Selenium browser automation

Browser automation allows you to automate tasks inside Multilogin browser profiles, from creating simple automation scripts to complex web crawlers that search, collect and interact with web data.

Multilogin browser automation is based on the Selenium WebDriver.

In the usual scenario, if you are running Selenium code, you would first connect to the Firefox (Gecko) or Chrome driver and then set desired capabilities. When using Multilogin with your Selenium code, you do not need to do that.

Instead, you use the Remote Web Driver to connect to the Multilogin application or browser profile via the local port and set desired capabilities to execute Selenium commands in a pre-defined browser profile.

Supported languages

Because the Selenium framework offers a variety of language bindings, Multilogin automation can be also run on multiple coding languages. However, currently, technical support is only provided for Java and Python language.

Selenium with Multilogin

Multilogin port allocation

You need to predefine the application port in order to utilize Selenium automation.

  1. Go to the C:\Users\%username%\.multiloginapp.com directory and open the app.properties file using any text editor
  2. Add the following string to the file: multiloginapp.port=[PORT_NUMBER]
The port number has to be in the range of 10000 to 49151.
  1. Save the app.properties file

Thereafter, you will be able to refer to the Multilogin application through this port.

For more detailed instructions on how to complete these steps on different operating systems, check this guide.

Java example

import org.junit.Assert;
import org.openqa.selenium.firefox.FirefoxOptions;
import org.openqa.selenium.remote.RemoteWebDriver;

import org.json.JSONObject;
import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.net.HttpURLConnection;
import java.net.URL;

public class BrowserProfile {
public static void main(String[] args) throws Exception {
BrowserProfile bp = new BrowserProfile();
//TODO replace with existing profile ID. Define the ID of the browser profile, where the code will be executed.
String profileId = "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx";

//Define DesiredCapabilities
DesiredCapabilities dc = new DesiredCapabilities();

//Instantiate the Remote Web Driver to connect to the browser profile launched by startProfile method
RemoteWebDriver driver = new RemoteWebDriver(new URL(bp.startProfile(profileId)), dc);

//Perform automation
driver.get("https://multilogin.com/");
Assert.assertEquals("Multilogin | Scale Fast With 1000s Of Profiles",driver.getTitle());
driver.quit();
}

private String startProfile(String profileId) throws Exception {
/*Send GET request to start the browser profile by profileId. Returns response in the following format:
'{"status":"OK","value":"http://127.0.0.1:XXXXX"}', where XXXXX is the localhost port on which browser profile is
launched. Please make sure that you have Multilogin listening port set to 35000. Otherwise please change the port
value in the url string*/
String url = "http://127.0.0.1:35000/api/v1/profile/start?automation=true&profileId=" + profileId;

URL obj = new URL(url);
HttpURLConnection con = (HttpURLConnection) obj.openConnection();

con.setRequestMethod("GET");

BufferedReader in = new BufferedReader(
new InputStreamReader(con.getInputStream()));
String inputLine;
StringBuffer response = new StringBuffer();

while ((inputLine = in.readLine()) != null) {
response.append(inputLine);
}
in.close();

//Get JSON text from the response and return the value by key "value"
JSONObject jsonResponse = new JSONObject(response.toString());
return jsonResponse.getString("value");
}
}

Python example

from selenium import webdriver
import requests

#TODO replace with existing profile ID. Define the ID of the browser profile, where the code will be executed.
mla_profile_id = 'xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx'

mla_url = 'http://127.0.0.1:35000/api/v1/profile/start?automation=true&profileId='+mla_profile_id

"""

"""
resp = requests.get(mla_url)

json = resp.json()
print(json)

#Instantiate the Remote Web Driver to connect to the browser profile launched by previous GET request
driver = webdriver.Remote(command_executor=json['value'])

#Perform automation
driver.get('https://multilogin.com/')
print(driver.title)
driver.quit()
