@RSdev You are pulling the billing summary data for the top level account. You would need to pull the relevant data from the child accounts you are targeting. For example if you wanted to find how many devices account XYZ had, you'd want to do a GET on {ACCOUNT_ID}/devices. ref: https://docs.2600hz.com/supported/applications/crossbar/doc/devices/#fetch. If you have any more questions, please put in a support ticket via your client and we can help you there
