    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 Cloud account. If you're new to Google Cloud, create an account to evaluate how our products perform in real-world scenarios. New customers also get $300 in free credits to run, test, and deploy workloads.

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

      Roles required to select or create a project

      • Select a project : Selecting a project doesn't require a specific IAM role—you can select any project that you've been granted a role on.
      • Create a project : To create a project, you need the Project Creator role ( roles/resourcemanager.projectCreator ), which contains the resourcemanager.projects.create permission. Learn how to grant roles .

      Go to project selector

    3. Verify that billing is enabled for your Google Cloud project .

    4. Enable the Cloud Billing API.

      Roles required to enable APIs

      To enable APIs, you need the Service Usage Admin IAM role ( roles/serviceusage.serviceUsageAdmin ), which contains the serviceusage.services.enable permission. Learn how to grant roles .

      Enable the API

    5. Create a service account:

      1. Ensure that you have the Create Service Accounts IAM role ( roles/iam.serviceAccountCreator ) and the Project IAM Admin role ( roles/resourcemanager.projectIamAdmin ). Learn how to grant roles .

      2. In the Google Cloud console, go to the Create service account page.

        Go to Create service account
      3. Select your project.

      4. In the Service account name field, enter a name. The Google Cloud console fills in the Service account ID field based on this name.

        In the Service account description field, enter a description. For example, Service account for quickstart .

      5. Click Create and continue .

      6. Grant the Project > Owner role to the service account.

        To grant the role, find the Select a role list, then select Project > Owner .

      7. Click Continue .

      8. Click Done to finish creating the service account.

        Do not close your browser window. You will use it in the next step.

    6. Create a service account key:

      1. In the Google Cloud console, click the email address for the service account that you created.
      2. Click Keys .
      3. Click Add key , and then click Create new key .
      4. Click Create . A JSON key file is downloaded to your computer.
      5. Click Close .

    7. Set the environment variable GOOGLE_APPLICATION_CREDENTIALS to the path of the JSON file that contains your credentials. This variable applies only to your current shell session, so if you open a new session, set the variable again.

    8. In the Google Cloud console, on the project selector page, select or create a Google Cloud project.

      Roles required to select or create a project

    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 Google 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.
