I assume you have 2 service principal credentials in the publisher/ISV AAD tenant:
We need a management credential which is authorized to manage customer deployments, using with the ARM API.
I created an AAD group, called managed-app-admins, and made the service principal a member of that group.
In Partner Center -> Offer -> Plan -> Technical Configuration -> Authorizations, I granted the AAD group Owner of managed apps.
As a result, the isv_management_cliend_id below can interact with managed apps.
So 8cdea44d-38fe-4e3c-bf2a-6b96809d1d27 above is the object ID of the group, and the service principal with app id 8eff18b7-aeeb-4a88-b19c-bf60813a587c is member of that group.
We need a metering credential, which is authorized to submit usage to the metering API.
We do not use an identity in the managed app, i.e. we do not SSH/RDP into a VM in the managed resource group to do our work there. Having a VM just for that is too complicated (and expensive).
This isv_metering_client_id (app id) service principal is configured under Partner Center -> Offer -> Technical Configuration:
The script

# We now need to determine the resourceUri of the of the managed app (in the customer subscription). When submitting to the metering API, your JSON body must either contain
# a resourceUri, or a resourceId, or both. In case of a managed app, resourceUri is the way to go.

# The resourceUri we want to determine is the `managedBy` property of the managed resource group. In this sample, we go the long way, i.e. talk to ARM
# on customer side. We query the **managed resource group**, using our management credential.
#
# The value we want to retrieve looks like this:
