Learn Webhooks by Building a Notification Service (Python + FastAPI + Docker)
In this video, I’ll walk you through building a simple webhook notification service using Python, FastAPI, and Docker Compose.
Github: https://github.com/khalludi/notif_web...
We’ll design two microservices:
Notifier UI Service: a FastAPI backend with a lightweight database and a minimal React UI to send and track messages.
Provider Service: a simulated third-party provider that waits a few seconds before sending a webhook callback (success or error).
Along the way, I’ll cover:
✅ What webhooks are and why they matter
✅ High-level architecture & design decisions
✅ Setting up Python microservices with FastAPI
✅ Using Docker Compose to orchestrate multiple containers (services + DB)
✅ Live demo of sending messages and watching delivery statuses update
Whether you’re just learning webhooks or want to practice microservice design with Python, this hands-on project is a perfect starting point.
