How to turn a file into a download link

To get a link for a file in a scenario or workflow, send it to the 1001fx function uploadasset – from Make, n8n or the 1001fx app. It stores the file and returns a download URL, which you can pass to modules and APIs that expect a URL instead of a file. The file is deleted automatically at the end of the next day.

Without building anything: connect your assistant to 1001fx once and ask for the result in your own words.

    Get the answer

    Pass files as links. File results come back as a temporary download link. Each run is charged like an API call.

Tips

  • The link works until the end of the next day: use it in the same run, not for permanent storage.
  • If an API wants the file content as text instead of a link, use asset2base64.
