What’s the Difference Between an API vs an SDK?
Not every developer can clearly explain such concepts as SDK and API in non-complex ways for non-professionals in their field. Nevertheless, these terms show up more often than not during software development, and even then, they overlap. In short, SDK and API are used in different ways and for different purposes.
Software Development Kit or SDK contains software tools, libraries, documentation, code samples, processes, and guides that developers need to create applications for different platforms. SDKs often include APIs for developers to interface with, which can be used to create and develop applications. Companies benefit from SDKs available to developers because they easily integrate with their services. SDKs save developers a lot of time by simplifying their work.
Application Programming Interfaces or APIs make the software development process easy by providing an interface for two application programs for seamless and secure data transfer between them. With an API, business apps can open up their data and how it functions to be integrated with other software from partners, external sites, other departments in their company. Most companies, especially tech companies, have built APIs for their customers or internal use.
The key differences between SDK and API:
- An API establishes communication between two applications. SDK is the toolbox and all you need to build applications from scratch.
- An SDK may contain APIs, but APIs cannot contain SDKs.
- SDKs use APIs to make communication between two applications possible. APIs cannot build an application.
- An API is essentially an interface for applications. SDKs are tools used to build applications.
- SDKs are easy to use and faster to integrate. APIs do not have code libraries and are easy to modify.
- APIs deliver a request from one app to another software and deliver a response back to the requesting app. SDKs contain all you need to communicate with another software and all you need to build software.
- Devs always use an SDK to build apps. APIs only come in when there is a need to have external communication with other platforms.
