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 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());
}
