## Tools
- api_test_webhook - Use this when you need to test a webhook endpoint by sending a request with custom headers, body, and method. Returns full response data in JSON.

Returns: 1. statusCode 2. responseBody (parsed JSON or text) 3. responseHeaders (key-value map) 4. latency in ms 5. tlsInfo (protocol, cipher) 6. method used 7. requestSize and responseSize in bytes.

Example output: {"url":"https://hooks.example.com/callback","method":"POST","statusCode":200,"responseBody":{"received":true},"latency":142,"tlsInfo":{"protocol":"TLSv1.3","cipher":"AES-256-GCM"},"requestSize":256,"responseSize":48}

Use this FOR testing webhook integrations, debugging API callbacks, validating endpoint availability, and measuring webhook response times.
