How to Perform a POST Request in Python with Basic Authentication and Token

When working with web APIs, making requests is a common task for developers. However, you might encounter issues when trying to implement a POST request in Python, especially when basic authentication and tokens are involved.

In this guide, we’ll explore how to successfully execute a POST request with the necessary authentication in Python using the Requests library. If you’ve ever run into a 403 Forbidden error, you’re not alone. Let's break down the process step-by-step.

Understanding the Problem

You may have tested your POST request in tools like Postman without any issues, but when you try to implement it in Python, you receive a status code of 403. This usually indicates that the request is not authorized for some reason. In your case, the goal is to make a POST request that requires:

Basic authentication

A CSRF token retrieved from a previous GET request

Here are the key steps you need to follow:

Authenticate using basic authentication

Fetch a CSRF token using a GET request

Use this token in the header for your POST request

Solution: Step-by-Step Guide

To perform these actions correctly, you need to utilize the requests.Session() object. This allows you to persist certain parameters across requests, making your API calls more efficient.

Step 1: Import the Necessary Modules

First, ensure you import the necessary modules from the Requests library:

Step 2: Create a Session Object

Start by creating a session. This session will be used to both fetch your token and send your POST request.

Step 3: Fetch the CSRF Token

You’ll need to make a GET request to retrieve the CSRF token. Pass in your authentication credentials and any required headers.

Step 4: Execute the POST Request

Now that you have the token, you can make the POST request with the required authentication and headers. Ensure to send your data in a compatible format (like JSON).

Conclusion

By following these steps, you should successfully perform a POST request in Python with basic authentication and a CSRF token. Always ensure that you’re using a session when dealing with requests requiring multiple interactions, as it simplifies managing your connections and authentication.

Now you should be able to confidently implement POST requests in your Python applications without encountering a 403 Forbidden status code again! Happy coding!
