4 Steps to Build a Live Streaming App

This tutorial explains the steps to integrate live video streaming into your app.

1. Sign up for a free Video SDK and Generate API Key

Go to Dashboard, navigate to Settings > API Keys and click on ADD NEW button.

2. Generate access token

For security, every user that connects to live streaming needs an access token. By substituting API_KEY and SECRET_KEY  in it.

Note: Please note that this code is meant to be written on your backend server. Do not reveal your secret key to anyone. This sample is in Node.js but you can write the same in any other programming language with the help of a JWT library. Please check the JWT.io website for more details.

const express = require("express");
const jwt = require("jsonwebtoken");
const cors = require("cors");
const request = require("request");

const app = express();
const port = 9000;
app.use(express.urlencoded({ extended: true }));

app.get("/get-token", (req, res) => {
  const API_KEY = process.env.VIDEOSDK_API_KEY;
  const SECRET_KEY = process.env.VIDEOSDK_SECRET_KEY;
  const options = { expiresIn: "10m", algorithm: "HS256" };
  const payload = {
    apikey: API_KEY,
  const token = jwt.sign(payload, SECRET_KEY, options);
  res.json({ token });

app.listen(port, () => {
  console.log(`Example app listening at http://localhost:${port}`);
This guide will provide an overview of how to create live stream using generated token in previous step Authentication.

Step 3: Create a Live Stream

Use the "Create live stream" Rest API to create a new live stream. It will return the upstream and downstream URLs in response.

app.get("/live", async (req, res) => {
  const token = req.headers.authorization;
  const options = {
    method: "POST",
    headers: {
      Authorization: token,
      "Content-Type": "application/json",
    body: JSON.stringify({
      name: "Nickname for livestream", // nickname for livestream
      record: true, // use false to disable recording
  const response = await request(
  const json = await response.json();
  return res.json(json);

  1. Add media source: In the sources section, choose a video feed to share.
  2. Set streaming URL and key.
Set streaming URL and key.
