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 downloading.

Who this course is for:

Students interested in learning more about what webhooks are, why you'd use them and how to start building them.
