    ]
    magic_eight_ball_response = random.choice(choices)
    logging.info(magic_eight_ball_response)
    return make_response(jsonify({'fulfillmentText': magic_eight_ball_response }))

• Make sure to replace line 6 of main.py file with your entry point name as provided to you

• replace requirements.txt with this

google-cloud-translate
google-cloud-logging

• Fulfillment -> Enable Webhook -> Paste your trigger url of your cloud function -> Save Copy the Link from your cloud functions

Go to Integrations -> Try Actions Builder -> Enable web activity if not enabled

-> Test Your App with google assistant , it is available on action console press talk to start

Task 3: Add multilingual support to your Cloud Function

Goto your cloud function and change the main.py add this lines after line 13

    request_json = request.get_json()
    if request_json and 'queryResult' in request_json:
        question = request_json.get('queryResult').get('queryText')
    # try to identify the language
    language = 'en'
    translate_client = translate.Client()
    detected_language = translate_client.detect_language(question)
    if detected_language['language'] == 'und':
        language = 'en'
    elif detected_language['language'] != 'en':
        language = detected_language['language']
    # translate if not english
    if language != 'en':
        logging.info('translating from en to %s' % language)
        translated_text = translate_client.translate(
             magic_eight_ball_response, target_language=language)
        magic_eight_ball_response = translated_text['translatedText']

final code will look like this

Go to Integrations -> Try Actions Builder -> -> Test You App with google assitant with this commands

Text you assistant with this commands
