        elif text[0].lower() == 'time':
            return self.time(chatID)

Flask

To process incoming messages to our server

from flask import Flask, request, jsonify
from ultrabot import ultraChatBot
import json

app = Flask(__name__)

@app.route('/', methods=['POST'])
def home():
    if request.method == 'POST':
    bot = ultraChatBot(request.json)
    return bot.Processingـincomingـmessages()

if(__name__) == '__main__':
    app.run()

We will write the path app.route('/', methods = ['POST']) for it. This decorator means that our home function will be called every time our FLASK server .
