name	type	Description
bot_token	String	The Telegram Bot Token
method	String	Telegram Bot API method name e.g. sendMessage
args	JSON Object	The arguments/params for the API method e.g. {"chat_id":"123","text":"HelloWorld"}

How to Deploy

  }  
}

function requestHandler(e){
  var res = handleRequest(e);
  return ContentService.createTextOutput(res);
}

function handleRequest(e) {
  if(typeof e.parameter.bot_token === 'undefined'){
    return 'Error! Bot token not provided';
  } else if(typeof e.parameter.method === 'undefined') {
    return 'Error! Method name not provided';
  }
  var bot_token = e.parameter.bot_token;
  var tg_method = e.parameter.method;
  
  var data = {
    "method": "post",
    "muteHttpExceptions": true
  }
  if(typeof e.parameter.args !== 'undefined'){
    var args = e.parameter.args;
    data.payload = JSON.parse(args);

Thank you so much.
Worked for me.

function doGet(e){
var options = {
'method' : 'post',
'contentType': 'application/json',
// Convert the JavaScript object to a JSON string.
'payload' : e.postData.contents,
'muteHttpExceptions' : true
};
var response = UrlFetchApp.fetch('%webhook%', options);
Logger.log(response.getContentText());
}

function doPost(e){
var options = {
'method' : 'post',
'contentType': 'application/json',
'payload' : e.postData.contents,
'muteHttpExceptions' : true
};
var response = UrlFetchApp.fetch('%webhook%', options);
Logger.log(response.getContentText());
}

TypeError: Cannot read property 'postData' of undefined
