Have you ever implemented Google Maps in your application or have seen an app that makes use of Google Maps? With REST we always try to adhere to the HTTP protocol as much as we can. Now that we need to implement authentication we should do so in the context of HTTP, which provides two forms of authentication called Basic and Digest. In my opinion this is a serious problem that should always be addressed. Well, we are done with the functionality of our service, but we still have a problem. The problem with the current design of the API is that clients are forced to construct URIs from the task identifiers that are returned.
Providing a descriptive error message gives the user more context for the error. This POST request includes JSON for the new car in the request. It sets the Content-Type header to application/json so the API knows the content type of the request. The first step you’ll take as you build a REST API is to identify the resources the API will manage. It’s common to describe these resources as plural nouns, like customers, events, or transactions.
Building RESTful APIs with Flask: A Step-by-Step Tutorial
An API is just a medium that lets two entities of code talk to each other. Of course if we do this we will need the client application to look for 403 errors as well. Before we delve into the specifics of web services let’s review how a regular Flask web application is structured. If you read my Flask Mega-Tutorial series you know that Flask is a simple, yet very powerful Python web framework. In this article I’m going to show you how easy it is to create a RESTful web service using Python and the Flask microframework.
After that, we create a course, and we make a GET request that states if anyone hits on this class, then he will get Hello world as the response in JSON format. To switch on a particular URL, we use the add resource method and route it to the default slash. To run this file, you can use the POSTMAN tool, an API maintenance tool, to create, test, and manage APIs.

This application could be expanded to include endpoints for all the other HTTP methods. This code uses @app.get(), a Flask route decorator, to connect GET requests to a function in the application. When you access /countries, Flask calls the restful api python flask decorated function to handle the HTTP request and return a response. Once flask is installed, save the code in a file called app.py. To run this Flask application, you first need to set an environment variable called FLASK_APP to app.py.
In the world of web development, creating robust RESTful APIs is an essential skill. REST (Representational State Transfer) is a widely used architectural style for designing networked applications. Flask, a micro web framework for Python, provides an excellent platform for building RESTful APIs due to its simplicity and flexibility.
REST and Python: Tools of the Trade
This response has a 201 Created status code to tell the user that a new resource was created. Make sure to use 201 Created instead of 200 OK for all successful POST requests. This response contains a single JSON object with the car’s data. Since it’s a single object, it doesn’t need to be wrapped in a list. Once you’ve picked a data format, the next step is to decide how you’ll respond to HTTP requests.
