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

I have the same issue few months ago, check this, this is how i solve it. From your JSON that Google Cloud extract this lines.

const dialogflow = require('dialogflow');
const LANGUAGE_CODE = 'en-US'
const projectId = 'projectid';
const sessionId = 'sessionId';
const query = 'text to check';


let privateKey = "private key JSON";
let clientEmail = "email acount from JSON";
let config = {
credentials: {
    private_key: privateKey,
    client_email: clientEmail
}
};

sessionClient = new dialogflow.SessionsClient(config);

async function sendTextMessageToDialogFlow(textMessage, sessionId) {
// Define session path
const sessionPath = this.sessionClient.sessionPath(projectId, sessionId);
// The text query request.
const request = {
    session: sessionPath,
    queryInput: {
        text: {
            text: textMessage,
            languageCode: LANGUAGE_CODE
        }
    }
}
try {
    let responses = await this.sessionClient.detectIntent(request)
    console.log('DialogFlow.sendTextMessageToDialogFlow: Detected intent', responses);
    return responses
} catch (err) {
    console.error('DialogFlow.sendTextMessageToDialogFlow ERROR:', err);
    throw err
}
};


sendTextMessageToDialogFlow(query, sessionId)
