HTTP Put Method in Visual Studio Code - 3/7 | Introduction to Web API with .NET Core

Learn how to use the PUT method in a Web API with C#!

In this video, we continue building our API step by step. After learning how to retrieve data with GET and add new data with POST, it’s now time to update existing data using the PUT method.

We’ll walk through how to:
Create a PUT endpoint that updates data in a list
Pass an ID (index) to specify which item to update
Validate input to handle invalid IDs and empty requests
Test everything thoroughly with the Postman extension in Visual Studio Code
We’ll also look at real examples of successful and failed requests, so you can understand how error handling works in practice. Finally, we’ll confirm that the update was successful by fetching the updated list.

What you’ll learn:
✅ How the PUT method works in Web API
✅ How to update existing data by ID
✅ How to handle errors and validation
✅ How to test PUT requests in Postman
