- **[General guidelines for Workflow Studio flows, subflows, and actions](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/brazil/markdown/build-workflows/workflow-studio/design-considerations-consolidated.md)** Create, run, troubleshoot, and monitor your Workflow Studio components more effectively. Use these guidelines to optimize the performance of your Workflow Studio components. - **[Workflow Studio actions](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/brazil/markdown/build-workflows/workflow-studio/flow-actions.md)** 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://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/brazil/markdown/build-workflows/workflow-studio/flow-logic.md)** 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://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/brazil/markdown/build-workflows/workflow-studio/flow-designer-integrations.md)** Expand the capabilities of Workflow Studio flows with additional subscriptions and spokes. - **[Workflow Studio flow system properties](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/brazil/markdown/build-workflows/workflow-studio/flow-designer-system-properties.md)** Configure how the system processes flows. - **[Workflow Studio flow trigger types](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/brazil/markdown/build-workflows/workflow-studio/flow-triggers.md)** 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://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/brazil/markdown/build-workflows/workflow-studio/flow-troubleshooting-scenarios.md)** 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://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/brazil/markdown/build-workflows/workflow-studio/action-inputs-outputs.md)** 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://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/brazil/markdown/build-workflows/workflow-studio/steps.md)** 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://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/brazil/markdown/build-workflows/workflow-studio/flow-preferences.md)** Enable or disable user preferences for flow to change options available to Workflow Studio. - **[User roles for conversational subflows and actions](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/brazil/markdown/build-workflows/workflow-studio/user-roles-for-conversational-subflows-and-actions.md)** 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://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/brazil/markdown/build-workflows/workflow-studio/supported-input-data-types-for-conversational-subflows-and-actions.md)** 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://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/brazil/markdown/build-workflows/workflow-studio/supported-service-catalog-types.md)** Workflow Studio supports several Service Catalog variable types for both single-row and multi-row variable sets. - **[Transform functions](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/brazil/markdown/build-workflows/workflow-studio/transform-functions.md)** Transform data pill values without the need to write a script. Use transform functions to reformat text, perform mathematical calculations, sanitize potentially unsafe SQL statements, and serialize complex objects to raw XML. - **[Types of flows and when to use them](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/brazil/markdown/build-workflows/workflow-studio/when-to-use-flow-types.md)** A decision matrix and basic definitions help you determine what type of flows to create.
