Which one of these would be the easiest to setup server-to-server JWT on? I already have an existing JWT token do I need to setup an entire server just to pass through the token?

I have a requirement use-case to create a client for a web API hosted on another server but cannot figure out how to pass the credentials in .NET Core to the other server, I just need to be able to construct a GET and a POST using C# into a remote server API and build some charting to display the results of the GET.
