VIDEO – HTTP Header Client Secret protected Web API

Watch the video below to see a demo of protecting WebAPI with HTTP header and a Client Secret.    By default, new Web API projects lack any security mechanism and are open to any anonymous user.    Protecting Dot Net methods with an IF() statement condition provides a simple security mechanism to ensure only users who know the Client Secret are able to run the API and execute the method.
