If your business doesn't have a LinkedIn Page yet, see how to create a LinkedIn Page for your organization.
Connect LinkedIn to Hookle
Open Hookle app and go to the Profile -> Accounts -> Connect new account.
Select LinkedIn. Log in to your personal LinkedIn account (that should be an admin of your LinkedIn Page). Then accept all desired permissions (LinkedIn will ask for certain permissions) and select the personal profile or page(s) you want to connect to Hookle.
Note: Messages posted to the LinkedIn personal timeline directly through the LinkedIn application, or the statistics of your personal posts, are not available through Hookle!
