The specification describes details of exchanged data and defines how the data can be retrieved. APIs enable two distanced entities to talk to each other in a standardized format. There’s an API for that, too, so you don’t have to test every different Android manufacturer’s fingerprint sensor. If you want to embed a web browser to show one or more web pages, for example, you don’t have to program your own web browser from scratch just for your application. You use the WKWebView API to embed a WebKit (Safari) browser object in your application.
- Developers typically use Web APIs to query a server for a specific set of data from that server.
- However, in web service using Java, it is better to consider JSON format since XML format forces developers to transform data operations, which affects the overall poor performance.
- An API may be custom-built for a particular pair of systems, or it may be a shared standard allowing interoperability among many systems.
For example, building a calendar integration for one service provider from scratch can take as long as 12 months for a team of four engineers. With a Calendar API, you can go from an idea to execution in less than two days. Using an API for modular development speeds up the development process and enhances the maintenance and scalability of the application. In some ways, microservices are the next stage in the evolution of SOA. This architectural approach implies developing software as a suite of independent services, called microservices. All of these services are designed to support a single business function.

This convenient feature allows any website to use an API from one of the more popular services for quick authentication. This capability helps save users the time and hassle of setting up a new profile for every web application or new membership. It’s useful to think about API communication in terms of a request and response between a client and server. The application submitting the request is the client, and the server provides the response.
This translates to maximum accessibility for your clients, who will have quick access to all the information they require. The digital world moves at lightning speed, making productivity an absolute necessity. APIs, or Application Programming Interfaces, serve as valuable tools in amplifying developers‘ productivity.
What Are the Different Types of APIs?
A single API can have multiple implementations (or none, being abstract) in the form of different libraries that share the same programming interface. APIs also played a crucial role in inter-process communication (IPC), which allowed different processes running on the same machine to share information. Techniques like shared memory, message queues, and semaphores were used, and they formed the basis for modern IPC.
REST APIs follows a fixed structure, and always return a whole data set for a specified object. If the request is more complex, spanning multiple resources, for example, the client must submit separate requests for each resource. GraphQL is a query language and API runtime that Facebook developed internally in 2012 before it became open source in 2015. GraphQL and REST are both stateless, use a client/server model and use HTTP. GraphQL solves for some limitations of REST, for example, providing the ability to more accurately target wanted resources with a single request.

Apple’s iOS operating system provides a large number of APIs—as every other operating system does—to make this easier on you. The menu provides a list of dishes you can order, along with a description of each dish. When you specify what menu items you want, the restaurant’s kitchen does the work and provides you with some finished dishes. You don’t know exactly how the restaurant prepares that food, and you don’t really need to. Use IBM API Connect to secure and manage enterprise APIs throughout their lifecycles.
There is no visibility on the user interface, meaning APIs exchange data within the computer or application, and appear to the user as a seamless connection. Do you wish you could improve your website projects with a certain feature, but the time and resources are low? Integrating these tools can empower your code and automate your development process. If you’re considering implementing them in your websites, learning whether it’s the right choice is essential.
Enhancing user experience
If the API grants access to valuable digital assets, a business monetizes it by selling access. When AccuWeather (link resides outside ibm.com) started its self-service developer portal to sell a wide range of API packages, it took just 10 months to attract 24,000 developers, selling 11,000 API keys. SOAP and REST represent different approaches to API design, describing rules and standards for how an API should interact with other applications. SOAP is a protocol while REST is a set of constraints that constitute an architectural style.
Microservices, on the other hand, are better suited for smaller and well-partitioned web-based systems because microservices provide significantly more control. Because of a lack of messaging middleware, microservices are unsuitable for complicated applications. SOA is better suited for large, complicated business applications that require integration with numerous applications. Workflow-based systems with a well-defined processing flow, on the other hand, are more challenging to create using SOA standards.
Security and Data Privacy
Servers or devices do not have to fully expose data—APIs enable the sharing of small packets of data, relevant to the specific request. While APIs offer numerous benefits for websites, developers need to recognize some of the challenges that exist with them before deciding to integrate them into their projects. As you can see, there are multiple APIs that serve specific purposes and use cases. When selecting an API for a website, developers should consider the kind of functionality they need, the ease of integration and the reliability of one. This allows the service provider to have flexibility on service offerings. For example, if the infrastructure behind the API involves physical servers at a data center, the service provider can easily switch to virtual servers that run in the cloud.
Above all, most engineers disagree in many aspects, thus slowing down the development process. Lego bricks have a universal way of connecting to each other through what is api in simple words small bumps and holes, which can be considered an API. It provides a simple and structured way to allow pieces to be built together in different ways.
Third-party service providers
Similarly, software can connect together through APIs to create new and interesting mashups. Simply put, when we use an application on our mobile phone, the application connects to the Internet and sends data to a server. The server then retrieves that data, interprets it, performs the necessary actions and sends us the information we wanted in a readable way — all of this happens via API. One internal API can be used for a variety of purposes and can help the entire organization’s business operations run more smoothly.
