Connecting to SharePoint using Azure App Authentication and Python: A Step-by-Step Guide
Connecting to SharePoint via Azure app authentication can often be a daunting task, especially if you're new to Python. If you've tried creating a self-signed certificate and uploading it to an Azure app registration but are facing issues with your script, you're not alone! In this guide, we’ll explore the problem you might be encountering and then provide a straightforward solution for successfully connecting your Python application to SharePoint.
The Problem: Error in Connecting to SharePoint
While attempting to connect to your SharePoint site using Python's office365 library, you may encounter errors related to your certificate. Your error message might look something like this:

This error suggests that there might be an issue with the format or type of the certificate you are using. Let's walk through the solution to this common problem.
Solution: Generating the Certificate Correctly
Step 1: Understanding the Certificate Format
The first step in resolving this issue is ensuring that you have the certificate in the correct format. You initially used PowerShell to generate your certificate, exporting it in both .pfx and .pem formats. However, you found that your Python script does not accept these certificates.
PEM Format: For the office365 library to recognize your certificate, it must be in PEM format. This format generally begins with a line like -----BEGIN CERTIFICATE-----.
Step 2: Using Azure Key Vault for Certificate Creation
After struggling with the PowerShell-generated certificates, you found a more reliable method: creating the certificate using Azure Key Vault. Azure Key Vault provides a streamlined experience for managing certificates which are more readily accepted by other Azure services.
Here’s how you can generate a certificate in Azure Key Vault and download it in the correct format:
Create a Key Vault where you'll store your certificate.
Generate a Self-Signed Certificate directly in Key Vault.
Download the Certificate in PEM Format using the Azure Portal or Azure CLI, ensuring it follows the correct structure.
Example Code to Connect using Python
Here's how your Python script will look when configured correctly:

Step 3: Testing the Connection
Once you've updated your Python script with the new certificate:
Run your script.
If everything is set up correctly, you should be able to retrieve the SharePoint URL without encountering the previous error.
Conclusion
Connecting to SharePoint using Azure app authentication in Python does not have to be complicated! By using Azure Key Vault to create and manage your certificates, you can avoid the pitfalls associated with manual certificate generation. Ensure that your certificates are in the correct PEM format, and you'll be well on your way to successful integration with SharePoint.
