APIs are an essential part of modern software ecosystems. They provide a convenient way to integrate third-party developers into your software without having to distribute the integration code yourself.

With this in mind, choosing which API protocol to use can be overwhelming. Which one is right for your project? Are there any downsides to using it?Let's examine this topic in more detail and find out when and how you should use them.

What is an API? 
API
is a protocol that allows developers to easily integrate it into their software. It defines the types of information they can access and how they should interact with your application.

There are many different types of APIs.The most popular are HTTP API, SOAP API and REST API.
The HTTP
API is an interface that uses standard request methods to communicate, such as B. GET, POST, PUT and DELETE. This means that the data is delivered to your application in a consistent form.

SOAP API uses XML over HTTP to send requests and responses. This allows for very flexible data transfer between systems, as well as advanced features like caching and authentication (more on that later).
The
RESTful APIs use a separate URL endpoint to retrieve data from the system in JSON format using HTTP verbs such as GET, POST, PUT, or DELETE.

HTTP based API
The HTTP-based API is the most common of the three available. As such, it is commonly used in web and mobile applications, and is also the standard protocol for desktop applications. You can use this type of API to integrate with your software via REST APIs or OAuth2 authentication. The main disadvantage of using an HTTP-based API is that you have to implement a lot of integration code yourself since there are no libraries that work with all systems.However, they provide a convenient way for developers to communicate with the software if they don't want to implement their own embed code.

RESTful APIs API
RESTful protocol is a popular standard that you can use to build dynamic and modular websites. It offers a resource-oriented architecture and aims to be a lightweight system that can be used on devices with low power consumption and limited storage space.

The RESTful API protocol has several advantages, including:

Easy creation of new resource endpoints since HTTP standards are used
Modern languages ​​like JavaScript and Ruby are easier to integrate
supports multiple data types and data structures, which means you can use different programming languages ​​without having to convert data to another format
Use the HTTP standard so that other clients can easily download your API GraphQL based
API The
GraphQL-based API is a RESTful API developed by Facebook in 2016. The GraphQL-based API was originally designed to help developers create apps that better integrate with the Facebook platform. .�

This solution allows you to create your own schema and type system without having API maintainers for social media platforms like Facebook or Instagram. This approach allows for more flexibility and creativity because you can design your application based on your needs, not platform limitations.

What is the difference between HTTP and REST?
There are two main API protocols that you can use in your project. One of them is HTTP, which stands for Hypertext Transfer Protocol.This protocol was originally developed in the early 1990s and has been around since 2000. REST stands for Representational State Transfer and was developed by Roy Fielding in 2000-2001.
The main difference between the two is that HTTP uses a series of messages to load and transfer data, while REST uses a single request to retrieve specific data, usually over an object identifier called a resource identifier. There are also other differences, e.g. B. how errors are handled, what type of content they allow, etc.

Which one to choose?Well, it depends on the specific needs of the project. If you need more flexibility use REST and if you need a lot of control use HTTP (Hypertext Transfer Protocol).

Benefits of using the GraphQL-based API
GraphQL is a popular API protocol. With this protocol you can request data from the backend as a request, which is then sent back in JSON format. This means you can define the structure of your application with less complexity than with today's APIs.

This also means that you don't have to worry about what information the server has in the backend. GraphQL makes it easier for developers to create functions from your application because they can request exactly what they need, no more than they need.

Another benefit of GraphQL is that it's an open-source protocol, which means it's much easier to integrate with other languages ​​than other proprietary APIs like AWS Lambda and Google Cloud Functions.
Finally, GraphQL is easy to program because it can be used with any standard JavaScript framework. This means that developers who are new or unfamiliar with API development will not be surprised by GraphQL and can quickly learn how it works.

disadvantages of using a GraphQL-based API
The main benefit of using a GraphQL-based API is that you don't need a separate server-side language. This means that the GraphQL server can be implemented in any programming language.However, the main disadvantage is that it can take longer to implement than an RPC-based API or a RESTful API.

If you are unsure which protocol to use, consult with developers who are familiar with both APIs.

There are many different API protocols, so deciding which one to use can be confusing. This guide provides the information you need to choose the right API protocol for your project.

To decide which API protocol to use, you need to answer these six questions:

What is the purpose of my project?
What data is my API used for?
What is my deadline?
What is my budget?
Will my API be public or should it remain private?
How important is API security?
