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

## Flows and actions overview {#rpa-hub-actions__section_gqr_gbj_lrb}

The flows and actions are built using ServiceNow
Workflow Studio, so make sure you're familiar with the [Building actions in Workflow Studio](https://www.servicenow.com/docs/access?context=actions&version=australia&pubname=australia-build-workflows&ft:locale=en-US) and [Building subflows in Workflow Studio](https://www.servicenow.com/docs/access?context=subflows&version=australia&pubname=australia-build-workflows&ft:locale=en-US) basics.

## Invoke flows or subflow {#rpa-hub-actions__section_aft_5gv_ksb}

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://www.servicenow.com/docs/lMEN07wx9TxJ56G1mOQBRw "The Flow Designer components let you invoke flows, subflows, and actions from Workflow Studio and use them as part of a workflow. You can also use these components to determine a flow's output or execution status.").

## Enable the client callable option for a flow or subflow {#rpa-hub-actions__section_cy1_myp_w1c}

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://www.servicenow.com/docs/E0_kEvn8PuKzBQNfxystzw "Enable a client script to trigger an RPA Hub flow or subflow.").

To automatically migrate the package attachment (automation zip file) from a lower (non-production) to a higher (production) environment. For more information about importing a package version attachment in RPA Hub, see [Import a package version attachment in RPA Hub](https://www.servicenow.com/docs/PmleBVKFvouBmOCMu0rQDw "Import package version attachments automatically instead of manually uploading a package version attachment, by selecting the Import Attachment button on a package version."). | * Email: Email * Package Version: Record {#rpa-hub-actions__ul_qjh_wjq_w1c} | After the attachment is uploaded successfully or if an error occurs while uploading the attachment, an email notification (if email is provided as an input) is sent to the user who performs this import attachment action. |
| Start Process Subflow | Triggers a specific bot process in RPA Hub. Returns process job details. | * Process Name: Record * Robots: Array\[String\] Ignore an entry in this field if a robot pool is assigned to the bot process.
