Learn to build modern backend services by creating real REST APIs with Python and FastAPI. This free online course guides you from the first concept of what an API is to the moment your application can persist data in a PostgreSQL database. Along the way, you will practice the essentials that backend developers use daily: designing endpoints, handling requests safely, validating input, returning clear responses, and testing everything with the right tools.
You start by setting up a productive development environment in Visual Studio Code and understanding what you need to run Python reliably. From there, you create a virtual environment so each project stays clean, repeatable, and easy to share. Once the FastAPI app is running, you see how a development server behaves, why hot reload speeds up iteration, and how routing works when multiple functions compete for the same path.
As you build your API, you will work with common HTTP methods and learn when to choose each one. You will create endpoints for reading, creating, updating, and deleting resources, while also learning the practical difference between GET and POST, and the purpose of PUT for updates. To make your API more professional, you will apply schema validation so your application can reject bad data early and consistently, reducing bugs and making behavior predictable for clients.
Testing becomes second nature as you use Postman to send requests and inspect responses. You will interpret HTTP response status codes to communicate outcomes clearly, including what it means when a response intentionally has no content. Finally, you will connect your API to PostgreSQL and manage the database using pgAdmin. With database operations and proper commits, your data survives server restarts and your API moves closer to production-ready behavior.
By the end, you will have the confidence to spin up a FastAPI project from scratch, structure endpoints sensibly, and connect persistent storage, giving you a strong foundation for backend development, portfolio projects, and further learning in Python web services.
