2. If you want to add new activities or modify the existing ones, you should use the HTTP PUT method:

   1. if the activity that you are adding exists, it will be updated.

   2. if the activity that you are adding does not exist, it will be added as a new activity.
      
      Updating via an external system is not allowed only if a specific activity is blocked as Managed by LogiX (it is done by setting a special internal flag in LogiX ). Such blocking occurs automatically when an activity is added or modified through an app that belongs to the LogiX Suite (PackOS or KeepUp).
