![]() In addition, public APIs can help build brand awareness and drive traffic to a company’s website or app. By opening up data and functionality to third-party developers, companies can tap into new markets and create new revenue streams. Public APIs can be an important part of a company’s business strategy. For example, Amazon’s eCommerce platform has a public API that allows developers to build shopping apps that access Amazon’s product catalog and checkout process. Public APIs are typically used to expose data and functionality to external partners or to allow third-party developers to build new products and services that complement a company’s existing offerings. The most common classification can be based on their public availability:Ī public API is an interface that allows third-party developers to access and use a company’s data and functionality. Types of APIsĪPIs can be divided into several categories based on their purpose and how they are implemented. It also includes data types for representing geographical coordinates and street addresses.īy using the functions and data types in the API, developers can create applications that make use of the functionality provided by the API without having to understand the underlying implementation details. For example, the Google Maps API includes functions for displaying maps and for retrieving directions. ![]() ![]() The API also includes a number of data types that can be used by the functions. PUT: edit and add to already existing data in a collection Here are five basic request methods that can be made with HTTP APIs: Each function corresponds to a particular task that needs to be performed. By providing access to hidden data and functionality, APIs can open up new opportunities for both developers and users alike.Īn API generally consists of a number of functions or subroutines that can be called by a program. By using an API, developers can save time and effort by reusing existing code rather than having to write their own from scratch.Īlternatively, an API could allow a mobile app to control a piece of hardware, such as a drone or a robotic arm. The Twitter API allows developers to create applications that can send and receive tweets. For example, the Google Maps API allows developers to create applications that can display map data and directions. In other words, it is a way for different applications to communicate with each other.ĪPIs are typically used to access data or functionality that is or isn’t readily available through the user interface. What Is an API (Application Programming Interface)Īn API is a set of programming instructions that allows the software to interact with other software. We'll also discuss when it's appropriate to use each one. In this post, we'll explore the relationship between microservices and APIs and highlight their key differences. In either case, the combination of microservices and APIs can be used to build sophisticated applications that are more resilient and scalable than traditional monolithic architectures. Alternatively, an API might be used to aggregate data from multiple microservices. For example, a microservice may expose an API that allows other services to trigger its functionality. While they serve different purposes, microservices and APIs are often used together to build complex applications. While an API defines how software components should interact, a microservice provides a concrete implementation of those interactions. In contrast, a microservice is a self-contained unit of functionality that can be independently deployed and operated. ![]() An API is a set of rules and protocols that allows software applications to interact with each other. To understand the relationship between microservices and APIs, it's first important to understand the different functions that each one serves. In general, microservices and APIs are two very different things. For example, when you use a mobile app to book a hotel room, the app is likely using an API to communicate with the hotel’s reservation system. On the other hand, APIs (Application Programming Interfaces) provide a way for different software applications to communicate with each other.Īn API allows one application to “expose” its functionality to another application, which can then “consume” that functionality. They also tend to be more scalable and more resilient to failures. For example, microservices can be easier to develop and deploy than monolithic applications. Microservices have become increasingly popular in recent years due to their many advantages. This approach contrasts with the traditional “monolithic” architecture, in which an application is built as a single, large unit. Microservices are a type of software architecture that allows developers to build applications as a collection of small, independent services.
