Send Requests

This topic shows how to send a few simple requests to the Google 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 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 Google Cloud project. Learn how to confirm 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.

      Note: The Role field authorizes your service account to access resources. You can view and change this field later by using the Cloud Console. If you are developing a production app, specify more granular permissions than Project > Owner. For more information, see granting roles to service accounts.
    5. Click Create. A JSON file that contains your key downloads to your computer.
  6. Set the environment variable GOOGLE_APPLICATION_CREDENTIALS to the file 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.

Protocol

GET https://cloudbilling.googleapis.com/v1/billingAccounts

Java

    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.

Protocol

GET https://cloudbilling.googleapis.com/v1/billingAccounts/012345-567890-ABCDEF

Java

    BillingAccount result = service.billingAccounts()
        .get("billingAccounts/00C5EA-61187E-D842F2").execute();

Enable Cloud Billing on a Google Cloud project

To enable Cloud Billing on a Google Cloud project, you need to call the Cloud Billing API to associate the Google Cloud project with an existing Cloud Billing Account (REST, RPC). The following sample code associates Google 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 Google Cloud project, by setting billingAccountName to empty.

Protocol

PUT https://cloudbilling.googleapis.com/v1/projects/tokyo-rain-123/billingInfo

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

Java

    service.projects().updateBillingInfo(
            "projects/tokyo-rain-123",
            new ProjectBillingInfo().setBillingAccountName("billingAccounts/012345-567890-ABCDEF"))
        .execute();

Clean up

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

    Go to the Manage resources page

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