In some cases, you may need to override the default endpoint used by the client library. Use theEndpointOptionwhen initializing the client library to change this default.
For example, this will override the default endpoint foriot_v1::DeviceManagerClient:
// This configuration is common with Private Google Access:
// https://cloud.google.com/vpc/docs/private-google-access
auto options = google::cloud::Options{}.set<google::cloud::EndpointOption>(
"private.googleapis.com");
auto client = google::cloud::iot_v1::DeviceManagerClient(
google::cloud::iot_v1::MakeDeviceManagerConnection(options));
