How to use Refit Client - Call API from DotNet Core [Refit]

🚀 Master API Integration in .NET Core with Refit! Simplify your REST API calls, reduce boilerplate code, and enhance your Blazor applications with this step-by-step tutorial.

In this video, I’ll demonstrate how to use Refit in a .NET Core Application to simplify calling APIs from .NET Core. Refit is a powerful tool that reduces the need for boilerplate code by automatically generating the necessary client code for REST API interactions. By using HttpClient with typed clients, you'll see how Refit handles the implementation, making it easier to work with external APIs. This approach follows .NET Core best practices for structuring your API calls.

We’ll explore how to define an API client interface and implement CRUD operations like GET, POST, PUT, and DELETE. You’ll learn how to use Refit instead of HttpClient for performing these actions, including GET requests to retrieve user data, POST requests to create new users, and DELETE requests to remove users from the system. This ensures that you follow best practices when calling external APIs from C#.

In the demo, we’ll work with a Blazor application that consumes a User API. This API includes methods to call APIs from .NET using Refit, handling CRUD operations such as retrieving all users, fetching a user by ID, creating new users, updating existing users, and deleting users.

Additionally, I’ll demonstrate how to register the Refit client using AddRefitClient, configuring the HttpClient to interact with the API, and setting the base address from configuration. This approach aligns with .NET Core API best practices for working with APIs and handling external data sources efficiently.

What You'll Learn:
- How to call APIs from .NET Core using Refit and HttpClient.
- Implementing Refit HttpClient for CRUD operations with best practices in .NET Core.
- How to efficiently consume external APIs from a DotNet Core application using Refit.

You'll gain valuable insights into API development services by learning how to simplify API integration using Refit in .NET Core. Whether you're a senior API developer or just getting started, mastering Refit can significantly streamline your work and reduce the need for repetitive code. This tutorial also highlights best practices in software application development services, helping you build efficient and scalable APIs. If you're looking to improve your API skills or are involved in software outsourcing and custom API development, this step-by-step guide will be incredibly useful. We’ll also touch on the key role of API programmers in custom web app development, ensuring you have all the tools you need to create seamless and powerful applications.
