# Input activity

> Import documents to Vantage from email services, shared folders, and third-party applications via the Vantage API.

The **Input** activity imports documents into Vantage from email services, shared folders, or any third-party application via the Vantage API. Every Process skill must include an **Input** activity.

<Info>
  Vantage creates transactions for files of any format, but a transaction containing any unsupported files completes with errors. For a transaction to succeed, every file in it must be a supported format.
</Info>

By default, the **Input** activity imports documents only via the Vantage API. To enable additional sources, see:

* [Import from a shared folder](/vantage/documentation/skill-designer/process/input-activity/import-shared-folder)
* [Import from an email service](/vantage/documentation/skill-designer/process/input-activity/import-email-service)

Additional sources can be disabled per skill in [Skill Monitor](/vantage/documentation/runtime/skill-monitor/skill-monitor).
