APIs Explained for Non-Engineers

Summary

An API is a contract that lets two systems exchange data in a predictable format — understanding this at a conceptual level lets a BA scope integration requirements without needing to write code.

• 1Learn to explain what an API does using a simple analogy (like a restaurant waiter taking an order).
• 2Read a simple API's documentation and identify what data it sends and receives.
• 3Practice writing an integration requirement that references an API without over-specifying implementation.
