# WebSocket API

The lifecycle of a Websocket connection is as below:

1. Open a Websocket connection to `ws.aevo.xyz` (or `ws-testnet.aevo.xyz` for Testnet).
2. Authenticate for private operations.
3. Subscribe to a channel.
4. The connection will start streaming data from the subscription.
5. Connection will time out after 15 minutes of inactivity. To keep the connection alive, perform a `ping` operation. Sending any other operation will also refresh the connection.
