This workflow reads the data of the last 24 hours from a database and sends it to a tableau server. If the workflow is uploaded to a KNIME Server the execution of this workflow can be triggered via REST from Tableau to update the data in a database. Therefore a URL Action can be used in tableau. Check out the Swagger UI to get the Get Request call you need in the URL Action.
