What is SDK?
An SDK (Software Development Kit) is a bundle of tools, libraries, documentation, and sometimes a compiler or emulator that lets developers build applications for a specific platform, service, or hardware target. Unlike a plain API client library, an SDK is typically a fuller toolkit — for example, the Android SDK includes build tools and emulators, not just API bindings.
Example
The Stripe SDK provides pre-built client libraries so you don't hand-craft raw HTTP requests to their payment API.
