💬 Description

LinkedInDumper is a Python 3 script that dumps employee data from the LinkedIn social networking platform.

The results contain firstname, lastname, position (title), location and a user's profile link. Only 2 API calls are required to retrieve all employees if the company does not have more than 10 employees. Otherwise, we have to paginate through the API results. With the --email-format CLI flag one can define a Python string format to auto generate email addresses based on the retrieved first and last name.

✨ Requirements

LinkedInDumper talks with the unofficial LinkedIn Voyager API, which requires authentication. Therefore, you must have a valid LinkedIn user account. To keep it simple, LinkedInDumper just expects a cookie value provided by you. Doing it this way, even 2FA protected accounts are supported. Furthermore, you are tasked to provide a LinkedIn company URL to dump employees from.

Retrieving LinkedIn Cookie

1. Sign into www.linkedin.com and retrieve your li_at session cookie value e.g. via developer tools
2. Specify the cookie value either persistently in the python script's variable li_at or temporarily during runtime via the CLI flag --cookie

Retrieving LinkedIn Company URL

1. Search your target company on Google Search or directly on LinkedIn
2. The LinkedIn company URL should look something like this: https://www.linkedin.com/company/apple

Optionally, you can use the CLI parameters --output-json and --output-csv to store the results as JSON or CSV.

💥 Limitations

LinkedIn will allow only the first 1,000 search results to be returned when harvesting contact information. You may also need a LinkedIn premium account when you reached the maximum allowed queries for visiting profiles with your freemium LinkedIn account.
