# Export results to an external system

> Export transaction results to a third-party system via a custom script in the Output activity.

Exporting to an external system requires a custom script. Vantage executes the script specified in the activity's settings. The script can read the transaction's data (including extracted field values and the documents available for export) and send an HTTP request to the external system's API.

<Note>
  The script in an Output activity cannot modify document data (for example, fill in fields). To modify data, use a [Custom activity](/vantage/documentation/skill-designer/process/custom-activity/custom-activity) instead.
</Note>

## Add a custom script

<Steps>
  <Step title="Select the Output activity">
    Select the **Output** activity, and then check **Select additional destination** in the **Actions** pane.
  </Step>

    Select **External system** and click **Settings** to open the script editor.
  </Step>

  <Step title="Write and save the script">
    Configure your script and click **Save**.
  </Step>
</Steps>

For a detailed description of objects you can use in the script, see [Object model](/vantage/documentation/skill-designer/process/custom-activity/object-model).
