Parse and Classify Event

Build Sub-Workflows

Add Error Handling

Test and Deploy

1
Create Webhook Trigger

Add a Webhook node. Set method to POST. Copy the webhook URL. This URL will receive all events from your external apps. Configure a response to return 200 OK immediately.
2
Parse and Classify Event

Add a Code node to parse the incoming JSON. Extract event_type from the payload. Use a Switch node to route based on event_type: payment_received, form_submitted, issue_opened, etc.
3
Build Sub-Workflows

For each event type, create a sub-workflow: payment_received updates CRM + sends receipt, form_submitted adds to spreadsheet + sends welcome email, issue_opened creates Slack alert + assigns in project tool.
4
Add Error Handling

Add an Error Trigger node that catches failures and sends a Slack/Discord notification with the error details. Set retry logic: 3 retries with exponential backoff for API failures.
5
Test and Deploy

Send test webhooks using curl or Postman for each event type. Verify routing works correctly. Configure your external apps to send webhooks to this n8n endpoint. Monitor the execution log daily for the first week.
