This professional-level course provides a thorough grounding in the principles, design, and implementation of Open APIs, enabling software engineers and architects to build, consume, and manage APIs for scalable digital services. Aligned with industry standards such as REST, OpenAPI Specification (OAS), and TM Forum practices, the course enables participants to drive interoperability, accelerate development, and enhance system modularity through well-structured APIs.
Participants will gain hands-on experience designing, testing, and documenting APIs using real tools, and will explore governance strategies to ensure long-term maintainability and security.
Day 1: API-First Design & OpenAPI Specification
Session 1: Introduction to API-First Architecture
Why API-first? Business and technical value
RESTful APIs vs. RPC and GraphQL
OpenAPI Specification (OAS) overview
Session 2: Designing High-Quality APIs
Defining resources, verbs, paths, and payloads
Data modeling, response codes, pagination, and filtering
API usability: naming conventions and error handling
Session 3: Lab – Designing an API with OpenAPI 3.x
Hands-on: Use Swagger Editor to create and document an API
Mocking responses and generating client/server SDKs
API versioning strategies
Day 2: Testing, Security & Lifecycle Management
Session 4: Testing & Simulating APIs
Using Postman, Swagger UI, or Insomnia
Mock servers, contract testing, and integration test design
Performance testing APIs
Session 5: Securing and Publishing APIs
Authentication/authorization mechanisms
Best practices: rate limiting, IP filtering, CORS
Publishing APIs via API gateways (Apigee, Kong, etc.)
Session 6: Lab – Secure and Deploy an Open API
Implement basic authentication & simulate secured endpoints
Generate and validate OpenAPI schema
Explore CI/CD integration and automated API validation
