Cloud Data Loss Prevention (DLP) API C++ Client Library

An idiomatic C++ client library for the Cloud Data Loss Prevention (DLP) API, a service that provides methods for detection, risk analysis, and de-identification of privacy-sensitive fragments in text, images, and Google Cloud Platform storage repositories.

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/dlp/quickstart/ directory, which should give you a taste of the Cloud Data Loss Prevention (DLP) API C++ client library API.

#include "google/cloud/dlp/v2/dlp_client.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;

  namespace dlp = ::google::cloud::dlp_v2;
  auto client = dlp::DlpServiceClient(dlp::MakeDlpServiceConnection());

  auto const location =
      "projects/" + std::string(argv[1]) + "/locations/" + std::string(argv[2]);
  for (auto r : client.ListStoredInfoTypes(location)) {
    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

The main class in this library is dlp_v2::DlpServiceClient. All RPCs are exposed as member functions of this class. Other classes provide helpers, configuration parameters, and infrastructure to mock dlp_v2::DlpServiceClient when testing your application.
