You can connect to cloud data sources in Tableau Prep just like Tableau Desktop, but if you plan to publish flows that connect to cloud data sources and run them on a schedule in your server, you'll need to configure your credentials in Tableau Server or Tableau Online. Some connectors, detailed in the sections below, have different requirements when using them with Tableau Prep Builder. However, Tableau Prep Builder does not support custom certificate-based SSL connections for MySQL-based connectors.
