In this part of the course, you will learn the basics of creating APIs using FastAPI. We’ll start with HTTP basics and then move on to installing FastAPI and creating a simple “Hello World” API. We will also focus on OpenAPI for automatic documentation and the use of tags and routers in FastAPI, which will allow for better organization and management of your API.

You’ll start by learning how to use the various HTTP methods that are crucial to the operation of the API. We will then move on to using query and path parameters, which enable a more dynamic and flexible API. We will also focus on data validation and appropriate HTTP statuses, which is important for creating reliable and professional APIs. Finally, we’ll look at request body support, including JSON data and forms, which will allow you to effectively manage inputs in your API.

At this stage, you will learn to manage headers, cookies and CORS configuration, understand the dependencies in FastAPI, explore the basics of OAuth 2.0 and learn authentication and authorization methods. This will allow you to create safe and functional APIs.

You will focus on integration with databases and file management. You will learn to use SQLAlchemy, a popular Python ORM tool, to effectively manage databases. Then we will move on to performing background tasks, which is crucial for operations that require more time and should not block the main application thread. Finally, you will gain skills in uploading and downloading files, which will allow you to support a variety of data formats in your API.
