About the APIs and Web Services: Building, Consuming, and Securing Modern Integrations Course

APIs and Web Services: Building, Consuming, and Securing Modern Integrations is a practical course for anyone who wants to understand how applications connect, exchange data, and work together across the web. Designed for Software Development learners, it gives you a clear, A practical, end-to-end guide to how applications communicate across the web, APIs and Web Services so you can build stronger integrations with confidence.

Build Strong API Integration Skills for Modern Software Development

  • Learn the foundations of APIs, web services, clients, and servers in a clear, structured way
  • Understand HTTP, requests, responses, headers, and data formats that power real-world integrations
  • Design better REST APIs with thoughtful endpoints, methods, filtering, pagination, and error handling
  • Apply security, testing, documentation, versioning, and performance best practices to production-ready APIs

A practical, end-to-end guide to how applications communicate across the web, APIs and Web Services.

This course starts with the core ideas behind APIs in modern software, then builds step by step into the protocols, design patterns, and implementation practices used by professional developers. You will learn how clients and servers interact, how HTTP supports communication, and how JSON, XML, and other formats shape the data that moves between systems.

As you progress, you will explore REST principles, resource design, endpoint selection, status codes, and error handling so you can create integrations that are reliable and easy to maintain. The course also covers security essentials such as authentication, authorization, API keys, tokens, and OAuth concepts, helping you understand how to protect access to services and data.

You will also learn how to consume APIs in applications, test them with tools and automation, document them for other developers, and manage their lifecycle through versioning and backward compatibility. Topics like rate limits, caching, and performance basics round out the course so you can think beyond simple requests and responses and toward scalable, maintainable systems.

By the end of this course, you will be able to approach API work with a stronger technical foundation, better judgment, and practical skills you can use in real Software Development projects. You will move from simply using integrations to building, evaluating, and securing them with confidence.

This lesson explains the basic language of web communication: requests , responses , and headers . Students learn how a client asks for data or actions, how a server replies, and how headers add criti…

Data Exchange

1 lesson

Lesson 5: Data Formats: JSON, XML, and More

19 min
APIs move data between systems, but that data has to be represented in a format both sides can understand. In this lesson, you’ll learn how JSON and XML structure information, why JSON is the default …

API Design

3 lessons

Lesson 6: REST Principles and Resource Design

22 min
This lesson explains the core REST principles that make APIs predictable, scalable, and easy to use. You will learn how to think in terms of resources , choose sensible URI patterns, map HTTP methods …

Lesson 7: Choosing Endpoints and HTTP Methods

20 min
This lesson explains how to choose clear, resource-based API endpoints and match them with the right HTTP methods. You will learn how to design URLs that reflect business objects, when to use GET, POS…

Lesson 9: Query Parameters, Filtering, and Pagination

19 min
Query parameters are one of the simplest ways to make an API more useful without changing the endpoint itself. They let clients filter results, sort data, choose fields, and control page size while ke…

Reliability
