App Engine Admin API C++ Client Library

An idiomatic C++ client library for the App Engine Admin API, a service to Provisions and manages developers' App Engine applications.

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/appengine/quickstart/ directory, which should give you a taste of the App Engine Admin API C++ client library API.

#include "google/cloud/appengine/v1/services_client.h"
#include <iostream>

int main(int argc, char* argv[]) try {
  if (argc != 2) {
    std::cerr << "Usage: " << argv[0] << " app-id\n";
    return 1;

  namespace appengine = ::google::cloud::appengine_v1;
  auto client = appengine::ServicesClient(appengine::MakeServicesConnection());

  ::google::appengine::v1::ListServicesRequest request;
  request.set_parent(std::string{"apps/"} + argv[1]);
  for (auto r : client.ListServices(request)) {
    if (!r) throw std::move(r).status();
    std::cout << r->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.
