Added on October 14, 2025 IT & Software 2 min read

What you’ll learn

Explain the fundamental principles of APIs and how web services facilitate communication between modern applications.
Design and structure clean
efficient
and scalable RESTful APIs following industry best practices and conventions.
Build and deploy a functional RESTful API from scratch that can create
read
update
and delete data (CRUD).
Securely consume data from third-party APIs and integrate them effectively into your own web or mobile applications.

Requirements

“Learners should have a solid foundational understanding of at least one programming language
such as Python
JavaScript
or Java. Basic familiarity with the command line and data formats like JSON will be very helpful. No prior experience with building APIs or web services is necessary—thats what were here to learn!”

Description

Ever wondered how applications like Instagram, Uber, or Google Maps share data and work so seamlessly across your phone and the web? The magic behind it all is the powerful world of Web Services and APIs (Application Programming Interfaces), and this course is your friendly, comprehensive guide to mastering them.

APIs are the backbone of modern software development, acting as the invisible engine that allows different applications to communicate with each other. Understanding how to build and use them is one of the most crucial and in-demand skills for any developer today.

This course is designed to take you from an absolute beginner to a capable developer who can confidently design, build, and deploy robust RESTful APIs. We’ll demystify all the core concepts without the confusing jargon, focusing on practical, hands-on learning from the very first lesson.

Throughout this course, you will learn and master:

The Core Concepts: Understand exactly what Web Services are, how the HTTP protocol works, and why REST has become the industry standard for building APIs.
RESTful API Design: Learn the best practices for designing clean, predictable, and easy-to-use APIs, including proper endpoint structure, HTTP methods (GET, POST, PUT, DELETE), and status codes.
Hands-On Development: We’ll build a complete, real-world API from scratch. You’ll learn how to set up a server, define routes, connect to a database, and perform all essential CRUD (Create, Read, Update, Delete) operations.
Data Handling: Become proficient in working with JSON, the universal language of modern APIs, for sending and receiving data.
Security & Authentication: Grasp the fundamentals of securing your API endpoints to ensure that only authorized users can access your data.
Consuming Other APIs: It’s not just about building! You’ll also learn how to interact with popular third-party APIs to pull data into your own applications.

By the end of this course, you won’t just have a certificate; you’ll have a portfolio-ready project and the practical skills to build the back-end for your next big idea. If you’re a front-end developer looking to go full-stack, a student wanting to learn a high-value skill, or anyone curious about the back-end, this course is for you.
