Webhook-Triggered Automation Hub with n8n

This n8n workflow creates a webhook endpoint that receives events from your apps (Stripe, Typeform, GitHub, etc.), classifies the event type, and routes it to the appropriate sub-workflow. Centralizes all your automations in one place.

Step-by-Step Guide

1. 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. 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. 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. 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. 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.
