Use these guidelines to optimize the performance of your Workflow Studio components. * **[Workflow Studio actions](https://www.servicenow.com/docs/j4UlXNk0HLdNsTVksEOwFA)** Actions can be added to any flow, enabling process analysts to automate ServiceNow AI Platform features without having to write code. * **[Workflow Studio flow logic](https://www.servicenow.com/docs/vQHNzqE_e43Ets_2E9QuRg)** Enable flows and subflows to specify conditional or repeated actions. Combine the elements of flow logic to create workflows in a graphical interface with little or no scripting. * **[Workflow Studio flow integrations](https://www.servicenow.com/docs/~EhWrULc_yY4GtNUQg~IlA)** Expand the capabilities of Workflow Studio flows with additional subscriptions and spokes. * **[Workflow Studio flow system properties](https://www.servicenow.com/docs/ZiSrhpPWhOmNQ3gHe2io5A)** Configure how the system processes flows. * **[Workflow Studio flow trigger types](https://www.servicenow.com/docs/9byv16g7v9bD98vugUnTBw)** Each trigger type defines when a flow starts and the starting data available to it. There are triggers for record operations, dates, and application operations. * **[Flow troubleshooting scenarios](https://www.servicenow.com/docs/HJ55WZO0ycNRkK2A~b_Q0w)** Learn how the Flow Troubleshooting Agent addresses common flow execution errors and troubleshooting scenarios you may encounter when designing and running flows. * **[Workflow Studio input and output data variables](https://www.servicenow.com/docs/yLOTm7VwCQT5OxQXwGypsg)** Actions and subflows use variables to store input and output data. The variable data type determines what kind of data it stores and its advanced configuration options. * **[Workflow Studio steps](https://www.servicenow.com/docs/dviCKJNFcqBKbmUXvLoeCA)** A step performs a single operation in an action. You can use Workflow Studio to add steps to a custom action. * **[User preferences for flows](https://www.servicenow.com/docs/xQCwcosu6OyJJQR2b8em3w)** Enable or disable user preferences for flow to change options available to Workflow Studio. * **[User roles for conversational subflows and actions](https://www.servicenow.com/docs/N83CXnyVMQ68~gmLhkayOA)** Provide personnel with one or more user roles to grant them access to conversational subflows and actions. * **[Supported input data types for conversational subflows and actions](https://www.servicenow.com/docs/sQjk79TxNN8a5e5CcdeOxw)** Conversational subflows and actions support a limited number of input data types. To be compatible with conversational interfaces, an action or a subflow must only include inputs that use supported data types. * **[Supported Service Catalog variable types](https://www.servicenow.com/docs/T~xhefDlKZPYWegl7X6cLg)** Workflow Studio supports several Service Catalog variable types for both single-row and multi-row variable sets. * **[Transform functions](https://www.servicenow.com/docs/0yvUhOjz_OgF2QP6A9ygeA)** Transform data pill values without the need to write a script.
