Discord Bot Webhook Tester
Fire test messages at any Discord webhook URL straight from your browser — content, username/avatar override, TTS, embeds (paste JSON or build with our embed-builder), wait=true toggle. Live response panel with status code, body, and timing. Copyable curl / fetch / Python requests snippets matching the exact payload. Validates webhook URL format, content length (2000 max), embed count (10 max). Language-agnostic — works for any stack that POSTs JSON.
Server Settings → Integrations → Webhooks → New Webhook → Copy Webhook URL. Stays in your browser; we never log it.

"content": "Hello from xtools!"
}'FAQ
Why did I get 204 No Content with no body?
That's success. Discord returns 204 when the message was accepted but you didn't ask for the resulting message object. Toggle ?wait=true above to get a 200 with the message JSON instead.
What's the rate limit?
5 requests per 2 seconds per webhook (channel). Bots that need higher throughput should use the bot's /channels/{id}/messages endpoint, not webhooks.
Why does my embed-only send fail with 400?
Either your embeds JSON is invalid (this tool will flag that above) or you exceeded the 10-embed limit. Embeds also have field-level limits — title 256, description 4096, fields 25, total 6000 chars across all embed fields per message.
Can this upload files / images?
Not in this tool. File attachments require multipart/form-data with a payload_json part — not a JSON-only POST. For testing file uploads, use the curl snippet as a starting point and add -F "files[0]=@image.png".
My webhook URL leaked — what now?
Anyone with the URL can post as that webhook. Delete it in Server Settings → Integrations → Webhooks and create a new one. Webhook URLs are credentials.
Does this support threads?
Not directly via the form. Append ?thread_id=<id> to the webhook URL to send into a specific thread, or set thread_name in the JSON for forum/media channels.
