Basic File Upload

Upload a file using a signed URL: 
{
  "id": "abc123",

  "action": "FILE_UPLOAD",
  "parameters": {
    "signed_file_url": "{{context.inputs.file_url}}"
  }
}

Notes

  • When using file uploads, include the file URL in your workflow inputs:
  • The file must be accessible via a signed URL (pre-authenticated URL)
  • The file node assumes that the system-level file upload dialog is already opened. Add a click node before the file upload node to trigger this.
  • Common file types like PDFs, images, and documents are supported
  • For multiple file uploads, use a Loop node that loops over an array of file URLs
