Within your CASTANET account, the page at the bottom of the menu, shaped like a lock, holds your LinkedIn credentials. You may enter and/or update your credentials here, however, please make sure that the credentials you enter match your LinkedIn profile exactly. At the top of the Credentials page, a notification will tell you if the credentials are connected and working properly (or not). Don’t forget to use the blue “Save credentials” button at the bottom when you are finished adding or updating the credentials.
