Desktop API port

Looking up API in the forums, I got mixed answers and no docs.

I can see the Manager desktop executable is listening on port 58060 but doing a curl gives a 400 error.

Is there any way to interact with it?

I would like this too.

There are other forum users which use it successfully Search results for 'curl order:latest' - Manager Forum such as API and File Attachments - #4 by MarkLL
