Saving Telegram Bot messages into google spreadsheet - google-apps-script

Question

I'm a beginner, so I'll try my best to explain what happends in the code and what I want to do. I've created a telegram bot and I want to save all the message log into google spreadsheets. I'm using Google App Scripts for this. The problem is that when I'm using the following code, only the messages that I write are saved into google sheets, it happends in the "doPost" function. What I want to do is to save also the messages I receive from the bot. I tried adding the same code the I used in "doPost" and worked into the function "sendText" but I'm still unable to save the messages that the bot sends. How can I do this? here's my code:
var token = "..."; // 1. FILL IN YOUR OWN TOKEN
var telegramUrl = "https://api.telegram.org/bot" + token;
var webAppUrl = "..."; // 2. FILL IN YOUR GOOGLE WEB APP ADDRESS
var ssId = "..."; // 3. FILL IN THE ID OF YOUR SPREADSHEET
var adminID = "..."; // 4. Fill in your own Telegram ID for debugging
// connect to bot
function getMe() {
var url = telegramUrl + "/getMe";
var response = UrlFetchApp.fetch(url);
Logger.log(response.getContentText());
}
function setWebhook() {
var url = telegramUrl + "/setWebhook?url=" + webAppUrl;
var response = UrlFetchApp.fetch(url);
Logger.log(response.getContentText());
}
// make the bot to send a message
function sendText(id,text) {
var url = telegramUrl + "/sendMessage?chat_id=" + id + "&text=" + encodeURIComponent(text);
var response = UrlFetchApp.fetch(url);
Logger.log(response.getContentText());
try {
// this is where telegram works
var data = JSON.parse(response.getContentText());
var text = data.message.text;
var id = data.message.chat.id;
var name = data.message.chat.first_name + " " + data.message.chat.last_name;
var answer = "Hi " + name;
// sendText(id,answer);
SpreadsheetApp.openById(ssId).getSheets()[0].appendRow([new Date(),id,name,text,answer]);
if(/^#/.test(text)) {
var sheetName = text.slice(1).split(" ")[0];
var sheet = SpreadsheetApp.openById(ssId).getSheetByName(sheetName) ? SpreadsheetApp.openById(ssId).getSheetByName(sheetName) : SpreadsheetApp.openById(ssId).insertSheet(sheetName);
var newText = text.split(" ").slice(1).join(" ");
sheet.appendRow([new Date(),id,name,newText,answer]);
sendText(id,"your text '" + newText + "' is now added to the sheet '" + sheetName + "'");
}
} catch(e) {
sendText(adminID, JSON.stringify(e,null,4));
}
}
function doGet(e) {
return HtmlService.createHtmlOutput("Hi there");
}
// send a message from me to the bot
function doPost(e) {
try {
// this is where telegram works
var data = JSON.parse(e.postData.contents);
var text = data.message.text;
var id = data.message.chat.id;
var name = data.message.chat.first_name + " " + data.message.chat.last_name;
var answer = "Hi " + name;
// sendText(id,answer);
SpreadsheetApp.openById(ssId).getSheets()[0].appendRow([new Date(),id,name,text,answer]);
if(/^#/.test(text)) {
var sheetName = text.slice(1).split(" ")[0];
var sheet = SpreadsheetApp.openById(ssId).getSheetByName(sheetName) ? SpreadsheetApp.openById(ssId).getSheetByName(sheetName) : SpreadsheetApp.openById(ssId).insertSheet(sheetName);
var newText = text.split(" ").slice(1).join(" ");
sheet.appendRow([new Date(),id,name,newText,answer]);
sendText(id,"your text '" + newText + "' is now added to the sheet '" + sheetName + "'");
}
} catch(e) {
sendText(adminID, JSON.stringify(e,null,4));
}
}
Thank you.
