Did you include your token in the Node-red request?

show us your flow (export it using CTRL+E) and paste into a code block in a reply

Do you have to log in before you get access?

If I try the URL with your token i get ...

e.g. if you opened the link in a different browser (or INCOGNITO mode), do you get asked for a username / password?

Your http request node is set to POST and the api uses GET.  
p.s there is also a space typo in your url.

Good news and bad  
With space removed GET no parse errors, but same as  
for you "no authority"  
In Chrome I did not have to give any authority/password

Possibly because your credentials are cached?

Alternatively, the request might need to have certain headers set.

In chrome, open developer tools (usually F12) then switch to network tab, then refresh the page.  
Inspect the headers sent in the request.  
After that, set the headers you found in chrome into your node-red request (see [cookbook](https://cookbook.nodered.org/http/set-request-header) for how to)
