        # the new billing account by setting the `billing_account_name` in the
        # `ProjectBillingInfo` resource to the resource name of a billing account.
        # Associating a project with an open billing account enables billing on the
        # project and allows charges for resource usage. If the project already had a
        # billing account, this method changes the billing account used for resource
        # usage charges.
        # *Note:* Incurred charges that have not yet been reported in the transaction
        # history of the Google Cloud Console may be billed to the new billing
        # account, even if the charge occurred before the new billing account was
        # assigned to the project.
        # The current authenticated user must have ownership privileges for both the
        # [project](https://cloud.google.com/docs/permissions-overview#h.bgs0oxofvnoo
        # ) and the [billing
        # account](https://support.google.com/cloud/answer/4430947).
        # You can disable billing on the project by setting the
        # `billing_account_name` field to empty. This action disassociates the
        # current billing account from the project. Any billable activity of your
        # in-use services will stop, and your application could stop functioning as
        # expected. Any unbilled charges to date will be billed to the previously
        # associated account. The current authenticated user must be either an owner
        # of the project or an owner of the billing account for the project.
        # Note that associating a project with a *closed* billing account will have
        # much the same effect as disabling billing on the project: any paid
        # resources used by the project will be shut down. Thus, unless you wish to
        # disable billing, you should always call this method with the name of an
        # *open* billing account.
