Fetch billing properties of Azure b2c tenant from API

Question

I have been working on b2c from a couple of weeks. I created many resources like applications, users, user flows, policies.

I want to know the billing details of this particular tenant.

I found this query where I can get charges list within a scope:

GET https://management.azure.com/{scope}/providers/Microsoft.Consumption/charges?api-version=2021-10-01

Any way to filter this query so that it shows details only related to b2c tenant

But I'm not sure whether this is correct or not. Can anyone with this domain knowledge help me out whether I'm on right path or any modifications needed?

Answer 1

To get billing properties of your B2C tenant, you need to use query like below:

GET https://management.azure.com/subscriptions/{subscriptionId}/resourceGroups/{resourceGroupName}/providers/Microsoft.AzureActiveDirectory/b2cDirectories/{resourceName}?api-version=2019-01-01-preview

I tried to reproduce the same in my environment and got below results:

I registered one Azure AD application and added API permissions as below:

Make sure to enable tokens if you are using implicit flow to acquire access token like below:

To get the access token, I made Authorization request in browser like below:

https://login.microsoftonline.com/<tenant_ID>/oauth2/v2.0/authorize?
client_id=74b2a1ba-xxxx-4xxc-axx1-c2xxxxxxxx
&response_type=token
&redirect_uri=https://jwt.ms
&scope=https://management.azure.com/user_impersonation
&response_mode=fragment
&state=12345
&nonce=678910

When I ran the above request, I got the token in the address bar as below:

I executed the query via Postman and got the billing properties of my B2C tenant successfully like below:

GET https://management.azure.com/subscriptions/{subscriptionId}/resourceGroups/{resourceGroupName}/providers/Microsoft.AzureActiveDirectory/b2cDirectories/{b2ctenantdomain}?api-version=2019-01-01-preview

UPDATE

To get the details like the resource group in which B2C tenant is created, you can run below PowerShell command:
