Trello - Automated download of attachments

Dear community,

I would like to set up an automation that automatically downloads and saves attachments on a Trello Card and put them in a local folder.

Using the api and token, I assumed I was able to get the download the information from:
https://api.trello.com/1/cards/{CardId}/attachments?key={API_KEY}&token={TOKEN}

Through a normal browser, I am able to access the image or attachments, but when I apply the same logic through ‘Power Automate’, it keeps giving me the ‘unauthorized permission requested’ error. Am I wrong stating Trello is intentionally blocking programmatic requests?

And more importantly, is there a work-around that allows the automated download of attachments if a card is dragged into a specific list?
