The Start Browser Profile endpoint allows you to launch existing regular browser profiles with automation, using folder_id and profile_id. It is essential for automation users.

➡️ To start a browser profile with Postman, launch Multilogin → open Postman → go to “Launcher” → “Start Browser Profile” → enter folder_id and profile_id → click “Send”. A 200 response means the request succeeded.

Use the optional automation parameter if you need an automation port, or headless_mode if you want to start the browser profile without a visible window.

Before you start

1. Complete all three steps from the article How to set up Multilogin API with Postman, including “Using the bearer token”: they will allow you to sign in correctly
2. Navigate to the “Launcher” folder in your Postman workspace and select Start Browser Profile
3. Enter your values in the request parameters:
   1. folder_id, profile_id: find these values using our guides: DevTools, Postman or CLI
   2. automation: selenium/puppeteer/playwright (specifying this parameter will return the port for automation in the response)
   3. headless_mode: true/false

Running the script

1. Make sure the app is launched, as it makes profile launching possible
2. Click “Send” to execute the request: a “200” status means success

FAQ

Why doesn’t the browser profile start?

Check that Multilogin is running and that your bearer token is still valid. The standard sign-in token expires after 30 minutes. If needed, sign in again, refresh the token, or use an automation token.
