REST APIs
Build, configure, and master REST APIs
Over two days, gain practical experience building RESTful services and clients with the latest tools and techniques. This course gives you immediate, job-ready skills to support development across web apps and microservices.
Learning objectives
- Understand key REST principles
- Build REST services using Java, Python or JavaScript
- Create REST clients with modern libraries
- Apply caching, compression and security
- Use the Richardson Maturity Model
- Resolve the n+1 problem
- Implement authentication techniques
- Work with HATEOAS and versioning
What you’ll learn
Learn how to design, build, and manage REST APIs, focusing on real-world development. Configure a REST API in terms of caching, compression and idempotence. Focus on defining and describing the Richardson Maturity Model, options for searching and sorting, and authentication techniques. Choose your language and leave with practical, job-focused skills.
Prerequisites and foundations
Using the skills you’ve already developed in either Java, Python or JavaScript, explore fundamental concepts such as APIs, web services, HTTP, JSON, and serialisation to establish the essential groundwork for working with REST APIs.
Core REST theory
Understand REST’s guiding principles, naming conventions, resource structure, and supported HTTP methods. Learn what makes an API truly RESTful.
Building REST services
Create REST services using Spring Boot (Java), Flask (Python), or Express (JavaScript) to support real-world applications and workflows.
Building REST clients
Develop clients using HttpClient (Java), Requests (Python), or Axios (JavaScript). Get familiar with off-the-shelf tools like Postman for testing and validation.
REST API configuration
Implement API features such as caching, compression, statelessness, and content negotiation. Learn documentation, versioning, and idempotence best practices.
Advanced topics and security
Apply the Richardson Maturity Model, solve the n+1 problem, and use modern authentication techniques. Understand how to improve performance and scalability.

FAQs
Our REST API course gives you practical experience designing, building, and configuring RESTful services and clients. Learn with the language of your choice and apply skills immediately.
What is a REST API and how does it work?
A REST API (Representational State Transfer) is a way for systems to communicate over HTTP using a uniform and stateless approach. It allows data to be requested and updated via clearly defined endpoints.
Will I work on real projects?
The course is packed with practical exercises that replicate real-world REST API scenarios (in a coding language you choose from Java, Python or JavaScript) to build your confidence and capability.
Do I need to install specific software before the course?
We’ll provide full joining instructions before your course starts, including any required software installation or configuration.
Can I ask questions during the training?
Yes. The sessions are interactive and led by an expert instructor, so you’re encouraged to ask questions and explore specific topics as they arise.
