# How to Override the Default Universe Domain

3.7.0-rc 3.6.0 (latest) 3.5.0 3.4.0 3.3.0 3.2.0 2.48.0-rc 2.47.1 2.46.0 2.45.0 2.44.0 2.43.0 2.42.0 2.41.0 2.40.0 2.39.0 2.38.0 2.37.0 In some cases, you may need to override the default universe domain used by the client library. Use `AddUniverseDomainOption` when initializing the client library to change this default.

For example, this will override the default universe domain for `storagebatchoperations_v1::StorageBatchOperationsClient`:

      google::cloud::Options options;

      // AddUniverseDomainOption interrogates the UnifiedCredentialsOption, if set,
      // in the provided Options for the Universe Domain associated with the
      // credentials and adds it to the set of Options.
      // If no UnifiedCredentialsOption is set, GoogleDefaultCredentials are used.
      auto ud_options = google::cloud::AddUniverseDomainOption(std::move(options));

      if (!ud_options.ok()) throw std::move(ud_options).status();
      auto ud_client =
          google::cloud::storagebatchoperations_v1::StorageBatchOperationsClient(
              google::cloud::storagebatchoperations_v1::
                  MakeStorageBatchOperationsConnection(*ud_options));
