This WebSocket API will be deprecated on July 1, 2026. See the [Migration Guide](/api-reference/centrifugo-migration) to move to the Centrifuge-based API.
</Warning>

You must have a valid API key to subscribe to realtime channels via the API. See [API Key](/api-reference/api-key) for more info.

You can connect to the websocket API and listen for realtime changes on several resources such as the order book, markets, scores, and line updates.
