telegram bot keyboard with google apps script - google-apps-script

Question

I want to meet new clients in telegram bot with a keyboard buttons
So far I have this code written in Google Apps Script, but in result there is nothing.
function doPost(e) {
var API_TOKEN = 'bla-bla-bla';
var update = JSON.parse(e.postData.contents);
if (update.hasOwnProperty('message')) {
var msg = update.message;
var chatId = msg.chat.id;
if (msg.text == '/start') {
function sendText(chatId, text, keyboard) {
var payload = {
'method': 'sendMessage',
'chat_id': String(chatId),
'text': "Hello",
'parse_mode': 'HTML',
reply_markup: JSON.stringify({
keyboard: [
[
"A",
"B"
],
[
"C",
"D"
]
],
resize_keyboard: true,
one_time_keyboard:true
})
}
var data = {
"method": "post",
"payload": payload
}
UrlFetchApp.fetch('https://api.telegram.org/bot' + API_TOKEN + '/', data);
}
}
}
}
Is this a missing feature or it's me, doing something wrong?

Answer 1

You probably want something like this?
PS: replace it with your chat id
function testKeyboard() {
const chatId = YOURCHATID; // REPLACE THIS
const choices = ['Mozzarella','Gouda cheese','Camembert','Gorgonzola','Cheddar Cheese'];
const text = 'Make your choice';
sendKeyboard(chatId, choices, text);
}
You can do it with this code.
PS: replace token with your bot's token
const token = ''; // REPLACE IT WITH YOUR BOTS TOKEN
const telegramApi = 'https://api.telegram.org/bot' + token;
function sendKeyboard(chatId, choices, text = 'Menu') {
const buttons = transformArrayToKeyboard(choices);
const replyKeyboardMarkup = {keyboard: buttons,
one_time_keyboard: true,
resize_keyboard: true};
const replyMarkup = JSON.stringify(replyKeyboardMarkup);
const url = telegramApi + '/sendMessage?chat_id=' + encodeURIComponent(chatId) + '&text=' + encodeURIComponent(text) + '&disable_web_page_preview=true&reply_markup=' + encodeURIComponent(replyMarkup);
const response = UrlFetchApp.fetch(url);
Logger.log(response.getContentText());
}
function transformArrayToKeyboard(choices) {
const maxLengthRowKeyboardMenu = 3;
const arr = choices.map(item => ({text: item }));
const result = [];
let index = 0;
while(arr.slice(index).length > 0) {
const newRowValuesForButtons = arr.slice(index,index+maxLengthRowKeyboardMenu);
result.push(newRowValuesForButtons);
index += maxLengthRowKeyboardMenu;
}
return result;
}
// function transformArrayToKeyboard transforms [4,5,6,7,8] to:
// [
// [
// {text: "4" },{text: "5" },{text: "6" }
// ]
// [
// {text: "7" },{text: "8" }
// ]
// ];
