If you use a third-party analytics platform such as Chartable with POST, you can manage your tracking URL within the POST application.
Once your account is set up, and you have your tracking URL from the third-party account, log into POST and navigate to the SETTINGS page.
From the settings page, click TRACKING URLs in the left-hand settings column.
Select the appropriate show from the drop-down menu in step 1 and then paste in your tracking URL in step 2. Click "Apply" to save your changes. And you're done!
