Where can I find Service Principal GUID from Azure Portal

Question

I need to create a service principal and assign a new role to it through Python SDK. I am currently following steps as listed from this stackoverflow question .

I am currently working on the role assignment and I am stuck on the step of I need to input a principal_id . For example, as needed here to create a new role assignment. Where can I find this service principal id in Azure portal? Is it the appId or objectId under Azure Portal-> Active Directory -> App Registration -> My app?

Answer 1

What I am confused about is which Id for my app is corresponding to the principal_id it's asking here. Is it the appId or the objectId for my app?

None of these. There should be a service principal tied to the application. That will have an ID.

PS. The screenshot is of the App Registration blade in the Azure portal.
