CreateBillingAccountRequest

JSON representation 
{
  "billingAccount": {
    object (BillingAccount)
  },
  "parent": string
}
Fields
billingAccount

object (BillingAccount)

Required. The billing account resource to create. Currently CreateBillingAccount only supports subaccount creation, so any created billing accounts must be under a provided parent billing account.
parent

string

Optional. The parent to create a billing account from. Format: - billingAccounts/{billing_account_id}, for example, billingAccounts/012345-567890-ABCDEF

BillingAccount

JSON representation 
{
  "name": string,
  "open": boolean,
  "displayName": string,
  "masterBillingAccount": string,
  "parent": string,
  "currencyCode": string
}
Fields
name

string

Output only. The resource name of the billing account. The resource name has the form billingAccounts/{billing_account_id}. For example, billingAccounts/012345-567890-ABCDEF would be the resource name for billing account 012345-567890-ABCDEF.
open

boolean

Output only. True if the billing account is open, and will therefore be charged for any usage on associated projects. False if the billing account is closed, and therefore projects associated with it are unable to use paid services.
displayName

string

The display name given to the billing account, such as My Billing Account. This name is displayed in the Google Cloud Console.
masterBillingAccount

string

If this account is a subaccount, then this will be the resource name of the parent billing account that it is being resold through. Otherwise this will be empty.
parent

string

Output only. The billing account's parent resource identifier. Use the MoveBillingAccount method to update the account's parent resource if it is a organization. Format: - organizations/{organization_id}, for example, organizations/12345678 - billingAccounts/{billing_account_id}, for example, billingAccounts/012345-567890-ABCDEF
currencyCode

string

Optional. The currency in which the billing account is billed and charged, represented as an ISO 4217 code such as USD.

Billing account currency is determined at the time of billing account creation and cannot be updated subsequently, so this field should not be set on update requests. In addition, a subaccount always matches the currency of its parent billing account, so this field should not be set on subaccount creation requests. Clients can read this field to determine the currency of an existing billing account.

Output Schema
