Cloud Tasks API C++ Client Library

An idiomatic C++ client library for Cloud Tasks API, a service that manages the execution of large numbers of distributed requests.

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


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

#include "google/cloud/tasks/v2/cloud_tasks_client.h"
#include "google/cloud/location.h"
#include <iostream>

int main(int argc, char* argv[]) try {
  if (argc != 3) {
    std::cerr << "Usage: " << argv[0] << " project-id location-id\n";
    return 1;

  auto const location = google::cloud::Location(argv[1], argv[2]);

  namespace tasks = ::google::cloud::tasks_v2;
  auto client = tasks::CloudTasksClient(tasks::MakeCloudTasksConnection());

  for (auto queue : client.ListQueues(location.FullName())) {
    if (!queue) throw std::move(queue).status();
    std::cout << queue->DebugString() << "\n";

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

Main classes

The main class in this library is tasks_v2::CloudTasksClient. All RPCs are exposed as member functions of this class. Other classes provide helpers, configuration parameters, and infrastructure to mock tasks_v2::CloudTasksClient when testing your application.
