API

An API, or an application programming interface, is a set of code-based instructions that enable different software components to communicate and share data. Developers use private, partner, and public APIs to bridge the gaps between small, discrete chunks of code in order to create applications that are powerful, resilient, and able to meet user needs. APIs can be implemented with a wide range of architectures, protocols, and programming languages, which makes a strong API vocabulary essential for anyone who works with software. Use this API glossary to boost your API literacy and learn more about how APIs are designed, developed, deployed, and managed.
