Fina Bot is a financial assistance bot designed to help manage your finances.

These instructions will get you a copy of the project up and running on your local machine for development and testing purposes.

• Python - The programming language used.
• Google Sheets API - Used to store and retrieve data.

This is the main entry point of the application.

This Python script uses the Flask web framework to create a webserver interact with Facebook's Messenger Platform. Here's a breakdown of what each part does:

from flask import Flask, request
from api import get_and_response

app = Flask(__name__)
app.debug = True

ALLOWED_USER = ['6913965595292111']

This part imports necessary modules and sets up a new Flask web application. ALLOWED_USER is a list of user IDs that are allowed to interact with the bot.

@app.route("/", methods=['GET'])
def fbverify():
    ...

This function handles GET requests to the root URL ("/"). It's used by Facebook to verify your webhook. Facebook sends a GET request with specific parameters, and your server must respond correctly to verify the webhook.

@app.route("/", methods=['POST'])
def fbwebhook():
    ...

This function handles POST requests to the root URL. These requests are sent by Facebook when a user sends a message to your bot. The function extracts the sender ID and message text from the request, and passes them to get_and_response to generate a response.

if __name__ == "__main__":
    app.run(debug=True, port=3000)

This part runs the Flask server when the script is run directly (not imported as a module). The server runs in debug mode on port 3000.

from datetime import datetime
import locale

from controllers.google.google_utils import * # Import all functions from google_utils.py
import controllers.messenger.messenger_utils as messenger_utils

locale.setlocale(locale.LC_ALL, 'vi_VN') # Set locale to Vietnamese

The above code imports necessary modules and sets the locale to Vietnamese.

COMMANDS = [
  "CONNECT",  # Check Messenger connection
  "GET",      # Add income
  "SPEND",    # Add expense
  "BALANCE"   # Get balance
  ]

The COMMANDS list contains all the commands that the bot can handle.

try: 
  creds = create_creds()
  service = build_service(creds)
  print("Service built successfully")
except Exception as e:
  print(f'Error occured while building service with error: {e}')

The above code tries to create credentials and build the service for Google Sheets. If there's an error, it prints the error message.

def fetch_balance():
  ...
def get_income(text: str):
  ...
def spend_income(text: str):
  ...

These functions handles BALANCE, GET, SPEND commands

def get_and_response(sender_id, text):
  ...

The get_and_response function processes the command from the user and sends a response back.
