REST/SOAP/RPC API Contracts API Security Versioning & Lifecycle DevOps/CI-CD Fit
Fundamentals of API Development Hands-on labs included

Overview

This course teaches the fundamentals of API design and development: what APIs are and why they matter, how REST/SOAP/RPC protocols differ, how to write and document API contracts, how to manage an API's lifecycle and secure it, and how APIs fit into a modern DevOps ecosystem.

Who Is This For

  • Software developers who need the fundamentals of API design and development

Prerequisites

  • Basic Java familiarity (classes, interfaces, collections)
  • IntelliJ, a JDK, and Postman installed before class
  • No prior API design experience required

Learning Path

  • Explain the purpose of APIs and define key terms in API development
  • Differentiate between API types and API protocols
  • Build contracts into APIs and describe RESTful standards

  • Discuss the API lifecycle and design a non-breaking versioning strategy
  • Understand why security matters for APIs and configure basic security rules
  • Describe how APIs fit into a DevOps/CI/CD ecosystem

By the end: You can design, secure, and manage the lifecycle of production APIs.
