# 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>

  </Step>
