# API Design & Development

> Design and build APIs through mentor-led sessions focused on practical scenarios and real integration use cases. Learn REST principles, documentation, security, and testing for production-ready APIs.

## Overview

API Design & Development equips learners with the skills needed to design, build, and maintain high-quality APIs used in modern software systems. This mentor-led course focuses on practical scenarios, helping participants understand how APIs enable communication between applications in real-world environments.

Participants will explore RESTful design principles, API versioning strategies, authentication patterns, and error handling. The course also introduces OpenAPI/Swagger for documentation and covers testing approaches to ensure reliability and maintainability.

By the end of the programme, learners will have designed and implemented well-structured APIs aligned with industry best practices. The course is aligned with real-world backend development expectations and prepares learners for roles involving system integration and service architecture.
