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

```
ALWAYS paste code and flow exports between backticks like this
```

Yes I included valid token

here are exported flows

My apologies I am very new to this.

Do you have to log in before you get access?

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

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

5

I have just tried with incognito and it worked

6

it worked with no password requested

7

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

8

I have tried GET as well as POST
I get the same resulting error

9

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

10

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 for how to)

11

remove the closing /
this worked for me
