HTTP POST and PUT in ASP.NET Core APIs

When building modern web applications, handling data submissions and updates reliably is a core requirement. This written course guides you through the essential mechanics of HTTP POST and PUT requests within ASP.NET Core Web APIs, ensuring your backend handles data mutations safely and efficiently. You will start with the fundamental concepts of HTTP methods, learn how they map to CRUD operations, and explore how ASP.NET Core processes incoming payloads. By reading through clear explanations and structured code examples, you will gain a deep understanding of resource creation, complete resource updates, and modern API design patterns. You will learn to write clean, asynchronous controller actions and integrate them with databases using Entity Framework Core, while also exploring contemporary API standards like model validation, proper HTTP status codes, and type-safe data transfer objects. What you'll learn: - Understand the core differences, idempotency rules, and use cases for HTTP POST and PUT methods - Configure asynchronous database operations within ASP.NET Core using Entity Framework Core - Implement robust input validation using modern model binding and data annotations - Map incoming JSON payloads to database entities safely using Data Transfer Objects (DTOs) - Return correct HTTP status codes and response headers to maintain standard-compliant API communication - Handle concurrent updates and basic database exception scenarios during API mutations This course begins with foundational HTTP concepts and API architecture before moving into step-by-step implementation patterns for data creation and modification. You will read through realistic scenarios, analyze code structures, and learn to debug common API binding issues. This course is designed for beginner backend developers, web development students, and software engineers who are familiar with C# basics and want to build reliable RESTful services. No advanced API experience is required to begin. Start reading today to master data handling in ASP.NET Core.
