While you can use Dialogflow by making direct REST over HTTP requests,
we provide client libraries for several popular languages.
Google Cloud Client Libraries
Dialogflow client libraries are built on
Google Cloud Client Libraries.
This common infrastructure provides functionality for API-specific library implementations,
but it also provides types and methods that you may use directly when using any Cloud API.
Authentication and access control
The Dialogflow quickstart guides provide basic information
on authentication and access control.
