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

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.

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

Go to project selector

Verify that billing is enabled for your Google Cloud project .

Enable the Cloud Billing API.

Enable the API

Create a service account:

In the Google Cloud console, go to the Create service account page.
Go to Create service account
Select your project.
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 .
Click Create and continue .
Grant the Project > Owner role to the service account.

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

Note : The Role field affects which resources the service account can access in your project. You can revoke these roles or grant additional roles later. In production environments, do not grant the Owner, Editor, or Viewer roles. Instead, grant a predefined role or custom role that meets your needs.
Click Continue .
Click Done to finish creating the service account.

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

Create a service account key:

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

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.

Example:Linux or macOS

 export 
  
 GOOGLE_APPLICATION_CREDENTIALS 
 = 
 "  KEY_PATH 
 
"

Replace KEY_PATH with the path of the JSON file that contains your credentials.

For example:

 export 
  
 GOOGLE_APPLICATION_CREDENTIALS 
 = 
 "/home/user/Downloads/service-account-file.json"

Example:Windows

For PowerShell:

 $env 
:GOOGLE_APPLICATION_CREDENTIALS = 
 "  KEY_PATH 
 
"

Replace KEY_PATH with the path of the JSON file that contains your credentials.

For example:

 $env 
:GOOGLE_APPLICATION_CREDENTIALS = 
 "C:\Users\username\Downloads\service-account-file.json"

For command prompt:

 set 
  
 GOOGLE_APPLICATION_CREDENTIALS 
 = 
  KEY_PATH

Replace KEY_PATH with the path of the JSON file that contains your credentials.

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

In the Google Cloud console, go to the Manage resources page.
Go to Manage resources
In the project list, select the project that you want to delete, and then click Delete .
In the dialog, type the project ID, and then click Shut down to delete the project.
