How does the LinkedIn import work? Does itogai log into my LinkedIn?

Request your data export from LinkedIn’s own settings. LinkedIn can take up to 24 hours to prepare it. Then upload the .zip file as it arrives, without opening it, or the Connections .csv inside it, in Settings, Connected accounts, under Data sources, LinkedIn, Manually upload. The Connections file becomes your list of first-degree connections in itogai, with the date you connected. itogai never logs into your LinkedIn account, and nothing posts, sends, or connects in it.
