I'm trying to use the APIs as per this guide: https://documentation.solarwinds.com/archive/pdf/WHD/WHDAPIGuide.pdf
When I try to authenticate with a username password combination or an API key, I get a 401 error. The same credentials work when I log into my solarwinds helpdesk system.
My college uses this for my helpdesk system and I'm required to create a web interface based on the tickets in the system, for which I need the APIs. Is there some setup that needs to be done by my network administrator?
