Your .Net web application will need to use the TokenHelper.cs classes to request an access token. That access token must be sent in the Authorization header.

Unless you have already configured your farm to connect with an O365 tenant, you should use the S2S methods in TokenHelper.

I believe tokenhelper will be useful in SharePoint Online scenarios however, as mentioned we are completely working on SharePoint On-premise.

So, both SharePoint and .Net web application reside on-premise however hosted separately in different envrionments in on-premise.

The S2S methods are for on-prem.
