How can I send a message to a discord webhook through a browser console – Javascript

I’m trying to make code that can send a message to a discord webhook through a browser console but I can’t get it to work

I tried this, as well as some reddit threads and reading the docs

Edit: I also tried using a referrer and origin header with no success

fetch('https://discord.com/api/webhooks/WEBHOOK_ID/WEBHOOK_TOKEN', {
  method: 'POST',
  headers: {
    'Content-Type': 'application/json'
  },
  body: JSON.stringify({
    content: 'hello world'
  })
});

I’m getting a POST 400 error but i cant for the life of me figure out why
(Yes im using an actual URL when i try the code)

POST https://discord.com/api/webhooks/[ID/TOKEN] 400
(anonymous) @ 00a5b07b3b8bf783d65a.js:153
(anonymous) @ VM234:1

    Discord doesn't allow webhook requests from their own site for security reasons My best guess is that they dont want people to be able to send discord cookies with a webhook

    You can always check this website for help

    https://discohook.org/

    For example I tried one and checked the network request that was fired upon the webhook send was something like this.

    So maybe embeds:null and attachments:[] is required in the body

    fetch("https://discord.com/api/v10/webhooks/id/token", {
  "headers": {
    "accept": "application/json",
    "accept-language": "en",
    "content-type": "application/json",
    "sec-ch-ua": ""Google Chrome";v="111", "Not(A:Brand";v="8", "Chromium";v="111"",
    "sec-ch-ua-mobile": "?0",
    "sec-ch-ua-platform": ""Linux"",
    "sec-fetch-dest": "empty",
    "sec-fetch-mode": "cors",
    "sec-fetch-site": "cross-site",
    "Referrer-Policy": "strict-origin"
  },
  "body": "{"content":"This is a webhook message from the browser","embeds":null,"attachments":[]}",
  "method": "POST"
});
