On your dashboard, go to a campaign for which you want to set up Analytics or Adwords. On the Overview tab of a campaign, head to Settings, then Integrations. If you have an existing account, select the account and then choose the appropriate profile. For new accounts, select Add New and a pop up should appear. Make sure you are logged in or you choose the account which contains the GA/Adwords account. Once integrated, you may choose the account on the existing accounts tab and choose the corresponding profile.
