Where do I get the SolarWinds API Url and SolarWinds Endpoints, in fetching data or getting data from SolarWinds and display it to a local website? Is there a need to setup first for the said integration?
Have a look over at the OrionSDK Github page https://github.com/solarwinds/OrionSDK. Lots of good information to help you out with getting started there.
These links are great resources to get you started with REST API calls to the SolarWinds Platform.
