asp.net web api - How to name api routing on a webhost sub folder -

I have always thought where the API controllers did not get to the physical path. The reason I ask is that I created a folder example.com/testing and there is a website example.com uploading my project to it. When I took part I found errors saying that no API controller was found. So I changed the API / API clients / test / API / API clients. After this it worked, not the actual posting of any new record. It detects and retrieves all records of the database. But it does not seem to be what I really have to do? I have a domain with WinHost and default published folder example.com/myApp I'm looking at this incorrectly?

To manage the request where you do not know the root path, you can use (asp. In this way, ~ -Doctor:

  ~ / api / apiCustomers  

~ will be replaced by root (i.e. / api / and / test / API / apiCustomers for apiCustomers prod for your testing environment)
