Python API Tutorials

It is one of the oldest and the most popular web frameworks, with nearly 50k stars on GitHub. For more information, head over to the Hug GitHub repository, or explore the documentation. This is how you define a REST API resource using the Falcon’s object-oriented approach. Comments must be respectful, constructive, and relevant to the topic of the guide. Before posting, consider if your comment would be better addressed by contacting ourSupport team or asking on ourCommunity Site.

It uses a class for each resource and connects routes to instances of a resource. Due to the use of a class, it makes more sense to declare the hard-coded array of companies within the company resource class.

Bootstrapping a Flask Application

And be patient, we will talk about that in the subsequent chapters. For now, let’s stay simple and get ourselves familiar with Flask first. The Flask package that we are installing is a web micro-framework. python api design It is extremely lightweight and allows us to build a web service with just a few lines of code. PyCharm is going to prompt us on the missing package, as shown in the screenshot.

✅ DO increment the minor version if any new functionality is added to the package. There are occasions when common code needs to be shared between several client libraries. For example, a set of cooperating client libraries may wish to share a set of exceptions or models. ☑️ YOU SHOULD ship a separate package for async support if the async version requires additional dependencies. ✅ DO include any service-specific error information in the exception. Service-specific error information must be available in service-specific properties or fields. For higher-level methods that use multiple HTTP requests, either the last exception or an aggregate exception of all failures should be produced.

The second endpoint retrieves the details of a specific resource based on a unique identifier. In this section, you create two endpoints to GET resources from your API. This section may refer to these endpoints as the list and details endpoints.

We created a memory database of tasks, which is nothing more than a plain and simple array of dictionaries. Each entry in the array has the fields that we defined above for our tasks. There are a couple of Flask extensions that help with building RESTful services with Flask, but the task is so simple that in my opinion there is no need to use an extension. After creating the API, you will learn how to deploy the API using two different methods.

Summary: Top Python REST API Frameworks

Then we will look at real-life examples of how different web services use the REST API. We are in the internet era, a world where everything is connected. We can get all the information in the world with a few clicks on a website. See what organizations are doing to incorporate it today and going forward. The tool supports an intuitive editor and VSCode/PyCharm with autocompletion. It comes with an integrated security and authentication and dependency injection system to handle all the dependencies automatically.

You can choose to perform more tests by yourself if you want to. They just need to send an order through the waiter/waitress, and they will get the meal they ordered. This chapter introduces API and explains the concepts of web services, API and REST. Learn to design, build, and interact with APIs using Python.

Python API Design

Throughout this book, you will be our API engineering intern. We will guide you, step by step, through the process of developing a RESTful API project that can serve the users of your system.

• Combined scenarios require knowledge of additional operations that might be outside their current focus.
• For instance, if the goal is to develop a web application, then the framework provides libraries that ease the effort in coding the web frontend or the backend or both.
• That is, in the future, we will also install Docker and run our program on environments like production and staging.
• Designing the Artsy APIhas their recommendations list for building an API based on their experiences.
• It is usually hidden from users, so you probably didn’t realize it exists.
• Including the application name in the URL is useful to provide a namespace that separates this service from others that can be running on the same system.
