Advanced REST APIs with Flask and Python

Video description

This Advanced REST API course takes your REST API development to a whole new level by familiarizing you with more of the Flask ecosystem. We start with a simple REST API and teach you everything you need to know about it. We introduce new features and technologies by baking them into this application so you can see how a professional REST API is developed. Every new feature is added to a fully working application and tested. We also help you understand more about how to build features incrementally so you can get them to your users quickly and minimize risk.

Remember, this is our most advanced course yet! You should have adequate programming experience with Python or another programming language. Some knowledge of how the web works will also be helpful.

You should have prior knowledge of how to install Python packages and how to run your Python applications. If you've used virtualenv or Pipenv before, that's excellent! Knowledge of how to use PyCharm for debugging is also a plus, although we cover using the debugger in the course!

What You Will Learn

  • Use Marshmallow for data serialization and deserialization
  • Send e-mails and user confirmations
  • Upload images, Database migrations
  • Easy ways to write documentation and test your API
  • Handle payments using Stripe
  • Third-party login using OAuth
  • Master software development, refactoring, debugging, and more!
  • Use the latest technologies and best practices.

Audience

This course is designed for software developers who want to add advanced functionality to REST APIs, backend developers interested in gaining knowledge of Flask and its ecosystem, and advanced developers of other programming languages who want to get up-to-speed quickly with advanced REST API development in Python
