SIGNL4: Send and Resolve Alerts with POST Requests

This workflow automates incident alerting via SIGNL4, replacing manual phone calls, emails, or Slack pings that disrupt teams during emergencies. The Webhook Trigger receives POST requests with action (send/resolve) and message, the Input Validation If node checks for valid fields, the Check Action Type If node routes to SIGNL4 Send Alert or Resolve Alert nodes, the Check Send/Resolve Success If nodes verify outcomes, and Success/Error Response Respond to Webhook nodes return JSON status. It helps IT ops in small-mid businesses (10-50 staff) managing 50+ alerts weekly, enabling instant mobile notifications for critical issues like server downtime without constant monitoring, reducing response times from minutes to seconds and minimizing outages that cost $5K/hour.\n\nThis workflow saves 4-6 hours weekly on 50 alerts, cutting MTTR by 70%. Use cases include on-call rotations for SaaS monitoring, emergency escalations for e-commerce. Suitable for small teams. Requires SIGNL4 ($10/month starter); n8n (free self-hosted or $20/month cloud). Scalable to 200 alerts/day with SIGNL4 Pro.\n\nInstall n8n via n8n.io or cloud.n8n.io. Get SIGNL4 token at signl4.com (create team, generate API token). Set SIGNL4_TOKEN env var. Import JSON, configure Webhook POST 'signl4-alert.' Update SIGNL4 nodes with API type/token. Webhook URL: https://your-n8n-instance/webhook/signl4-alert.\n\nTest with Postman: {action: 'send', message: 'Server down'}. Verify SIGNL4 alert. Errors: Invalid token (401, regenerate), missing action (400). Activate webhook. Monitor dashboard weekly.
