Playwright is an open-source automation library designed for testing web applications and automating interactions with web browsers. It offers comprehensive control over browser actions, including navigation, form filling, element clicking, and data extraction from web pages.

In this article, we will provide a simple script that launches a browser profile and connects it with Playwright.

You can automate Mimic browser profiles using Playwright for your web-scrapers. Note that Playwright for Stealthfox is not available in Multilogin X yet.

Before you start

JavaScript

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 Playwright as a dependency for your project:

npm install playwright

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 X account email
2. password: your Multilogin X account password (MD5 encryption is not required)
3. folder_id, profile_id: find these values using our guides on DevTools or Postman

Python

Install the following Python libraries:
1. requests
2. playwright
Install the necessary browser binaries:

playwright install

Insert your values into the below variables in the script:
1. USERNAME: your Multilogin X account email
2. PASSWORD: your Multilogin X account password (MD5 encryption is not required)
3. FOLDER_ID, PROFILE_ID: find these values using our guides on DevTools or Postman

Running the script

JavaScript

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

Script example

const { chromium } = require('playwright');
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 "Playwright" as automation type
  const profileLaunch_URL = `https://launcher.mlx.yt:45001/api/v2/profile/f/${folder_id}/p/${profile_id}/start?automation_type=playwright&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 chromium.connectOverCDP(browserURL,{timeout:10000});
    const context = browser.contexts()[0];
    const page = await context.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();

Run the .py file with your automation code

# TODO: Insert the Folder ID and the Profile ID below
FOLDER_ID = ""
PROFILE_ID = ""

def sign_in() -> str:
    payload = {
        "email": USERNAME,
        "password": hashlib.md5(PASSWORD.encode()).hexdigest(),
    }
    r = requests.post(f"{MLX_BASE}/user/signin", json=payload)
    if r.status_code != 200:
        print(f"\nError during login: {r.text}\n")
    else:
        response = r.json()["data"]
        token = response["token"]
        return token

HEADERS["Authorization"] = f"Bearer {sign_in()}"

def start_profile():
    with sync_playwright() as pw:
        resp = requests.get(
            f"https://launcher.mlx.yt:45001/api/v2/profile/f/{FOLDER_ID}/p/{PROFILE_ID}/start?automation_type=playwright&headless_mode=false",
            headers=HEADERS)
        resp_json = resp.json()
        if resp.status_code != 200:
            print(f"\nError while starting profile: {resp.text}\n")
            return
        else:
            print(f"\nProfile {PROFILE_ID} started.\n")
            browserPort = resp_json["data"]["port"]
            browserURL = f"http://127.0.0.1:{browserPort}"
            # if you prefer to connect with browserWSEndpoint, try to get the webSocketDebuggerUrl by following request
            # response = requests.get(f'{browserURL}/json/version')
            # browser_ws_endpoint = response.json()["webSocketDebuggerUrl"]
            browser = pw.chromium.connect_over_cdp(endpoint_url=browserURL)
            context = browser.contexts[0]
            page = context.new_page()
            page.goto('https://www.multilogin.com')
            time.sleep(5)
            page.screenshot(path='example.png')   
            page.close()
