[HTTP requests](https://www.mindstick.com/articles/1406/debugging-http-requests-and-http-response) and [responses](https://answers.mindstick.com/qa/116746/how-to-stream-responses-from-ollama-api) are handled in .NET [Core API](https://www.mindstick.com/forum/160547/how-to-pass-multiple-parameters-in-url-dot-net-core-api) controllers using action methods. Action methods are the methods that are called when an HTTP request is received. They are responsible for processing the request and returning a response.

The following is an example of an action method in a .NET Core API [controller](https://www.mindstick.com/blog/273/passing-values-from-controller-to-view-in-asp-dot-net-mvc):

C#

```plaintext
[HttpGet("/products")]
public IActionResult GetProducts() {
  // Get the products from the database.
  var products = productRepository.GetAll();

  // Return the products as a JSON response.
  return Json(products);
}
```

In this example, the `GetProducts()` action method is called when an HTTP GET request is received to the `/products` endpoint. The method first gets the products from the database. Then, it returns the products as a JSON response.

The `HttpGet()` attribute is used to specify that the `GetProducts()` action method can only be called with an HTTP GET request. Other HTTP verbs, such as POST, PUT, and DELETE, can be specified using the `HttpPost`, `HttpPut`, and `HttpDelete` attributes, respectively.

The `IActionResult` return type is used to specify the type of the response that will be returned. In this case, the response is a JSON object. Other response types, such as HTML, XML, and images, can be returned by using the appropriate return type.

The `Json()` method is used to convert the products to a JSON object. The JSON object is then returned as the response.

Here are some additional tips for handling HTTP requests and responses in .NET Core API controllers:

- Use action methods to handle specific HTTP requests. This will help to keep your code organized and easy to maintain.
- Use the appropriate HTTP verb for each action method. This will help to ensure that your API is consistent and easy to use.
- Use the appropriate response type for each action method. This will help to ensure that your API can return the correct data in the correct format.
- Use model binding to bind data from requests to model objects. This can help to simplify the code that you need to write to process requests.
- Use exception handling to gracefully handle errors. This will help to ensure that your API remains available even when errors occur.
