Connect Telegram Bot to Google Sheets

This video explains all steps in detail: https://www.youtube.com/watch?v=24EyItKfm50&list=PLGGHwNnXfci86dfqIVLc5l391SPk-RX1F

Step 1: Setting up the Telegram Bot

Go to Telegram for Web
Search for BotFather
Use /newbot to create a bot. This will give you an access token to use in your script. For further Telegram information, RTFM at (https://core.telegram.org/bots/api)

Step 2: Setting up Google Apps Script

Create a new Google Sheet in Google Drive. Go to script editor (Tools > Script Editor) and paste the code into the newly created code.gs file. Once done, deply the script as a web application. You will get a URL to use in the code.gs file.

Run getMe() and setWebhook() to initialise the integration.

Step 3: Add your Spreadsheet ID to the Script

Find your Google Sheet ID in the URL: https://docs.google.com/spreadsheets/d/{ID_HERE}/edit and past it into the code.gs file.

Step 4: Add your Telegram ID to the Script for error catching

After you seccusfully communicated with the bot, your chat ID should be in the recording spreadsheet entries. Copy and past this into the adminID variable in the script

2. Create OpenAI ChatGPT like bot in Telegram (openai.gs)

openai.gs

A simple Google Apps Script that provides an output to a user input in Telegram, and saving the question + answer + error (if applicable) to a Google Sheet. Please note that this script can not (yet) 'remember' the conversation or take feedback to previous questions. It will evaluate a single inout with a single output. This script will serve as a starting point for those who want to add extra functionality, and I welcome you to add features with pull requests.

The script starts by defining a list of allowed user IDs that are authorized to chat with the bot, as well as some constants such as the bot token, OpenAI API key, and Spreadsheet ID.

The script uses the completions API enpoint with the text-davinci-003 set to max_tokens = 100.

Below is an example of the Telegram Chat and response:

Below is an example of the questions and answers saved to Google Sheets:

Script Inputs:

ALLOWED_USER_IDS: A list of user IDs that are allowed to chat with the bot
BOT_TOKEN: Script Property with key bot_token defined in Settings > Script Properties. Get this from @BotFather in Telegram
OPENAI_API_KEY: Script Property with key openai_api_key defined in Settings > Script Properties. Get this from https://beta.openai.com/account/api-keys
SPREADSHEET_ID: To get this, go to your sheet URL and grab the id from here: https://docs.google.com/spreadsheets/d/{ID_HERE}/edit
WEBHOOK_URL: After deploying the script as web app, copy the URL and paste it here

The script then includes a number of functions that handle different tasks:

getMe: Sends a request to the Telegram API to get information about the bot.
setWebhook: Sends a request to the Telegram API to set up a webhook for the bot.
doPost: Handles webhook requests from Telegram. This function is called whenever the bot receives a message from a user. It parses the request body, gets the message from the request, and writes the question to the 'question' column in a Google Sheets document. It then sends the question to the OpenAI API using the sendToOpenAI function, writes the answer to the 'answer' column in the Google Sheets document, and sends the answer back to the Telegram chat using the sendToTelegram function.

The script also includes the following functions:

sendToOpenAI: Sends a request to the OpenAI API with the specified text and returns the response.
sendToTelegram: Sends a message to the specified Telegram chat with the specified text.
writeToSheet: Writes the specified text to the specified column in the Google Sheets document.

🚨 Please Note 🚨

I'm not entirely sure if it's the best idea to define sensitive data in the Script Properties section of Google Apps Script. Please be aware of this.
