Class CloudBillingClient (2.1.12)

Service Description: Retrieves GCP Console billing accounts and associates them with projects.

This class provides the ability to make remote calls to the backing service through method calls that map to API methods. Sample code to get started:

 try (CloudBillingClient cloudBillingClient = CloudBillingClient.create()) {
   BillingAccountName name = BillingAccountName.of("[BILLING_ACCOUNT]");
   BillingAccount response = cloudBillingClient.getBillingAccount(name);
 }
 

Note: close() needs to be called on the CloudBillingClient object to clean up resources such as threads. In the example above, try-with-resources is used, which automatically calls close().

The surface of this class includes several types of Java methods for each of the API's methods:

1. A "flattened" method. With this type of method, the fields of the request type have been converted into function parameters. It may be the case that not all fields are available as parameters, and not every API method will have a flattened method entry point.
2. A "request object" method. This type of method only takes one parameter, a request object, which must be constructed before the call. Not every API method will have a request object method.
3. A "callable" method. This type of method takes no parameters and returns an immutable API callable object, which can be used to initiate calls to the service.

See the individual methods for example code.

Many parameters require resource names to be formatted in a particular way. To assist with these names, this class includes a format method for each type of name, and additionally a parse method to extract the individual identifiers contained within names that are returned.

This class can be customized by passing in a custom instance of CloudBillingSettings to create(). For example:

To customize credentials:

 CloudBillingSettings cloudBillingSettings =
     CloudBillingSettings.newBuilder()
         .setCredentialsProvider(FixedCredentialsProvider.create(myCredentials))
         .build();
 CloudBillingClient cloudBillingClient = CloudBillingClient.create(cloudBillingSettings);
 

To customize the endpoint:

 CloudBillingSettings cloudBillingSettings =
     CloudBillingSettings.newBuilder().setEndpoint(myEndpoint).build();
 CloudBillingClient cloudBillingClient = CloudBillingClient.create(cloudBillingSettings);
 

Please refer to the GitHub repository's samples for more quickstart code snippets.

Constructs an instance of CloudBillingClient with default settings.

Constructs an instance of CloudBillingClient, using the given settings. The channels are created based on the settings passed in, or defaults for any settings that are not set.

Constructs an instance of CloudBillingClient, using the given stub for making calls. This is for advanced usage - prefer using create(CloudBillingSettings).

Constructs an instance of CloudBillingClient, using the given settings. This is protected so that it is easy to make a subclass, but otherwise, the static factory methods should be preferred.

Creates a billing account. This method can only be used to create billing subaccounts by GCP resellers. When creating a subaccount, the current authenticated user must have the billing.accounts.update IAM permission on the master account, which is typically given to billing account administrators. This method will return an error if the master account has not been provisioned as a reseller account.

Sample code:

 try (CloudBillingClient cloudBillingClient = CloudBillingClient.create()) {
   BillingAccount billingAccount = BillingAccount.newBuilder().build();
   BillingAccount response = cloudBillingClient.createBillingAccount(billingAccount);
 }

Sets or updates the billing account associated with a project. You specify 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 GCP Console might 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 and the billing account.

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.

Sample code:

 try (CloudBillingClient cloudBillingClient = CloudBillingClient.create()) {
   UpdateProjectBillingInfoRequest request =
       UpdateProjectBillingInfoRequest.newBuilder()
