Real-time Events

You can connect to the web socket server and get an instant stream of data from the service once an update occurs, you can do this by using the Socket.io Framework. this is available in multiple languages like JavaScript and Python, it can also be done both on the client and server-side.

Example connection from the client-side in a React Application using the socket.io-client package:

import React from "react";
import io from "socket.io-client";

const socket = io("KRAKEN_API_INSTANCE_URL");

socket.on("feedUpdate", (data) => {
  // the data stream is passed to the `data` variable.
});
