Answer 1

In order to use the Dialogflow API (in this case, list all the entity types in the specified agent) you have to:

1. Enable the Dialogflow API for your project
2. Go to the Create service account key page. From the Service account list, select New service account , enter a name in the Service account name field.
3. From the Role list, select Project > Owner.
4. Click Create . A JSON file that contains your key downloads to your computer.
5. Once you have the JSON file, you need to set an environment variable in a shell session GOOGLE_APPLICATION_CREDENTIALS="/path/to/key.json" .

You can access the API via REST , gRPC or a client library . In this repository, there are some samples with the python client library.
