# tTableauInput Retrieves data from a site on a Tableau server and sends them to the component that follows for transformation. Note that this component only retrieves data from HYPER (hyper) extraction files. It requires Tableau Server 2020.3 (and later versions) and requires that Tableau REST API be enabled on the Tableau server. See [REST API](https://help.tableau.com/current/api/rest_api/en-us/REST/rest_api_requ.htm) for related information. This component is not shipped with your Talend Studio by default. You need to install it using the Feature Manager.
