API Funtamentals: Overview
When you start working with APIs—whether designing them, documenting them, or integrating them into applications—it helps to understand the core building blocks that shape every request and response. Although APIs come in many styles, most follow the same fundamental structure: a clear path, a predictable input format, and a consistent output message.In this series, we break down these essential parts into simple, focused articles:1.
Method & Path – How APIs define what operation you’re performing and where you're performing it. 2.
Parameters – Optional or required details that fine-tune your request. 3.
Request Body – Structured data sent with certain HTTP methods (such as POST or PUT). 4.
Responses – What the server returns, including status codes and the data payload.
About the Pet Store API#
The Pet Store is a mock API that simulates a simple online pet management system. Even though it's not a real service, it provides realistic endpoints and data structures that make it a perfect learning tool.The Pet Store API includes common operations such as:Each endpoint demonstrates typical RESTful API concepts, including path parameters, query parameters, JSON request bodies, JSON responses, and standard HTTP status codes.Because the API is intentionally simple, easy to test, and well-documented, it’s ideal for illustrating how modern APIs are structured—especially when learning API design, debugging, or documentation workflows in tools like Apidog.Ready to start?
