how to do API calls of Kentico using ASP.NET MVC?

Question

Hi all, I'm struggling with API calls of Kentico forms using ASP.NET MVC, so that I can use AngularJS to display the return data (JSON format).

Specifically, my client is using Kentico on their server to create data using "Forms" on Kentico and I want to get the records stored in these forms via API calls using ASP.NET MVC. What I'm thinking is that in the general section of the "Forms", I see the "Form code name" showing that "Code name is a string identifier of the object that can be used by developers in API calls or URLs". But it seems to be there's no good example of it on internet. Keep trying to search it but no luck. I also tried to access data directly in SQL Server in which kentico stores the data. But the table's name that Kentico uses in SQL Server to store the data is different from the ones in "Forms" or "Custom tables" in Kentico.

Hope someone can show me how to do it and I really appreciate it. Thanks in advance.
