Not getting an update with callback_query when user presses an inline button (Telegram webhook)

Question

Using node-telegram-bot-api. I have a Webhook that works properly - i get updates when messages are sent, but no update is sent when the user presses a button in an inline keyboard.

class BotController {
 async handleUpdate(req, res, next){
 console.log(req.body);
 if (req.body.message.text === "/getTypes"){
 sendTypesKeyboard(req.body.message.chat.id);
 }
 return res.json({message: "update handled"});
 } 
}
const sendTypesKeyboard = async (chatId) => {
 const types = await typeDbHandler.getAll();
 const options = {
 reply_markup: JSON.stringify({
 inline_keyboard: types.map((type) => 
 [{"text": type.name, "callback_data": type.id}]
 )
 })
 }
 bot.sendMessage(chatId, "Choose the type", options);
}

I tried to use polling and handle a callback_query event, but it didn't work either

const TelegramApi = require('node-telegram-bot-api');
const BOT_TOKEN = process.env.BOT_TOKEN;
const bot = new TelegramApi(BOT_TOKEN, {polling: true});
// bot.setWebHook(`${process.env.URL}/bot`);
bot.on('callback_query', (query) => {
 console.log(query);
})
bot.on('message', msg => {
 console.log(msg);
})
module.exports = bot;

Again, updates with messages are recieved, but callback_query is never fired

Answer 1

I'm wondering if you're even getting the callback_query updates. Can you please update the LongPolling example with the following code:

const bot = new TelegramBot("TOKEN", {
 polling: {
 params: {
 allowed_updates: [
 "message", "callback_query", // list any other ...
 ]
 }
 }
});

Basically what changed is, we know explicitly request callback_query updates to be sent from Telegram Bot API server.

And you can also do the same while calling the /setWebhook call. Specify the allowed_updates as query parameter or in the JSON body.

Example:

https://api.telegram.org/bot<TOKEN>/setWebhook?url=<YOUR_URL>&allowed_updates=["message", "callback_query"]

Make sure to replace with your actual Bot Token, and <YOUR_URL> with your webhook URL. Also, feel free to add any further update types you want to listen to the allowed_updates parameter list.

Hope this helps.
