REST APIs with Flask and Python in 2025

Build professional REST APIs with Python, Flask, Docker, Flask-Smorest, and Flask-SQLAlchemy

Are you tired of boring, outdated, incomplete, or incorrect tutorials? I say no more to copy-pasting code that you don’t understand.

Welcome to the bestselling REST API course on Udemy! I'm Jose. I'm a software engineer, here to help you truly understand and develop your skills in web and REST API development with Python, Flask, and Docker.

Production-ready REST APIs with Flask

This course will guide you in creating simple, intermediate, and advanced REST APIs including authentication, deployments, databases, and much more.

We'll start with a Python refresher that will take you from the very basics to some of the most advanced features of Python—that's all the Python you need to complete the course.

Using Flask and popular extensions Flask-Smorest, Flask-JWT-Extended, and Flask-SQLAlchemy we will dive right into developing complete, solid, production-ready REST APIs.

We will also look into essential technologies like Git and database migrations with Alembic.

You'll be able to...

• Create resource-based, production-ready REST APIs using Python, Flask, and popular Flask extensions;

• Handle secure user registration and authentication with Flask.

• Using SQLAlchemy and Flask-SQLAlchemy to easily and efficiently store resources to a database; and

• Understand the complex intricacies of deployments of Flask REST APIs.

• Use Docker to simplify running and deploying your REST APIs.

But what is a REST API anyway?

A REST API is an application that accepts data from clients and returns data back. For example, a REST API could accept text data from the client, such as a username and password, and return whether that is a valid user in the database.

When developing REST APIs, our clients are usually web apps or mobile apps. That's in contrast to when we make websites, where the clients are usually the users themselves.

Together we'll develop a REST API that not only allows clients to authenticate but also to store and retrieve any data you want from a database. Learning this will help you develop any REST API that you need for your own projects!

I pride myself on providing excellent support and feedback to every single student. I am always available to guide you and answer your questions.

I'll see you on the inside. Take your first step towards REST API mastery!
