scheduling facebook chatbot to speak at a certain time of the day in Flask - facebook

Question

Below an chatbot app; the app is working well and the bot answer maybe to every message; i would like the chat bot to speak to the user everyday at 3pm; i use "schedule" at the end of the code to start the function hello;
The all thing just does not work and i don't get any error; the python is loading infinitely;
from what i understand, there would be 2 infinite loop, the one for python and the one for scheduling; So would i need to use concurrency or something like this ?
from flask import Flask, request
import requests
import time
import schedule
from datetime import datetime
app = Flask(__name__)
FB_API_URL = 'https://graph.facebook.com/v2.6/me/messages'
VERIFY_TOKEN = "blabla"
PAGE_ACCESS_TOKEN = "blabla"
def Hello(message):
return "Hello, how are you doing today '{}'".format(message)
def get_bot_response(message):
"""this is a dummy response to what the user says."""
return "maybe '{}'".format(message)
def verify_webhook(req):
if req.args.get("hub.verify_token") == VERIFY_TOKEN:
return req.args.get("hub.challenge")
else:
return "incorrect"
def respond(sender, message):
response = get_bot_response(message)
send_message(sender, response)
def is_user_message(message):
"""Check if the message is a message from the user"""
return (message.get('message') and
message['message'].get('text') and
not message['message'].get("is_echo"))
#app.route("/webhook",methods=['GET','POST'])
def listen():
"""This is the main function flask uses to
listen at the `/webhook` endpoint"""
if request.method == 'GET':
return verify_webhook(request)
if request.method == 'POST':
payload = request.json
event = payload['entry'][0]['messaging']
for x in event:
if is_user_message(x):
text = x['message']['text']
sender_id = x['sender']['id']
respond(sender_id, text)
return "ok"
def send_message(recipient_id, text):
"""Send a response to Facebook"""
payload = {
'message': {
'text': text
},
'recipient': {
'id': recipient_id
},
'notification_type': 'regular'
}
auth = {
'access_token': PAGE_ACCESS_TOKEN
}
response = requests.post(
FB_API_URL,
params=auth,
json=payload
)
return response.json()
if __name__ == "__main__":
app.run(port=5000)
schedule.every().sunday.at("15:00").do(hello)
