How to call the PIWIK API from C# to get the visitor summary?

Hi

How can I call the API from my Asp.Net MVC application to get the data? I downloaded Piwik Analytics .NET API from here GitHub - piwik/piwik-dotnet-api: Official C# implementation of the Piwik Analytics API but I don’t know how should I write the URL and what should I provide as a parameter to the method.

userSettings.setTokenAuth("XYZ");

I have the URL as below:

http://localhost:82/?module=API&method=Referrers.getKeywords&idSite=1&period=range&date=2017-01-01,today&format=json&filter_limit=10

but it is not working.

Please suggest.

Thanks
