Cloud Billing API C++ Client Library

An idiomatic C++ client library for Cloud Billing API, a service that interacts with billing accounts, billing budgets, and billing catalogs.

While this library is GA, please note Google Cloud C++ client libraries do not follow Semantic Versioning.


The following shows the code that you'll run in the google/cloud/billing/quickstart/ directory, which should give you a taste of the Cloud Billing Budget API C++ client library API.

#include "google/cloud/billing/v1/cloud_billing_client.h"
#include <iostream>

int main(int argc, char* argv[]) try {
  if (argc != 1) {
    std::cerr << "Usage: " << argv[0] << "\n";
    return 1;

  namespace billing = ::google::cloud::billing_v1;
  auto client =

  for (auto a : client.ListBillingAccounts()) {
    if (!a) throw std::move(a).status();
    std::cout << a->DebugString() << "\n";

  return 0;
} catch (google::cloud::Status const& status) {
  std::cerr << "google::cloud::Status thrown: " << status << "\n";
  return 1;

Main classes

This library offers multiple *Client classes, which are listed below. Each one of these classes exposes all the RPCs for a service as member functions of the class. This library groups multiple services because they are part of the same product or are often used together. A typical example may be the administrative and data plane operations for a single product.

The library also has other classes that provide helpers, configuration parameters, and infrastructure to mock the *Client classes when testing your application.
