Q:

How to Post to a Discord Webhook with Discord.js (code 400 Bad Request)?

I'm trying to access a discord Webhook using Nodejs for simple messages (for now). 
I have looked at several attempts here and at other places, but didn't quite understand them or was able to replicate them myself. Reading through the docs and searching online I found node-fetch which in my eyes should work fine in principle, while seemingly simpler.
const fetch = require('node-fetch');
          var webhook = {
            "id":"my webhook id",
            "token":"my webhook token"
          };
          var URL = `https://discordapp.com/api/webhooks/${webhook.id}/${webhook.token}`;

          fetch(URL, {
            "method":"POST",
            "payload": JSON.stringify({
              "content":"test"
            })
          })
            .then(res=> console.log(res));

The only output I ever get is a Response Object with status code 400. The only time I do get something else is when I remove the method, then I get code 200 which doesn't help much...
Is my payload somehow completely wrong or did I make a mistake with the URL or fetch syntax?

A:

Instead of making your own POST request, you can use the WebhookClient built into Discord.js like so...
const id = '';
const token = '';

const webhook = new Discord.WebhookClient(id, token);

webhook.send('Hello world.')
  .catch(console.error);
