# 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>

  <Step title="Choose External system">
    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).
