API Intergration For Beginners

About the Event

APIs are the backbone of modern digital products. From fintech platforms and mobile apps to data systems and AI-powered services. This three-week masterclass is carefully designed to help beginners understand APIs from first principles and apply them immediately in applications using TypeScript and SQL.

Participants will be building projects utilizing self-developed APIs and third‑party API integrations. Each session focuses on why an API concept matters, how it is implemented, and where it is used in real production systems.

Additionally, the masterclass also introduces AI-powered APIs, demonstrating how developers can embed intelligent features such as automation, recommendations, and content generation into everyday software products.

By the end of the masterclass, participants will be confident in fetching, validating, storing, and integrating external data, as well as understanding how APIs power intelligent applications.

Learning Objectives

By the end of this masterclass, participants will be able to:

• Clearly explain how APIs work and how systems communicate over the web

• Use HTTP methods, status codes, and headers correctly

• Fetch, process, and validate external data using TypeScript

• Design and expose simple RESTful API endpoints

• Persist and query API data using SQL databases

• Secure APIs using keys, tokens, and basic authentication strategies

• Integrate third-party APIs into practical applications

• Apply error handling and best practices for production-ready integrations

• Understand how AI APIs can enhance modern software products
