How to get Client API Key on DialogFlow?

Question

Python

There is a DialogFlow service.
The article https://habr.com/ru/post/346606/ states that it is necessary to use the api key.
But he's not there. As I understand it, the principle of providing access to the service has changed and now it is necessary to generate access through the google cloud.
Maybe someone did similar projects and can tell you how to work with this service using the apiai module in python?
