Difference Between SDK and API?

SDK vs API, are two common core tools for developers to ease their application tasks. API stands for application programming interface refers to the programming guidelines and standards for gaining access to a database or web tool.

For instance, a software company might give away its API to other software developers privately or publicly so that they can make products that use its service. SDK stands for the software development kit also known as a devkit.

It is a collection of tools for building software for a specific platform. These tools include building blocks, debuggers, and frequently a framework or collection of code libraries, such as a set of routines for an operating system (OS).

What is SDK?

SDK (Software Development Kit) is a collection of software development tools, libraries, and documentation that enables developers to create applications for a specific platform or operating system. Examples – Amazon Web Services SDK, Microsoft Azure SDK, Google Cloud SDK, and much more.

It provides a comprehensive set of resources and pre-built components, such as user interface elements, database connectors, and debugging tools. SDKs are generally platform-specific and encompass a wider range of functionalities.

Uses of SDK

SDK has many uses for developers in various industries such as in mobile app development. It plays a crucial role in app development in Android or iOS. SDK provides a kit for building apps that run on devices including API for accessing network connectivity and user interface.

Programming language-specific software development kits (SDKs), such as the JSON and Java Developer Kit (JDK), are used to develop programs in those languages in a streamlined and uniform manner.

To produce dynamic and captivating experiences, SDKs are widely employed in the game development industry. Game development SDKs offer a variety of resources, frameworks, and tools for creating games on various platforms.

Benefits of SDK

Access to the instructions and component pieces needed to construct software: Consider a retail SDK, which includes all the features you could want in your app (such as favorites, cart, save for later, checkout, etc.).
Integrations that go more quickly and smoothly are made possible by SDKs, which also make it easier to acquire necessary information.
shorter product development cycle and more effective product deployment and market entry Because an SDK is designed to educate, equip, and offer development shortcuts, developers may concentrate on creating the desired product.
Built-in support and expertise eliminate the need to pay outside help or look for solutions because SDKs already have pre-built code that has been produced by experts and support documentation that is supplied.

What is an API?

API (Application Programming Interface) is a set of protocols, tools, and methods that define how software components should interact with each other. For example – NewsAPI, Google Maps API, PayPal API, and more.

It acts as an intermediary layer between different software applications, enabling them to exchange data and functionality seamlessly. APIs have a narrower scope and primarily focus on facilitating communication and integration between different software systems.

Uses of API

SDK and API have different use cases but SDK has at least one API. APIs uses are the most common and we may use them on a daily basis such as:

Maps: It is common these days to use maps to navigate from one location to another.
Payment: Payment APIs such as Paytm, PayPal, and UPI have become common uses these days, especially for e-commerce.
Weather: It provides users the option to get weather forecasts and updates from any location.

Benefits of API

Integrating many software programs to improve the overall product offering.
automating the development cycle to make it shorter.
lowering the amount of resources that would otherwise need to be set aside for internal tasks.
delivering new services to customers as effectively as possible.

Major Differences between SDK and API

	Purpose	Functionality
API	APIs are intended to provide a standardized interface for software components to communicate and interact with each other. They enable developers to integrate their applications with external services, libraries, or platforms. APIs target developers who want to leverage the functionality and data provided by external systems or services within their applications.	APIs focus on defining the methods, protocols, and data structures that enable communication between different software components. They provide a standardized set of functions or endpoints that developers can use to access specific services, retrieve data, or perform actions within external systems. APIs primarily expose functionality or data, rather than providing a complete development environment.
SDK	SDKs are primarily designed to assist developers in building applications for a specific platform. They provide a comprehensive development environment that includes tools, libraries, and resources specific to that platform. SDKs target developers who want to create applications that utilize the platform's capabilities efficiently.	SDKs offer a wide range of tools and components that streamline the development process. They include libraries, frameworks, sample code, and documentation to facilitate various aspects of application development. SDKs often provide specific features and functionalities unique to the platform, allowing developers to leverage platform-specific capabilities effectively.

What to Choose Between API vs SDK?

Both SDK and API go hand in hand, but as mentioned above SDK contains API. API defines how the platform works together and SDKs are complete tool kits. In summary, SDK and API have different purposes, scopes, and target audiences.

SDKs provide a comprehensive development environment for building applications on a specific platform, offering pre-built components and tools. APIs, on the other hand, facilitate communication and integration between different software.
