Webhook Request Classifier

Classify an incoming request and return a route, priority, and one-sentence summary. Routes are support, sales, technical, and general. The workflow does not create tickets or contact a team.

Setup

For Open Flow, import the JSON and select a configured Claude Haiku 4.5 model in Classify request. For n8n, select an Anthropic credential in Claude Classifier.

Publish and enable the workflow. Send a JSON POST request with a request field to the webhook URL:

{
  "request": {
    "subject": "Team plan pricing",
    "message": "Can you send a quote for 25 seats?"
  }
}

The request value can contain your own JSON fields or a text string. Both formats use the same wrapper. A successful response has received: true, a route, a priority of high, medium, or low, and a summary.

Malformed model output returns the fallback general / medium with summary Unable to classify. Unknown route and priority labels become general and medium. Model request failures still fail the workflow. Open Flow waits up to 60 seconds for classification; an HTTP timeout does not cancel the run. Review model accuracy for your request types before using the result to make routing decisions.

Changes to the source

• Wait for classification and parsing before sending the HTTP response.
• Serialize request and response JSON safely, including quotes and multiline values.
• Accept the same explicit request wrapper in both formats.
• Parse complete or fenced JSON containing braces inside strings, retain the malformed-output fallback, and normalize unknown labels.
• Remove the source switch with no configured downstream actions.
