More info on BillingEntitlement

Hello,

I need to know what is BillingEntitelement as per document link https://cloud.google.com/channel/docs/reference/rest/v1alpha1/accounts.customers.billingEntitlements

How do we get EntitlementID {id} so that we can use it in API parameter.

Basically i am creating a dashboard using Google Data Studio with the source as Cloud Billing data from Bigquery,Refer link https://cloud.google.com/billing/docs/how-to/export-data-bigquery.

Now the cloud billing data does not have a company name but rather it has information about , Billing Account Id, Service type, cost etc,

My agenda is to create a table with Data Studio with column CompanyDomainName | Company Name | Total Cost , Is there are better way to extract CompanyName or OrgName based on the information available from Cloud billing Data
