This blog post explains how to configure access for my Service Principal to interact with the Azure Storage API to use the API to get details for Microsoft Fabric Storage.

This is part of a blog post series where I am going to show you how to “View Total Storage consumed in Microsoft Fabric”

When I started this blog post I realized that I first need to explain how to configure the Service Principal authentication to interact with the Azure Storage API permissions. This is because in my notebook these steps are required for the notebook to run successfully.

NOTE: In my example I am using my Fabric Service Principal which is also used for the Power BI and Fabric Admin API requests. Because the Azure Storage permission is not related to the Power BI or Fabric APIs this API can be used.

NOTE II: The Fabric Service Principal already has got all the required permissions for Power BI and Fabric APIs requests, so using an existing Service Principal makes sense as one less thing to manage and configure.

Setting up Service Principal and permissions

Below is how to set up the Service Principal and permissions for the Azure Storage

Once the Service Principal has been created, it then needs the following API Permissions
