Urgent Vaccination Alert Automation

Real-time trip inquiry triage system that classifies urgency, sends high-priority Discord alerts for urgent vaccination needs, retries failed urgent posts after 90 seconds, and routes standard inquiries to a separate channel.

Urgent Vaccination Alert Automation workflow

Context

Trip inquiry teams needed a reliable way to identify urgent vaccination-related travel questions and ensure critical alerts were never missed, even when Discord delivery temporarily failed.

Approach

Built two connected n8n workflows that parse and classify incoming trip inquiries, route urgent cases to a high-priority Discord channel with an automatic 90-second retry on post failure, send non-urgent inquiries to a standard channel, and monitor the entire system with a dedicated error handler.

Architecture

  1. Webhook POST (trip inquiry)
  2. Parse + urgency classify
  3. Non-urgent: Discord standard alert
