Webhooks with .NET 5-0daytown

What you’ll learn:
What Webhooks are and how to build them using C# and .NET 5
How to build REST APIs using C# and .NET 5
Use JavaScript (and “fetch”) to make API Calls
How to create multiple HttpClients using HttpClient Factory in .NET
What RabbitMQ is and how you can use it to enhance your solutions
How to run SQL Server and RabbitMQ Servers with Docker Compose
How to add Dependency Injection to a basic .NET Console app
Automapper and Data Transfer Objects

Requirements
Working understanding of C# & .NET
Exposure to building REST APIs with C# & .NET (students can take my free course on YouTube)

Description
In this hands-on, “no fluff / no filler” course we take a practical approach to building a working solution that uses Webhooks. We’ll cover some theory to start, but very quickly we jump into the practical step by step solution build which forms the vast majority of the course.

During the build, we will create 3 separate .NET Projects to simulate a fictional airline and its travel-agent customers. This approach will give students a real-world grounding in the use of webhooks and the value they bring to industry. The projects we build are:

Airline Web

Webhook Registration REST API

Flight Details REST API – used to trigger webhook by publishing to RabbitMQ message bus

Simple HTML / JavaScript / Bootstrap Web Client to make webhook registration API calls

Airline Send Agent

Stand alone “agent” used to send webhooks “en-mass”

Dependency Injection enabled

RabbitMQ Subscriber / Consumer with event based message delivery

Uses HttpClient and HttpClientFactory

Travel Agent Web

Simple Webhook POST Endpoint

Uses SQL Server backend to retrieve webhook “secret” to authenticate webhooks

We also use Docker Compose to set up and run following solution fabric:

RabbitMQ Server

Microsoft SQL Server

Students should be aware that we use VSCode as the development tool of choice, so students wanting to learn with Visual Studio should consider this carefully before purchasing.
