Dialogflow easy way for authorization

Question

Does exist an easy way to connect Dialogflow agent to node.js code? When I use this code with the correct projectID taken from the Dialogflow agent\'s settings

Answer 1

It is not very well documented, but the easiest way to authenticate is using the JSON file provided on your google cloud platform console.

const sessionClient = new dialogflow.SessionsClient({
    keyFilename: '/path/to/google.json'
});
const sessionPath = sessionClient.sessionPath(projectId, sessionId);

This also works for all the other clients. ContextsClients, EntityTypesClient and so on.
