Seems I've tried everything (or at least ChatGPT has) and nothing seems to have worked. I'm using N8N automation and can get the json with the attachments, but never able to get them to download or actually get the files.
I'm not cool enough to use N8N so I use Make (make.com), but I should be able to help
If you are getting the JSON with the Attachments array already, you are almost there.
You will see array element bytes, which is a base64 encoded string. You can use the convert to file module in N8N to take that string and convert it to binary, which can be downloaded

You would want to first get (retrieve) a list of all the attachments on the card, then choose the ones you want. Or ask your N8N automation to grab them all.
In Trello's API docs, I see "Forge and OAuth2 apps cannot access this REST resource." so hopefully that doesn't apply to your implementation.
