I have had a lot of clients lately intergrade Azure with a third-party solution, like Cloud Checker, or Prisma Cloud, etc. These services are great but they require the configuration of an Azure Active Directory Enterprise app to setup permissions. I have had a couple of issues lately where a product (none of the above) struggle to connect and I open a support ticket with the solution provider. Their first questions are around the configuration of the app. After the second time I wrote this quick PowerShell script to login as the app and list the subscriptions. $url can be changed to whatever API call you need to check.
