reCAPTCHA Enterprise API C++ Client Library

This directory contains an idiomatic C++ client library for the reCAPTCHA Enterprise API. This service helps protect your website from fraudulent activity, spam, and abuse without creating friction.

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

Quickstart

The quickstart/ directory contains a minimal environment to get started using this client library in a larger project. The following "Hello World" program is used in this quickstart, and should give you a taste of this library.

#include "google/cloud/recaptchaenterprise/v1/recaptcha_enterprise_client.h"
#include "google/cloud/project.h"
#include <iostream>

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

  namespace recaptchaenterprise = ::google::cloud::recaptchaenterprise_v1;
  auto client = recaptchaenterprise::RecaptchaEnterpriseServiceClient(
      recaptchaenterprise::MakeRecaptchaEnterpriseServiceConnection());

  auto const project = google::cloud::Project(argv[1]);
  for (auto r : client.ListKeys(project.FullName())) {
    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;
}
