Send Requests

This topic shows how to send a few simple requests to the Cloud Billing API.

For a full list of methods, see the REST or RPC reference documentation.

Before you begin

  1. Sign in to your Google Account.

    If you don't already have one, sign up for a new account.

  2. In the Google Cloud Console, on the project selector page, select or create a Google Cloud project.

    Go to the project selector page

  3. Make sure that billing is enabled for your Cloud project. Learn how to confirm that billing is enabled for your project.

  4. Enable the Cloud Billing API.

    Enable the API

  5. Set up authentication:
    1. In the Cloud Console, go to the Create service account key page.

      Go to the Create Service Account Key page
    2. From the Service account list, select New service account.
    3. In the Service account name field, enter a name.
    4. From the Role list, select Project > Owner.

    5. Click Create. A JSON file that contains your key downloads to your computer.
  6. Set the environment variable GOOGLE_APPLICATION_CREDENTIALS to the path of the JSON file that contains your service account key. This variable only applies to your current shell session, so if you open a new session, set the variable again.

Get a list of Cloud Billing Accounts

The API method to list all Cloud Billing Accounts (REST, RPC) is the simpest method in the API, as it has no required parameters, so it's a good place to start. The method simply returns all billing accounts that you have permission to view.




    ListBillingAccountsResponse result = service.billingAccounts().list().execute();

Retrieve a particular Cloud Billing Account

To retrieve a particular billing account (REST, RPC), you'll need to know the billing account ID. This example uses the sample ID 012345-567890-ABCDEF.




    BillingAccount result = service.billingAccounts()

Enable Cloud Billing on a Google Cloud project

To enable Cloud Billing on a Cloud project, you need to call the Cloud Billing API to associate the Cloud project with an existing Cloud Billing Account (REST, RPC). The following sample code associates Cloud project tokyo-rain-123 with Cloud Billing Account 012345-567890-ABCDEF. Incidentally, the same API method can be used to disable Cloud Billing on a Cloud project, by setting billingAccountName to empty.



  "billingAccountName": "billingAccounts/012345-567890-ABCDEF"


            new ProjectBillingInfo().setBillingAccountName("billingAccounts/012345-567890-ABCDEF"))

Clean up

  1. In the Cloud Console, go to the Manage resources page.

    Go to Manage resources

  2. In the project list, select the project that you want to delete, and then click Delete.
  3. In the dialog, type the project ID, and then click Shut down to delete the project.
