Trying
The first step is obtaining the ticket. In Postman I can manage using the following:
Then set the cookie in the get request
And I'm able to get the required info.
How to do this in Node-RED?

Export your 2 queries as CURL and I will show you the "node-red" way using requests.
Feel free to sanitise any data (like username/password)

It seems that I can simplify this by creating an API token. The curl command will then be:
`curl -H "Authorization: PBSAPIToken=root@pam!monitoring:xxx" https://192.168.1.150:8007/api2/json/version`
Coverting to JSON I will get:
```auto
{
"url": "https://192.168.1.150:8007/api2/json/version",
"raw_url": "https://192.168.1.150:8007/api2/json/version/",
"method": "get",
"headers": {
"Authorization": "PBSAPIToken=root@pam!monitoring:xxx"
}
}
```
And above is working in Postman.
Like to see how to achieve this in Node-RED.

Try this...
Demo flow (use `CTRL+I` to import)...

I will get:
"RequestError: self signed certificate : [https://192.168.1.150:8007/api2/json/version](https://192.168.1.150:8007/api2/json/version)"

The error is quite self-explanatory... You are attempting an HTTPS request to an IP address and there is no valid certificate. So it fails.
If you look in the manual of the HTTP node:
```auto
rejectUnauthorized
If set to false, allows requests to be made to https sites that use self signed certificates.
```
In the function where msg.url and so on are set, adding a line:
```auto
msg.rejectUnauthorized = false;
```
should do the trick.

Thnx, I had a look before at this but the post I found had a slightly different solution that did not do the job.
Thanks a lot for your help. It turned out that I should not use the HTTP nodes but just write a function.
