How to download attachment

Questions
1

I am using a form service called Paperform to collect form submissions from my users.

I am using the n8n webhook node to receive the submission data after a user submits a new form.

My form allows users to upload attachments and I receive them as URL’s from Paperform. I want to upload those attachments to Box via n8n, but need a file that I can upload.

It seems like I need to use a node in between the Webhook and Box nodes, but am not sure which one to use.

Here is my current workflow:

{
  "nodes": [
    {
      "parameters": {
        "fileName": "={{$node[\"Webhook\"].json[\"body\"][\"data\"][1][\"value\"][\"name\"]}}",
        "fileContent": "={{$node[\"Webhook\"].json[\"body\"][\"data\"][1][\"value\"][\"url\"]}}",
        "parentId": "134602517010"
      },

You can do that with the HTTP Request Node. You just have to make sure to set “Response Format” to “File”.
