Today we will try to make our customized data for web API and push our project on GitHub
Under the project, create a folder call “Entities”.
Right click on “Entities” folder, “Add” -> “new item”, create a new file call Customer.cs
In Customer.cs, we can define the data field for our customer data.
like this
namespace CustomerAPI.Entities
{
public class Customer
{
public int Id { get; set; }
public required string Name { get; set; }
public required string Email { get; set; }
public string? Phone { get; set; }
public string? Address { get; set; }
public string? City { get; set; }
}
}
Next, we need to create a controller file for customer entity
Right click on “Controllers” folder, “Add” -> “Controller”
Then, a pop up window will show up.
Select “API” -> “API Controller - Empty” -> click “Add” button 
Select “API Controller - Empty” -> rename the file to CustomerController.cs -> click “Add” button
Visual Studio code will create a empty controller for us
`CustomerController.cs`
using Microsoft.AspNetCore.Http;
using Microsoft.AspNetCore.Mvc;
namespace CustomerAPI.Controllers
{
[Route("api/[controller]")]
[ApiController]
public class ValuesController : ControllerBase
{
}
}
We can create a get method on it and create a test data for respones.
`CustomerController.cs`
using CustomerAPI.Entities;
using Microsoft.AspNetCore.Http;
using Microsoft.AspNetCore.Mvc;
namespace CustomerAPI.Controllers
{
[Route("api/[controller]")]
[ApiController]
public class CustomerController : ControllerBase
{
[HttpGet]
public async Task<IActionResult> GetCustomers()
{
var customers = new List<Customer>
{
new Customer
{
Id = 1,
Name = "Tony",
Email = "tony@gmail.com",
Phone = "12345678",
Address = "123 home Ave E",
City = "Torondo"
}
};
return Ok(customers);
}
}
}
Ok = status 200
Let see the result on Postman
Yes, we did it.
Assume that we need to push the program on GitHub
Click “Git” on the top left menu -> create a Git repository
-> login GitHub account -> click “Create and Push” button
Wait for the process …
Done.
