My bot can't get 'new_chat_members' event - only working for bots created with botfather for testing, not real users

[bluetyphoon77]

Hi guyz, My bot can't get 'new_chat_members' event - only working with test-bots created on my account with botfather for testing, not with real users joining the group. Any idea why ???

I use the bot.on('new_chat_members', (msg) => { ...

Thanks in advance for your advices @VDS13 @Sidelux Could you help ? thanks in advance Y.

Hello. Are administrator rights granted to the bot?

[VDS13]

Without administrator rights, it does not track this event.

[bluetyphoon77]

Hi @VDS13 😊🙏 thanks for your answer. My bot is already Admin in the group where I added it. You mean I have to set something in botfather?

And do you know why it works perfectly for test bots created under my account and joining the group, but not with other users?

[bluetyphoon77]

Hello. Are administrator rights granted to the bot?

Yes they already are

[VDS13]

Is the group public or private?

[bluetyphoon77]

@VDS13 Hey Dmitry, it is public

[VDS13]

Strange. Let's summarize: a bot with administrator rights, a public group, not a supergroup, new_chat_members works on your bots, but not on users?

[bluetyphoon77]

yes exactly ! i agree it is weird :) here is the group: https://t.me/Souffles_Magiques

Show a piece of code from the beginning to the new_chat_members event handler.

[dev-anshu]

bot.on('new_chat_members', (msg) => { console.log(msg) } });

nothing is coming. I want channel id through my bot like https://t.me/username_to_id_bot bot is doing.

[VDS13]

There are no others in the code before this handler (let's say bot.on('message', ...))?

[dev-anshu]

const TelegramBot = require('node-telegram-bot-api'); const token = '<bot_token>';

const bot = new TelegramBot(token, { polling: true }); bot.on('message', (msg) => { console.log(msg) } });

I am trying to get channel_id when my bot joins any channel. how can I do it? can you give me any solution

[VDS13]

If your message handler comes before new_chat_members, then try swapping them. That is:

const TelegramBot = require('node-telegram-bot-api');
const token = '<bot_token>';

const bot = new TelegramBot(token, { polling: true });
bot.on('new_chat_members', (msg) => {
     console.log(msg)
});
bot.on('message', (msg) => {
     console.log(msg)
});

[dev-anshu]

Still not working, I am getting message when i send to bot, but while adding bot to any channel I am not getting any channel_id, new-chat_members not working. This is working for groups but not channels.

[bluetyphoon77]

Hi @VDS13 Here is a test code using what I use:

import TelegramBot from 'node-telegram-bot-api';

// Replace 'YOUR_BOT_TOKEN' with your actual bot token const bot = new TelegramBot('xxxxxxxxxxxxxxx', { polling: true });

// Event handler for new chat members bot.on('new_chat_members', (msg) => { console.log('New user event triggered'); console.log('New chat members:', msg.new_chat_members);

// Process new members processNewMembers(msg.new_chat_members); });

// Function to process new members const processNewMembers = (newMembers) => { newMembers.forEach((member) => { console.log('New member:', member); // Perform any additional processing here }); };

// Event handler for messages bot.on('message', (msg) => { console.log('Received message:', msg.text); });

// Start the bot console.log('Bot is running...');

[bluetyphoon77]

Obviously I'm not the only one with this problem. Telegram maybe changed something and your event handler has to be updated ?

[bluetyphoon77]

@dev-anshu for me adding a test bot created with botfather is working ! Event is triggerd. But any other bot or real user not.

[Sp3rick]

that's weird, anyway you can try go to botFather, use /mybots -> select your bot -> Gruop Privacy -> Turn off

[bluetyphoon77]

Hi @Sp3rick Thanks for your help. I did it but it did not work.

@VDS13 Do you, or anyone reading this, succeed with the code i provided in a group of yours ?

Are you sure events from library are up to date?

[bluetyphoon77]

Is there any dev knowing if the code is still working ? @yagop @GochoMugo @kamikazechaser @danielperez9430 ? Cheeers

So now, use "chat_member" for know if user join or left.

This warning is from 3 years ago, so maybe now is deprecated for normal users.

You can try the following, it works for me. It detects both input and output in groups.

let TelegramBot = require('node-telegram-bot-api');
let bot = new TelegramBot('YOUR_TOKEN', { "polling": true })

bot.on('chat_member', (memberStatus) => {
  console.log(memberStatus)
})

This code would return something similar to the following image

[bluetyphoon77]

Thanks for your answers @danielperez9430 and @IscoV 😊👍 I just used your code @IscoV but bot does not see nor any user nor any bot now.

When have you tested those lines of code? In a group? Why would my bot not see anything and yours yes? Cheers

Ps: node-telegram-bot version is 0.64.0

[bluetyphoon77]

I used:

let TelegramBot = require ('node-telegram-bot-api');

// Replace 'YOUR_BOT_TOKEN' with your actual bot token let bot = new TelegramBot('XXXX', { polling: true });

// Event handler for new chat members bot.on('chat_member', (memberStatus) => { console.log('User event triggered'); //console.log(memberStatus); let {chat, from, date, old_chat_member, new_chat_member } = memberStatus; console.log("Chat: ", chat); console.log("From: ", from); console.log("Date: ", date); console.log("Old Member: ", old_chat_member); console.log("New Member: ", new_chat_member);

});

// Start the bot console.log('Bot is running...');

At the time of execution, it should not show anything. It should only show the information when adding or joining a user/bot to the group.

@IscoV Yes yes, I'm talking about this. I added a bot and a user joined for testing. Nothing shows. Have you tested it now on your group ?

@IscoV Yes yes, I'm talking about this. I added a bit and a user joined for testing. Nothing shows. Have you tested it now on your group ?

I tested it before sending it. Else, try to enable the update manually.

Paste the following URL in your browser and replace the YOUR_BOT_TOKEN

https://api.telegram.org/bot<YOUR_BOT_TOKEN>/getUpdates?allowed_updates=["update_id","message","edited_message","channel_post","edited_channel_post","inline_query","chosen_inline_result","callback_query","shipping_query","pre_checkout_query","poll","poll_answer","my_chat_member","chat_member"]

'new_chat_members' event sometimes works, sometimes it doesn't

'new_chat_members' event sometimes works, sometimes it doesn't

You too? Is there any dev who is planning to fix this? Do you know a library that works for this? Better not lose more time if it seems so complex to have a fix for node telegram bot .
