Anybody knows how to send a audio/image using NodeJs to a Telegram bot?

I'm trying to send an audio file to a Telegram bot using node and Telegram Api (sendAudio in this case)

const axios = require('axios');
const FormData = require('form-data');

let payload = new FormData();
payload.append('chat_id', 'ID');
payload.append('audio', './audio.mp3');
// OR  payload.append('photo', fs.createReadStream(`./audio.jpg`));

axios.post(
    'https://api.telegram.org/botMyToken/sendAudio',
    payload,
    {
        headers: {
            'accept': 'application/json',
            'Content-Type': `multipart/form-data;`
        }
    })
    .then(function (response) {
        console.log(response);
    })
    .catch(function (error) {
        console.log(error);
    });

console result is a big obj with:

Error: Request failed with status code 400
at createError (/Users/username/TelegramBot/MyBot/node_modules/axios/lib/core/createError.js:16:15)
at settle (/Users/username/TelegramBot/MyBot/node_modules/axios/lib/core/settle.js:18:12)

at process._tickCallback (internal/process/next_tick.js:114:19) 

headers:
  { Accept: 'application/json, text/plain, */*',
    'Content-Type': 'multipart/form-data;',
    accept: 'application/json',
    'Accept-Language': 'en-US,en;q=0.8',
    'User-Agent': 'axios/0.18.0' },
  method: 'post',
  url: 'https://api.telegram.org/botMyToken/sendAudio',
  data:
   FormData {
    _overheadLength: 210,
    _valueLength: 89,
    _valuesToMeasure: [],
    writable: false,
    readable: true,
    dataSize: 0,
    maxDataSize: 2097152,
    pauseStreams: true,
    _released: true,
    _streams: [],
    _currentStream: null,
    _boundary: '--------------------------432591578870565694802709',
    _events: {},
    _eventsCount: 0 } },

what am I doing wrong? I tried send same file using a simple form, and PHP and it worked, I don't get what's wrong in this code.

I recommend you to use getHeaders() function of FormData module. This solved my problem with sending photo to telegram bot

payload.append('photo', fs.createReadStream(`./audio.jpg`));
... 
headers: payload.getHeaders()
...

You're not sending an audio file, but a string containing a local path to a file, which Telegram of course doesn't have access.

Audio file to send. Pass a file_id as String to send an audio file that exists on the Telegram servers (recommended), pass an HTTP URL as a String for Telegram to get an audio file from the Internet, or upload a new one using multipart/form-data.

The telegram documentation is clear, audio must be:

  • file_id
  • url
  • Post the file using multipart/form-data

You can try this:

payload.append('audio', fs.createReadStream('./audio.mp3'));

I recommend using telegraf which will do all the heavy lifting, and will allow you to use a local file path.

const bot = new Telegraf(process.env.BOT_TOKEN);

bot.on('message', (ctx) => {

  // send file
  ctx.replyWithAudio({ source: './audio.mp3' })

});

bot.startPolling();
