DingTalk Robot Tester
Paste your DingTalk custom robot webhook URL and optional secret, choose a message type (text, markdown, link, actionCard), compose the content and send a test message directly from your browser. The tool also generates the exact cURL command with the correct HMAC-SHA256 signature so you can run it locally if the browser blocks the request due to CORS.

If CORS blocks the browser request, copy the cURL command and run it locally.
Frequently asked questions
Is my webhook secret uploaded to this site?
No. The request is sent directly from your browser to the DingTalk API server. The secret only stays in the current page and is used for local HMAC-SHA256 signature calculation.
Why does the browser sometimes block the request?
DingTalk API does not allow cross-origin (CORS) calls from a browser. If that happens, copy the generated cURL command and run it in your terminal.
