Puppeteer is a Node.js library developed by Google that offers a high-level API to control Chromium through the DevTools Protocol. You can use Puppeteer to automate tasks in Mimic browser profiles within Multilogin. In this article, we'll show you how to get started with an example.

You can only automate Mimic browser profiles using Puppeteer. Stealthfox, which is based on Mozilla Firefox, is not supported by it.

Before you start

Download Node.js from the official website and install it
Ensure Node.js and npm (Node Package Manager) are installed correctly:

node -v 
npm -v

Create a project directory, then run this command to initialize a new Node.js project and create a package.json file:

npm init -y

Install Puppeteer as a dependency for your project:

npm install puppeteer

Install Axios and MD5 library:

npm install axios 
npm install md5

Insert your values into the below variables in the script:
1. email: your Multilogin account email
2. password: your Multilogin account password (MD5 encryption is not required)
3. folder_id, profile_id: find these values using our guides on DevTools or Postman
Replace https://multilogin.com/ with the website you need in the following line:

await page.goto("https://multilogin.com/");

Running the script

Launch the app, as it makes profile launching possible
Make sure Puppeteer is compatible with the current Mimic core version – check the release notes for Puppeteer and Mimic
Run the .js file with your automation code

Make sure to run the automation code in the same folder/project as package.json file.

Script example

const puppeteer = require('puppeteer');
const md5 = require('md5');
const axios = require('axios');

const HEADERS = {
    "Content-Type": "application/json",
    "Accept": "application/json",
};
const acc_info = {
    // Insert your account information in both variables below
    "email": "",
    "password": md5("")
};

async function get_token() {
    const signIn_URL = "https://api.multilogin.com/user/signin";
    try {
        const response = await axios.post(signIn_URL, acc_info, {
            headers: HEADERS
        });
        return response.data.data.token;
    } catch (error) {
        console.log(error.message);
        console.log("Response data:", error.response.data);
        return false;
    }
};
// Insert the Folder ID and the Profile ID below
const folder_id = "";
const profile_id = "";

async function start_browserProfile() {
    const token = await get_token();
    if (!token) return;
    // Update HEADERS with bearer token retrived from the get_token function
    HEADERS.Authorization = 'Bearer ' + token;
    // Launch a profile defining "Puppeteer" as automation type
    const profileLaunch_URL = `https://launcher.mlx.yt:45001/api/v2/profile/f/${folder_id}/p/${profile_id}/start?automation_type=puppeteer&headless_mode=false`;
    try {
        const response = await axios.get(profileLaunch_URL, {
            headers: HEADERS
        });
        const browserURL = `http://127.0.0.1:${response.data.data.port}`;
        // if you prefer to connect with browserWSEndpoint, try to get the webSocketDebuggerUrl by following request
        // const {data : {webSocketDebuggerUrl}} = await axios.get(`${browserURL}/json/version`)
        const browser = await puppeteer.connect({
            browserURL: browserURL,
            timeout: 10000
        });
        const page = await browser.newPage();
        await page.goto("https://multilogin.com/");
        await page.screenshot({
            path: "example.png"
        })
        await page.close();
    } catch (error) {
        console.log("Error:", error.message);
        if (error.response) {
            console.log("Response data:", error.response.data);
        }
    }
};

start_browserProfile();
