That was a challenge that was accepted. I´ve spent some time learning from Microsoft documentation how to extract data from Azure (https://docs.microsoft.com/en-us/rest/api/billing/) and after some time was possible to connect Qlik Sense to the API and extract data using our REST connector.
This app is 100% pure Qlik Sense script, you have everything you need in your SaaS Tenant or Client Managed instance. No special drivers or connectors are required.
Please feel free to contribute and suggest any improvements
