Webhook router handling ping and process actions

How it works

1. 1.Webhook node accepts POST on path template/scalable-orchestrator with response deferred to a response node
2. 2.Parse Input reads action from the body defaulting to ping, and sets payload with a default object {id:123, text:"hello"}
3. 3.Switch node routes to the ping or process output based on the action value, with non-matches ignored
4. 4.The ping branch builds {ok:true, message:"pong"} and passes it straight to the response node
5. 5.The process branch POSTs the payload as JSON to https://httpbin.org/post with retryOnFail and maxRetries set to 2, then shapes the result into {ok, data, source:"serviceA"}
6. 6.Respond to Webhook returns the final JSON object to the caller

Use cases

• Lightweight API health-check endpoint via the ping action before sending real data
• Single entry point that forwards request payloads to an external service and returns its result synchronously
• Starter template to extend routing with additional actions by adding Switch rules

Requirements

• Workflow must be activated in n8n for the production webhook URL to work (currently inactive)
• No credentials needed in the current setup since the default httpbin.org service is public; add appropriate credentials when replacing it with a real API
• Network access from the n8n instance to the target external service
• Requests must be JSON with an action field in the body to trigger the correct branch

Setup and testing in n8n

1. Activate the workflow and curl -X POST to /webhook/template/scalable-orchestrator with {"action":"ping"} and verify the pong reply
2. Send {"action":"process","payload":{"id":1,"text":"hello"}} and verify the returned data includes source:"serviceA"
3. Send an unknown action such as "test" and expect no response since the fallback output is disabled
4. Replace the httpbin URL with a controllable endpoint and re-send to observe retry behavior on service failure
