You will need to construct the different parameters within your Server URL. You will need both the _site and _workbooks tables.
From here you need the following fields, which will feed dynamically into the URL action.
In the URL action, put the following string:
https://tableauservername//#/site/<Url Namespace>/workbooks/<Id ( Workbooks)>
Let me know if this solves your problem.
