Try n8n Without Installing: Instant Demo Use Cases

Want to run n8n in your browser without installing anything? Open our n8n online editor and start building workflows instantly. Below are step-by-step demo use cases you can clone and run right away.

Demo 1: Webhook → HTTP Request → Set

1. Webhook: Create a Webhook node (method: POST). Copy the test URL.
2. HTTP Request: Add an HTTP node to call a public API (e.g., https://api.github.com/rate_limit).
3. Set: Use a Set node to map response fields (e.g., resources.core.remaining) into a clean JSON.
4. Run: Send a POST to the webhook (with curl or Postman). Observe the run in the Execution panel.

Logs & Debugging

• Open Execution Data to inspect inputs/outputs per node.
• Use Continue On Fail on the HTTP node to capture errors gracefully.
• Attach an Error Trigger to handle exceptions and send alerts.

Demo 2: Webhook → Function → Slack (Mock)

1. Webhook: Receive JSON payload.
2. Function: Transform payload (filter keys, add timestamps).
3. HTTP Request (Mock Slack): POST to a test endpoint (or use Slack API if credentials available).

Error Handling Tips

• Wrap Function logic with try/catch and return structured errors.
• Enable retries on HTTP with a backoff strategy.
• Route failures to an Error Trigger → Webhook/Slack for notification.

Demo 3: Schedule → HTTP → Merge → Set

1. Cron: Run every 5 minutes.
2. HTTP: Fetch two endpoints.
3. Merge: Combine on a key or take most recent.
4. Set: Normalize fields for downstream systems.

Best Practices

• Use Credentials to store API keys securely.
• Annotate nodes and name connections for readability.
• Export JSON to version control; re-import when needed.

Clone Templates

Ready-made templates are available in the playground. Clone a Webhook → HTTP → Set starter, then customize nodes for your API.
