A Telegram Chatbot for Kanboard with NodeRED


I've used a number of todo list applications over the years.

I have recently decided to use a simple kanban with three columns (todo/wip/done) as my todo list, and it works wonders.

I self-host a Kanboard instance, so I have full control over my lists.

In my article about my desktop environment, I cover how I even integrated Kanboard in my i3 bar.

I no longer depend on some vendor that could shut down the service as they please.

Obviously, mobile apps are the strong point of proprietary solutions, while the Android app for Kanboard is not as advanced.

I wanted to implement an easy way to add tasks to my Kanboard, so how about using a Telegram bot?

Here we go!


  • a Kanboard instance, obviously
  • an API token for Kanboard (Settings > API)
  • a NodeRED instance
  • node-red-contrib-telegrambot version 7.1.1+
  • a Telegram account

The workflow

Create the bot

Use BotFather to create your new bot.

Configure the bot:


The query to Kanboard API should be done with the http request node:

getAllTasks node:

msg.chatId = msg.payload.chatId;
var item = msg.payload.content.replace(/^\s+/g, '');
msg.payload = "{\"jsonrpc\": \"2.0\", \"method\": \"getAllTasks\", \"id\": 1, \"params\": {\"project_id\": 6}}";
return msg;

createTask node:

Change the project ID number.

msg.chatId = msg.payload.chatId;
msg.item = msg.payload.content.replace(/^\s+/g, '');
msg.payload = "{\"jsonrpc\": \"2.0\", \"method\": \"createTask\", \"id\": 1, \"params\": {\"title\": \"" + msg.item + "\", \"project_id\": 6}}";
return msg;

Generate the reply list:

Change the column ID.

var items = msg.payload.result;

msg.payload.chatId = msg.chatId;
msg.payload.type = 'message';
msg.task = [];

// this will generate an array with "null" for tasks not in column 20
for(var i = 0; i < items.length; i++) {
   if(items[i].column_id === '20') {
     msg.task[i] = "- " + items[i].title + "\n";

// remove null entries
msg.cleaned = msg.task.filter(n => n)
// turn array into string
var list = msg.cleaned.join("");
// message
if(list === "") {
    msg.payload.content = "Nothing in the list."
} else {
msg.payload.content = list;

return [ msg ];

Generate the reply todo:

If you make your board public, you can share in the reply.

msg.payload.chatId = msg.chatId;
msg.payload.type = 'message';
msg.payload.content = 'Added "'+ msg.item + '" to your todo list.\n\nFull list at https://kanban.example.org/public/board/XXX';
return [ msg ];
