Web API Advantages and Disadvantages

A Web API is a web-based application programming interface. A Browser API may be used to enhance a web browser’s capabilities. A Server API may be used to enhance a web server’s capabilities. Using a web API framework, it is simple to develop services that execute on several entities. Thus, web API enables developers to create ASP.NET applications that are interoperable with almost every browser and device.

In the simplest terms, a web API operates when a client (such as a Web browser) sends an HTTP request to a Web server. The server evaluates the request to ascertain the user's intent. It then delivers data in some format (such as a page), which the client then studies to ascertain the user's intent.

Advantages of WEB APIs

The following are significant advantages of using API services:

The WEB API is the optimal choice for developing resource-oriented services that use HTTP/Restful and integrate nicely with MVC-based applications. For more specific, lighter-weight services, a WEB API is a preferable solution. The WEB API is compatible with any text format, including XML, and is far quicker than the Windows Communication Foundation (WCF). WCF was developed to facilitate the development of SOAP-based services and interfaces. Because WCF is SOAP-based, which means it communicates using a standard XML structure through HTTP, it may result in more unsatisfactory performance.
The WEB API may be used to develop full-featured REST services. WEB API does not need data contracts or WCF-level customizations. If the speed of development and performance are essential to you, WEB API is a better alternative than WCF.
APIs support any media format. The service interface of an API is composed of URL patterns and HTTP methods. Their caching approach is included within the application control HTTP Prefer. Similarly, APIs manage failures via the use of HTTP status codes, filters, and exceptions.
Web APIs may be used to access non-SOAP-based services such as XML or JSON strings. Additionally, they support all HTTP capabilities (like Get, Put, Post, Delete for CRUD operations). Web APIs have been extensively used by clients such as browsers and mobile devices. They may be self-hosted or IIS-hosted. Routing, OData, model binding, and validations are all supported by web APIs.
The API can perform typical CRUD (Create Read Update Delete) operations through the HTTP verbs GET, PUT, POST, and DELETE. The API enables you to expose service data to the browser. It is built on HTTP, which is simple to design and exposes data in a REST-full manner.

Disadvantages of API

The following are significant disadvantages of using API services:

Expense: Providing an API is costly in terms of development time, ongoing maintenance, documentation for the API on your website, and support for API users.
Security: By incorporating an API, you expand your website's attack surface.
You may be dissatisfied with the outcome or decide to pivot your firm. It is not always straightforward to forecast how your API will be utilized. Withdrawing an API might be a terrible experience for consumers if you chose to do so.
Developing APIs is a lengthy procedure that requires a set size. Programming skills are required to construct APIs. It can crash when testing the API. The expense of maintenance is significant.

REST API

A REST API (also referred to as a RESTful API) is a kind of application programming interface (API or web API) that adheres to the REST architectural style’s limitations and enables interaction with RESTful web services. The term “REST” refers to representational state transfer. Web Service APIs are a subset of REST APIs. A REST API is a kind of design for developing Web Service APIs that is standardized. One of the prerequisites for a REST API to be a REST API is making requests over a network using HTTP methods.

Advantages of REST API

You already have the code. Simply connect and play. Your development time is significantly decreased.
If you're utilizing standard APIs, the chances are that many other people are as well. As a result, your codebase is reasonably portable, which might be advantageous at times.
Standard APIs often provide a large amount of free community support if you need assistance. If you develop all of your code, you're very much on your own when it comes to debugging.

Disadvantages of REST API

Given that you are using another developer's code, you must comprehend the developer's structure and assumptions.
Suppose you need to edit existing code to add some more functionality. In that case, you may have to dig through layers and layers of files to locate the line that requires modification. It may get rather irritating at times.
APIs are often used to refer to callable services and may be thought of as an evolution of SOA as an architectural approach. As their name indicates, Services flourish in conditions where they can be contacted. They are less well adapted to highly automated machine-to-machine applications (A2A and B2B/EDI). APIs, in particular, are insufficient to replace established interfaces such as HL7 or X12.
