Web: Download a File

Use this action to download a file from a public URL and save the file to a field.

How to configure this action

This action uses a URL to download any public file, even files with no extension. Typically, to help find the right URL, look for URLs with the file extension at the end of the URL, for example:


You can find these URLs in most modern browsers by right-clicking a download link and selecting “Copy Link Address”. This copied link will look like the example above and be the URL that points directly at the file.

You can use the same technique to get the URL from a Catalytic file field – right click on a file field output and “Copy Link Address” to copy the download URL.

Fields for this action

  • URL

    • Enter the URL that points directly to the file. The file must be publicly available.
  • Output Field Prefix

    • To help keep output fields organized, choose an output field prefix to add to the beginning of each output field name as this action may output more than one field.
    • The step’s name is used as the prefix by default.

What will this output?

This action may generate multiple fields. To help keep output fields organized, the prefix above will be added to the beginning of each of the output field names, separated by two dashes. Each field will result as:{{output-field-prefix--output-field}}. Learn more
