Discord Webhook Builder

Webhook payloads are simple JSON that is nonetheless easy to get subtly wrong, and Discord's error for a malformed one tells you very little. Build it against a preview, then send it from your own machine.

Optional. Leave blank to use the webhook’s own name.

Shown above the embed. This is the part that can mention people.

The payload

{
  "username": "Server Status",
  "embeds": [
    {
      "color": 5763719,
      "title": "Server is back online",
      "description": "Scheduled restart complete. Everything is running normally.",
      "footer": {
        "text": "spawnly.net"
      },
      "fields": [
        {
          "name": "Players",
          "value": "12 / 100",
          "inline": true
        }
      ],
      "timestamp": "2026-01-01T00:00:00.000Z"
    }
  ]
}

Send it from your own machine

The webhook URL is a credential — anyone holding it can post to that channel. It stays in your environment and never comes near this page.

curl -H "Content-Type: application/json" \
  -d '{
  "username": "Server Status",
  "embeds": [
    {
      "color": 5763719,
      "title": "Server is back online",
      "description": "Scheduled restart complete. Everything is running normally.",
      "footer": {
        "text": "spawnly.net"
      },
      "fields": [
        {
          "name": "Players",
          "value": "12 / 100",
          "inline": true
        }
      ],
      "timestamp": "2026-01-01T00:00:00.000Z"
    }
  ]
}' \
  "$DISCORD_WEBHOOK_URL"

How this works

A webhook message is either plain content, an embed, or both — Discord rejects a payload with neither. The embed is where the structure is: a colour as a decimal integer rather than a hex string, an optional title and description, and up to ten fields that can sit inline beside each other or on their own lines. The builder emits the payload and a curl command that reads the webhook URL from your environment.

What people get wrong

This page will not send anything, and that is deliberate. A form that accepts a webhook URL and posts to it is an anonymous relay for posting into other people's Discord servers, which is a spam tool with a friendly interface. The generated curl reads the URL from an environment variable for the same reason it matters on your side: a webhook URL is a credential, and anyone who has it can post to that channel until you rotate it.
