# Workflow Studio actions and subflow in RPA Hub

Two-way integration of actions and subflows in Workflow Studio and RPA Hub for a seamless robot execution.

## Flows and actions overview

The flows and actions are built using ServiceNow Workflow Studio, so make sure you’re familiar with the [Building actions in Workflow Studio](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/build-workflows/actions.md) and [Building subflows in Workflow Studio](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/build-workflows/subflows.md) basics.

## Invoke flows or subflow

Invoke the flow or subflow via RPA Desktop Design Studio, Unattended Robot, or Attended Robot. For more information, see the topics listed in [Flow Designer components](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/integrate-applications/flow-designer-components.md).

## Enable the client callable option for a flow or subflow

Enable a client script to trigger an RPA Hub flow or subflow. For more information, see [Enable the client callable option on a flow or subflow in RPA Hub](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/integrate-applications/enable-client-flow-rpa.md).
