An SDK is a set of software development tools that enable developers to create applications for a specific software platform or framework, typically including libraries, code samples, and documentation that simplify the process of integrating an API into an application. Offering an SDK can significantly reduce development time and complexity by providing pre-built code libraries that developers can use to quickly interact with an API, reducing coding and debugging efforts. An SDK also improves the developer experience by providing documentation and code samples, increasing adoption by making it easier for developers to integrate the API into their applications, and facilitating easier maintenance and upgrades, as well as improving security by ensuring secure coding practices are used when interacting with the API.
