Refit

🚀 Interacting with APIs is easier using Refit

If you’re working with REST APIs in .NET, managing HttpClient and serializing requests manually can be tedious and error-prone.

That’s where Refit comes in — a type-safe REST library for .NET, inspired by Retrofit (from the Android world).

🧠 Why Refit?

With Refit:

✅ No need to manage HttpClient directly
✅ Define interfaces that represent your APIs
✅ Use attributes to set routes, verbs, headers, and query params
✅ Automatically serializes requests and deserializes responses
✅ Strongly typed contracts improve maintainability and reduce bugs

✨ Example

public interface IGitHubApi
{
    [Get("/users/{username}")]
    Task<User> GetUserAsync(string username);
}
 
public class User
{
    public string Login { get; set; }
    public string Name { get; set; }
    public string Company { get; set; }
}

🔧 Setup Refit:

var gitHubApi = RestService.For<IGitHubApi>("https://api.github.com");
 
var user = await gitHubApi.GetUserAsync("octocat");
Console.WriteLine(user.Name);
