For more information, see [Workflow Studio actions and subflow in RPA Hub](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/integrate-applications/rpa-hub-actions.md).\n\nInvoke a flow or a subflow from Workflow Studio by using the InvokeFlow component or InvokeSubFlow component. For more information, see [Use the InvokeFlow component](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/integrate-applications/use-rpahub-flowdesigner-invokeflow.md) and [Use the InvokeSubFlow component](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/integrate-applications/use-rpahub-flowdesigner-invokesubflow.md).\n\nBy default, the flows, subflows, and actions can only be called by the FlowAPI within a server script. Flow and action designers can make individual flows, subflows, or actions available to client calls by enabling the Client callable option during design.\n\nConsider the implications of making a flow or subflow client callable, such as whether it exposes protected data or bypasses validation logic.\n\nRole required: security\\_admin\n\n## Procedure\n\n1.  Navigate to **All** > **Process Automation** > **Workflow Studio**.\n\n2.  Open the flow or subflow that you want to make the client callable on.\n\n3.  In the More Actions menu, select **Manage security**.\n\n4.  Select **Callable by Client API**.\n\n5.  Add the RPA Flow Designer ACL record that you created earlier to the **ACLs** field.\n\n6.  Select **Update**.\n\n\n**Parent Topic:**[Workflow Studio actions and subflow in RPA Hub](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/integrate-applications/rpa-hub-actions.md)\n\n"}}
