Dual-Channel Workflow Error Alerts with WhatsApp & Gmail Reporting

Error Handler: WhatsApp Alert & Gmail Report for Failed Workflows 🎯 What This Template Does / How it Works This template provides a robust, two-step system for handling critical errors in your n8n workflows. It ensures that no workflow failure goes unnoticed, immediately notifying your team via a fast, urgent channel and providing a detailed record via a formal channel.

Instant Trigger & Data Capture: The Error Trigger automatically captures all necessary metadata when an assigned workflow fails, including the error message and ID.

Contact Configuration: The Set node centralizes and prepares recipient contact information (email and phone number) from the error data.

Rapid Response: An urgent notification is sent via WhatsApp for immediate team awareness.

Traceability & Record-Keeping: A short Wait node introduces a delay to prevent notification spam. Following the pause, a comprehensive report is sent via Gmail, ensuring a detailed record of the incident is archived.

This design guarantees high-priority alerts are handled rapidly, while still maintaining essential documentation.

Who’s It For This template is ideal for Ops Teams, Developers, and Automation Engineers who rely on mission-critical n8n workflows (e.g., payment processing, lead capture, data synchronization). If a failure requires immediate human intervention, this system is essential.

How to Set Up Setting up this robust error handler is quick and essential for workflow stability:
