Phantombuster allows you to automate many actions on several social networks and even by email. To use it, you must already select the support, the desired action and then obtain your LinkedIn connection cookie:
Connect to your LinkedIn profile; Right-click then click on “Inspect”; A window opens on the right of your screen. Go to “Application” then “Cookies”; Find the LinkedIn cookie and click on it; In the spreadsheet that appears, find the value “li_at” in the “Name” column. Copy this sequence of letters. Paste it into the Phantombuster cookie field and voila, your phantom is ready to run!
