A smarter way to learn with interactive, real-time conversations that help you test your knowledge, challenge assumptions, and deepen your understanding as you progress through the course. This course is designed to help developers master the creation and protection of Web APIs using ASP.NET Core. You’ll gain hands-on experience with scaffolding, data validation, DTO implementation, and API security, building confidence to design scalable and secure backend systems. By combining theory with practical coding exercises, you’ll develop a strong foundation in API development best practices. The course begins with scaffolding database-driven API endpoints for countries and hotels, guiding you through controller generation, testing, and refactoring for optimal performance. You will then learn to implement DTOs for data shaping, validation, and security, improving your API’s reliability and structure while reducing potential vulnerabilities. Next, you’ll dive into implementing a service layer, exploring dependency injection, AutoMapper, and the Results Pattern to organize business logic and standardize responses. Advanced security topics follow, covering authentication mechanisms, JWT, API keys, roles, and authorization policies, ensuring your APIs are protected against common threats. You will also implement hotel booking functionality, integrating RESTful principles, user and admin booking management, advanced validation, and thorough testing. Finally, the course explores advanced architecture concepts, including project layout patterns, separate core, data, and application layers, and the Options Pattern, equipping you to build maintainable and scalable APIs. By the end of the course, you will be able to scaffold and secure database-driven API endpoints, implement DTOs for data validation and shaping, design a robust service layer with dependency injection and AutoMapper, apply multiple authentication schemes and authorization policies, and structure a scalable API architecture following best practices in ASP.NET Core.

In this module, we will introduce scaffolding in ASP.NET Core and demonstrate how it accelerates API development. You will scaffold controllers for countries data, review the generated code, and refine it for efficiency. The module concludes with hands-on testing to ensure your endpoints work flawlessly.

Häufig gestellte Fragen

Building and securing web APIs with ASP.NET Core involves creating application programming interfaces that allow different software systems to communicate securely and efficiently. It is relevant because modern web and mobile applications rely heavily on APIs, and ensuring these APIs are both functional and secure is essential for protecting user data and enabling reliable services.

This course guides learners through developing API endpoints using ASP.NET Core, covering database-driven scaffolding, implementing DTOs for data shaping and validation, creating a service layer, and applying robust security measures including authentication and authorization. It also covers practical features like hotel booking management and advanced architectural patterns to ensure scalable, maintainable APIs.

After completing this course, you will be able to scaffold and implement API endpoints, enforce data validation and shaping with DTOs, separate business logic using a service layer, secure APIs with multiple authentication schemes including JWT and API keys, manage user roles and permissions, and design scalable API architectures suitable for real-world applications.

You will learn to implement multiple authentication mechanisms including Basic Authentication, API Key Authentication, and JWT-based authentication, as well as role-based authorization to control access to different API endpoints. These security techniques ensure that your APIs are protected against unauthorized access and data breaches.
