Using a webhook from Google Cloud Functions with Dialogflow CX - google-cloud-functions

Question

I managed to successfully implement a webhook with Dialogflow CX in a repl environment and flask, but not sure how to move the webhook onto Google Cloud Functions. I've scoured the web for a tutorials, but most are in Dialogflow ES. Any help is appreciated!
This is my current code on repl:
from flask import Flask, request
app = Flask(__name__)
def create_json_response(response_text, updated_params):
jsonResponse = {
"fulfillment_response":
{
"messages": [
{
"text": {
"text": [
str(response_text)
]
}
}
]
},
"sessionInfo": {
"parameters": updated_params
}
}
return jsonResponse
#app.route('/webhook', methods=['POST'])
def webhook():
req = request.get_json(silent=True, force=True)
fulfillmentInfo = req.get('fulfillmentInfo')
if fulfillmentInfo['tag'] == 'add':
updated_params = {}
total = 0
num1 = int(req.get('sessionInfo').get('parameters').get('number'))
num2 = int(req.get('sessionInfo').get('parameters').get('number1'))
total = str(num1 + num2)
updated_params['previous1'] = num1
updated_params['previous2'] = num2
updated_params['number'] = None
updated_params['number1'] = None
jsonResponse = create_json_response(total, updated_params)
return jsonResponse
elif fulfillmentInfo['tag'] == 'multiply':
updated_params = {}
total = 0
num1 = int(req.get('sessionInfo').get('parameters').get('number'))
num2 = int(req.get('sessionInfo').get('parameters').get('number1'))
total = str(num1 * num2)
updated_params['previous1'] = num1
updated_params['previous2'] = num2
updated_params['number'] = None
updated_params['number1'] = None
jsonResponse = create_json_response(total, updated_params)
return jsonResponse
#app.route('/') # this is the home page route
def hello_world(): # this is the home page function that generates the page code
return "Hello Beautiful World!"
if __name__ == '__main__':
app.run(host='0.0.0.0', port=8080) # This line is required to run Flask on repl.it

I'm answering my own question! I just needed to pass request as a parameter in my webhook function. Derp!
