Understanding the Use of APIs, Their Functions, and Examples
Understanding the Use of APIs, Their Functions, and Examples | Have you ever considered whether there is an application that can assist programmers in their work without requiring them to create components from scratch? Of course, it can significantly improve the effectiveness and speed of the development process. The API is the solution to this problem.
Many developers and large companies, such as Google and Facebook, currently use and create their own APIs. This article will go into greater detail about functions, types, architectures, how they work, and examples of the API itself.
API stands for application programming interface, and it is used to connect one application to another. The API’s role is to act as an intermediary between different applications, both within and across platforms.
We’ll use the example of buying goods on an online buying and selling platform. You will, of course, access the platform sites of online buying and selling service providers such as e-commerce in order to buy and choose goods and make purchase transactions. So the API here is as an ecommerce or intermediary to connect store or goods owners with consumers.
APIs are also used to communicate with developers who use various programming languages. Developers do not need to supply their own data; instead, they can retrieve data and information from the platform via APIs.
The API can then be used to create a website with various ease-of-use features. For example, if you frequently use WordPress, there must be many features that make integrating an API into a site and its platform easier.
Following that, we’ll talk about the different types of APIs. APIs are classified into four types based on their intended use and access rights. Plunging the world of the world, the world of the world, the world of the world.
1. Exclusive API
The first type of API is a private API, which has access rights that are not generally open and tend to be restricted. Private APIs are typically used on a smaller scale. The API from the back end, for example, to connect information to the front end via the website platform, as well as the API on the application to develop mobile applications.
2. Open API
The second is the inverse of the private API, where this public API can be used by anyone without restriction. It has a very broad range of applications and is open source. The Google Maps API, for example, includes public API access rights. To gain access to data and information sources, simply register on the platform.
3. API Associates
The third is nearly identical to the public API. However, there is a special rule that only users who have registered in advance and have permission to use this interface can use it.
4. API Composite
Finally, it is a type of access right to be able to store data on multiple servers in a single location. Obviously, using this access right provides some convenience in terms of data access speed and flexibility, as well as saving users time.
After determining the type of API, we will proceed to discuss the API’s function. During the implementation process, the API provides numerous conveniences and benefits to every developer. Here are some of its primary functions.
1. Assist with server workloads
The first function of the API is to assist the server with its tasks. Whereas, by utilizing this special interface, the server is relieved of the need to search for and store all data. To obtain data from the origin server, simply call or request an API. The server you use will not be overburdened with heavy tasks if these conditions are met.
2. Create apps more quickly and efficiently.
APIs provide convenience and benefits in terms of application development. To communicate, you do not need to connect two apps. It is only necessary to use APIs to properly establish communication.
The process of integrating and adding features to the application will then be sped up. 's 's 's 's 's. These issues can be resolved quickly and precisely with the help of APIs.
3. Develop useful applications.
Another advantage of using this API is that it produces more functional and complex applications. That is, there is no need to manually enter information when adding it. The same features as the destination application can be displayed simply by using the API.
Consider its application to transportation platforms such as Gojek and Grab. Both platforms do not require the development of a feature to display maps in the application. All data related to regional mapping can be accessed automatically through the platform by simply integrating with the Google Maps API.
Architecture of APIs
APIs, like buildings, have elements that form a foundation so that the buildings built can last a long time. APIs frequently employ at least three types of architectures.
1. RPC (Remote Procedure Call) (Remote Procedure Call)
RPC is one of the technologies used to improve the performance of the client and server sides in terms of communication, and it is simple to implement.
2. REST (Representational State Transfer) (Representational State Transfer)
REST is a popular type of API architecture right now. The benefits of REST do not necessitate extensive coding during the development process. REST uses JSON as its data format, which has the advantage of allowing for faster application performance.
3. SOAP (Simple Object Access Protocol)
The following API architecture is SOAP, with XML as the data format. As a result of using XML, the stored data can be a document.
The distinctions between Web API and Web Service
After learning about APIs, you should understand the distinction between these two terms. So that you can use it according to your application development needs while implementing it.
A web API is a program or interface that connects one application to another on a website-based system. While web services are a type of service that connects different applications via a website-based platform. The distinctions between the two terms are explained below.
- An API is used by all types of web services, but not all types of APIs are used by all types of web services.
- Web services play a role in facilitating network interaction between two devices or applications. Meanwhile, the API facilitates communication between two applications running on different platforms, regardless of whether they require a network.
- APIs can use any architecture, whereas web services can only use three (REST, SOAP, XML-RPC).
- APIs do not require a network to function, whereas web services rely heavily on a network.
The distinctions between API, Rest API, and RESTful API
As previously stated, an API is an application or interface that serves as a link between two applications. Rest APIs are one type of API in terms of architectural design.
The RESTful API, on the other hand, is a REST client that will access data on the REST server within each server. These records or resources will be identified by URLs or global identifiers.
The API’s Operation
Here are some details about how the API works.
- An application accesses an API
- The API makes data-related requests to the server
- The server responds or responds to the API
- The API then returns a response to the application in the form of data or information.
Examples of APIs
The APIs listed below are some of the most commonly used by software developers to improve the performance of their applications.
1. APIs for Google Maps
Google Maps also has an API that can be used to help provide data in the form of maps. As a result, we can access a variety of locations with a very broad coverage area.
By utilizing the features provided by Google Maps, we no longer need to create a map viewer application. All types of location-related information can be displayed accurately by simply using the Google Maps API.
2. The Facebook API
Facebook also has its own API, which includes features for storing user data, posts, games, and payment information. You can make the most of all of these features by incorporating them into your website.
One method is to use this convenience by displaying a Facebook profile on your site. Your complete profile can help to improve your personal branding and make you more visible to visitors.
- API is an application or interface that functions to connect one platform to another using a network or not. APIs are classified into four types based on their access rights: private, public, partner, and composite.
- The advantages of an API include the ability to reduce server workloads, create functional applications, and effectively develop applications.
- At least three popular architectures exist: RPC, SOAP, and REST. There are numerous examples of API use, the most common of which are the Google Maps API and the Facebook API.
