Web APIs are essential whether you want to build a web application or incorporate other features. A potent web application development platform for building web APIs that sets them apart from other web-based solutions is ASP.NET Core. It is one of the main ways that the ASP.NET Core platform is implemented.
It is possible to create a variety of web APIs using ASP.NET Core development services that have several uses. It enables programmers to design safe and scalable APIs. The development of ASP.NET Core has various benefits, such as cross-platform compatibility, high performance, and flexibility.
One of the main benefits of using ASP.NET Core for web API development is performance. ASP.NET Core can process more user requests in a second than Node.js and Java Servlet put together.
What is API and Web API?
An Application Programming Interface, or API, gives data interchange and communication between two systems. It establishes guidelines and conventions for the communication between various software systems. To put it simply, API integration services are similar to connecting cables that transfer data between ends. An SDK is a set of tools for creating features and applications, whereas the application programming interface facilitates communication between two systems.
As the name suggests, a web API is an API for web-based interfaces. It serves as a mediator between online apps. The HTTP protocol and other web-based technologies are used by web APIs. Thus, server-client architecture-based online applications are created using web APIs.
What are the types of Web API?
If you want to use ASP.NET to construct a Web API, you should first choose the kind of API you want to build. As stated below, there are several kinds of Web APIs according to their range of applications and accessibility.
Private API
This type of API is limited and not accessible to the general public. Internal or private APIs are designed exclusively for internal use within a company; they are never made available to other users. The purpose of these APIs is to link the systems and software of an organization. For instance, a company may have an API to link its payroll and human resources systems.
Composite API
The purpose of composite APIs is to minimize the round-trip time for each call by combining several API calls into a single call. It speeds up and improves the effectiveness of your online application. You can process several queries in a single database transaction by using this API. When placing an order, an API can do many requests in one call, such as validating payment details, checking inventory, and updating purchase history. This is the finest example of a composite API in the eCommerce industry.
Partner API
One type of API that is only available to particular users is a Partner API. Users who are allowed and trustworthy can access partner APIs. These APIs facilitate cooperation and business-to-business transactions. For instance, in order to function, CRM systems require access to client data. An organization can use a Partner API to let it share this custom data with a third-party service on a selective basis.
Open Source API
An application programming interface that is publicly accessible and available for use in software development by any outside developer or company is called a Public API, often referred to as an Open API or External API. These APIs can be freely integrated with software systems and are not limited to any particular user.
Developers can use a Public API to get particular features and data from third-party software that they can use in their apps. Numerous Open APIs, such as Websocket, GraphQL, Google Translate API, and JSONPlaceholder API, are readily accessible in the public domain.

How to Build Web API with ASP.NET Core
Are you curious about the variety of APIs available in ASP.NET? You can create SOAP, REST, and other kinds of APIs with ASP.NET as it supports a variety of API types.
There are two methods you may utilize to create web APIs for your application: controller-based APIs and minimal APIs. Controllers manage the endpoint logic in a controller-based API. The ControllerBase class has subclasses that are called controllers. Therefore, the controller serves as a conduit for communication between the client (a web application or browser) and the API.
The instructions for creating a basic Web API with ASP.NET Core framework are provided here. Let’s examine these actions.
Step 1: Prerequisites
An IDE or code editor such as Visual Studio Code (VSC) or Visual Studio is required.
You also need to install the web development workload and ASP.NET in the case of Visual Studio.
In addition to Visual Studio Code, the most recent version of C# for VSC and.NET 7 is needed.
Step 2: Start an API project
With Visual Studio, you may select ASP.NET Core Empty from templates to start an API project. In the ensuing window, give your project a name, select.NET 7.0, and deselect “Do not use top-level statements” in the “Additional information” window.
To use Visual Studio Code, open the integrated terminal, switch to the project directory, and type the following command, without quotes: dotnet new web -o “Your API name.” Use the command cd “Your API name” without quotes to get to the project directory. Use the following command code, without quotes: -r../”Your API name.” Select “Yes” when dialog boxes requesting that you upload necessary assets and trust the writers appear.
Step 3: Launch the Program
Open Visual Studio, launch the program by using CTRL+F5, and select the SSL certificate from the pop-up dialog box.
Step 4: Write Code
The primary file where you must place your logic and code is called Program. cs. Make classes in the Program.cs file that corresponds to your needs.
NuGet packages must also be added to support databases and diagnostics. Use the GET, PUT, POST, and DELETE endpoints according to your application’s specifications. Set up JSON serialization to send or store data in JSON format.
Here Are the Examples of ASP.NET Core Web API
For instance, the Book Management API’s function is to let users oversee a library of books. A list of books may be retrieved, information about a particular book can be obtained, and new books can be added to the collection.
API Endpoints: Access Every Book
Approach: GET
Endpoint: /API/books
Gives back a list of every book in the collection.
Get a Book with an ID
Approach: GET
Endpoint: /API/books/{id}
Gets information about a certain book by using its ID.
Add a New Book
Approach: POST
Endpoint: /API/books
Introduces a fresh book to the assortment. The request body contains information about the author, genre, and title.
Application
