Inbound Query Intake Router via Webhook Validation

How it works

1. 1.The webhook node listens for POST requests on the configured path and defers the response to a response node.
2. 2.The Normalize Input node maps the request body to an input field and tags it with a fixed source value.
3. 3.The IF node checks that the input field is not empty to branch the flow.
4. 4.The HTTP Request node POSTs a placeholder parameter to an external URL secured with genericCredentialType authentication.
5. 5.The Respond to Webhook nodes return JSON responses for accepted or invalid requests.

Use cases

• Receiving customer or AI agent queries and routing them to a downstream processing service.
• Acting as a lightweight intake gateway with basic empty-input validation before forwarding.

Requirements

• Activate the workflow so the webhook can receive incoming requests.
• Replace the placeholder URL and body parameter value in the HTTP Request node with real values.
• Configure a generic credential type for the HTTP Request node's authentication.

Setup and testing in n8n

1. Send a POST request with a non-empty body to the webhook path and verify the external service receives it and an accepted response returns.
2. Send a POST request with an empty body and verify an invalid response returns without an outbound request.
