Migration Steps

1. Install the Multilogin X Agent

Download and install from your Multilogin X dashboard.

2. Update Authentication

• Replace session-based auth with Bearer Token flow
• Implement token refresh logic (30-minute expiry)
• Consider automation tokens for long-running scripts

3. Update API Endpoints

• Cloud operations: https://api.multilogin.com
• Local operations: https://launcher.mlx.yt:45001

4. Update Automation Scripts

• Selenium: use the port from the start response
• Add Playwright/Puppeteer support as needed
• Update WebDriver connection to use new port format

5. Migrate Profiles

Use the Import/Export API to move profiles.

New Features to Leverage

• Script Runner -- Run Python scripts across multiple profiles
• Object Storage -- Store templates, extensions, and cookies centrally
• Strict Mode -- Choose between quick prototyping and strict validation
• Pre-made Cookies -- Warm up profiles with cookies from target sites
• Extension Management -- Install and manage browser extensions via API
