Add an additional Administrator to APIM instance

Question

I have my APIM instance that is connected to AAD. How can I add a second administrator to the instance? Users signing in through the Developer Portal show up with the Developer role. But how do I add a second administrator?

Answer 1

You cannot add second administrator to the APIM service as mentioned in this document

Administrators groups is an immutable system group. Azure subscription administrators are members of this group. You cannot add a user to this group.
