Beginner API/Swagger help. C# Rest client generated from online tool.

[Ben Moulton]

Hey, 

Have a set of API already finished api controllers in our main project, I was asked to use Swagger to generate the description of the API, by going to (website).com/swagger/docs/v1 ect. Then put it through the swagger online tool to generate a c# rest client which seemed to work fine. I've just added a simple console application to that project it generated and want to write some examples of consuming those rest api methods. 

My questions are pretty much: 

How do I go about doing the above? 

Is there a best way? 

How do I authenticate these requests? On swagger ui, you just put the bearer - 'apikey' in, not sure how to do similar in the console application. 

But yeah, never worked with web api before or swagger so any help greatly appreciated. 

Thanks!
