Key Features and Use Cases - (Web API)

Web API is a framework for building web APIs that can be used by a wide range of devices and platforms. In this tutorial, we'll discuss the key features and use cases of Web API.

Syntax

There is no specific syntax for using Web API, as it is a framework rather than a specific technology.

Example

Here is an example of a simple Web API controller that returns some data in JSON format:

using Microsoft.AspNetCore.Mvc;

[ApiController]
[Route("[controller]")]
public class MyController : ControllerBase
{
    [HttpGet]
    public IActionResult Get()
    {
        return Ok(new { message = "Hello, World!" });
    }
}

In this example, we've created a simple Web API controller that returns a JSON response with a message.
