Playwright automation example

Use Playwright to automate a Multilogin Mimic browser profile with JavaScript or Python. The example below uses your Multilogin API token to start an existing browser profile with Playwright enabled, connects Playwright to the running profile, opens a webpage, and saves a screenshot.

Keep the Multilogin app running while you execute the script. Playwright works with Mimic browser profiles; legacy Stealthfox profiles don't support Playwright.

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

To start automating, check these resources first: Getting started with automation scripting.

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:

npm install axios

Insert your values into the below variables in the script:
1. API_TOKEN: your Multilogin API token
2. folder_id, profile_id: find these values using our guides on DevTools (for GUI) 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. API_TOKEN: your Multilogin API token
2. FOLDER_ID, PROFILE_ID: find these values using our guides on DevTools (for GUI) or Postman

Need the profile ID? You can copy it directly from the Multilogin interface. Learn how: How to copy profile IDs in Multilogin.

Running the script

JavaScript

Launch the app, 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 axios = require('axios');

const HEADERS =  {
  "Content-Type": "application/json",
  "Accept": "application/json",
};
// Insert your automation token in the variable below
const API_TOKEN = "";
// Insert the Folder ID and the Profile ID below
const folder_id = "";
const profile_id = "";

async function start_browserProfile(){
  // Add the automation token to the request headers
  HEADERS.Authorization = 'Bearer ' + API_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();
    // Disconnect Playwright so the script can exit
    await browser.close();
    // Stop the profile
    await axios.get(`https://launcher.mlx.yt:45001/api/v1/profile/stop/p/${profile_id}`, { headers: HEADERS });
  } catch (error) {
    console.log("Error:", error.message);
    if (error.response) {
      console.log("Response data:", error.response.data);
    }
  }
};

start_browserProfile();

Python

Launch the app, 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 .py file with your automation code

Script example

import requests
import time
from playwright.sync_api import sync_playwright

HEADERS = {"Accept": "application/json", "Content-Type": "application/json"}

# TODO: Insert your automation token in the variable below
API_TOKEN = ""
# TODO: Insert the Folder ID and the Profile ID below
FOLDER_ID = ""
PROFILE_ID = ""

HEADERS["Authorization"] = f"Bearer {API_TOKEN}"

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()
            browser.close()
            # Stop the profile
            requests.get(f"https://launcher.mlx.yt:45001/api/v1/profile/stop/p/{PROFILE_ID}", headers=HEADERS)
            print(f"\nProfile {PROFILE_ID} stopped.\n")
