Google App script - Telegram Bot - Inline Keyboard callback_query - google-apps-script

Question

This here is my function that hears for anything incoming from Telegram. It does work well with any message and files or whatever but it doesn't work when i press a but of an inline_keyboard, Why?
How can i create a function that hears for a inline_keyboard button pressed?
function doPost(e) {
var data = JSON.parse(e.postData.contents);
sendText('personal_chat_id', JSON.stringify(data));
}
In case you need it here under is my function that can send a message with an inline_keyboard.
function lol(){
var keyboard ={
inline_keyboard: [
[
{
text: "A",
callback_data: 123
},
{
text: "B",
callback_data: 234
}
],
[
{
text: "C",
callback_data: 345
},
{
text: "D",
callback_data: 456
}
]
]
}
sendText('personal_chat_id', "lol", keyboard)
}
function sendText(chatId,text,keyBoard){
keyBoard = keyBoard || 0;
if(keyBoard.inline_keyboard || keyBoard.keyboard){
var data = {
method: "post",
payload: {
method: "sendMessage",
chat_id: String(chatId),
text: text,
parse_mode: "HTML",
reply_markup: JSON.stringify(keyBoard)
}
}
}
var response = UrlFetchApp.fetch('https://api.telegram.org/bot' + token + '/', data);
return response.getContentText()
}

You need to do it inside the doPost(e) function. Take the "e" parameter and verify what kind of type it is. If it is "contents.callback_query" is coming from the inline keyboard response and if it is "contents.message" it's text typed by the user.
And dont forget declare sendText() and sendKeyboard() functions.
function doPost(e) {
var contents = JSON.parse(e.postData.contents);
var keyboard = {
"inline_keyboard": [
[{
"text": "Players",
"callback_data": "player"
}],
[{
"text": "Match",
"callback_data": "match"
}],
[{
"text": "Results",
"callback_data": "result"
}]
]}
if (contents.callback_query) {
var id = contents.callback_query.message.chat.id;
var text = contents.callback_query.data;
switch (text) {
case 'Player':
var answer = 'Ingresa tu nombre y apellido';
sendText(id, answer);
break;
case 'match':
var answer = 'Ingresá tu nombre y apellido';
sendText(id, answer);
break;
case 'result':
var keyboard = {
'inline_keyboard': [
[{
'text': 'Youtube',
'url': 'https://youtube.com'
},{
'text': 'Google',
'url': 'https://google.com'
}]
]
};
sendTextWithButtons(id, 'Algunos enlaces', JSON.stringify(keyboard));
break;
default:
var answer = 'Default answer';
sendText(id, answer);
break;
}
var chat_id = contents.callback_query.from.id;
var user = contents.callback_query.message.chat.first_name;
var cb_data = contents.callback_query.data;
sendText(chat_id, CariDataDariIDSheet(cb_data));
}else if (contents.message) {
var chat_id = contents.message.from.id;
var user = contents.message.chat.first_name;
var answer = "your answer";
sendKeyboard(chat_id, answer, keyboard);
}
}
