An idiomatic C++ client library forSecret Manager API, a service that stores sensitive data such as API keys, passwords, and certificates.
While this library isGA, please note that the Google Cloud C++ client libraries donotfollowSemantic Versioning.

All RPCs are exposed as member functions of this class. Other classes provide helpers, configuration parameters, and infrastructure to mock [`secretmanager_v1::SecretManagerServiceClient`](/cpp/docs/reference/secretmanager/latest/classgoogle_1_1cloud_1_1secretmanager__v1_1_1SecretManagerServiceClient) when testing your application.\n\n### More Information\n\n- [Error Handling](https://cloud.google.com/cpp/docs/reference/common/latest/common-error-handling.html) - describes how the library reports errors.\n- [How to Override the Default Endpoint](/cpp/docs/reference/secretmanager/latest/secretmanager-override-endpoint) - describes how to override the default endpoint.\n- [How to Override the Authentication Credentials](/cpp/docs/reference/secretmanager/latest/secretmanager-override-authentication) - describes how to change the authentication credentials used by the library.\n- [Override Retry, Backoff, and Idempotency Policies](/cpp/docs/reference/secretmanager/latest/secretmanager-override-retry) - describes how to change the default retry policies.\n- [Environment Variables](/cpp/docs/reference/secretmanager/latest/secretmanager-env) - describes environment variables that can configure the behavior of the library."]]
