Never miss a failed workflow again. This error notification setup watches your n8n workflows around the clock and pings you on Telegram and Gmail the moment something breaks, with optional Discord, Slack, and WhatsApp support.

Last updated: September 2026.

Why Use Error Notification Workflow?

  • Immediate Awareness: Get instant alerts when workflows fail, so broken automations never go unnoticed.
  • Multi-Channel Flexibility: Notify your team via Telegram, Gmail, and optionally Slack, Discord, or WhatsApp.
  • Detailed Context: Every alert carries the error message, node name, time, and execution link, so you can fix things fast.
  • Easy Integration: Built with native n8n nodes and customizable code. No complex setup.
  • Open Source & Free: Use and adapt it at no cost. Professional error monitoring for everyone.

Who Is This For?

  • n8n Workflow Developers: Spot and respond to automation issues in development or production.
  • Operations Teams: Maintain uptime and troubleshoot errors across multiple workflows.
  • Small to Medium Businesses: Get professional error alerting without expensive monitoring tools.
  • Automation Enthusiasts: Make your automations reliable with real-time failure notifications.

What Problem Does It Solve?

This workflow embeds error detection and notification directly inside your n8n instance. It catches errors as they happen, compiles the context that matters, and delivers it instantly to your preferred messaging platforms. You respond to issues faster and stop guessing what went wrong.

What This Workflow Does

  • Trigger: Listens for any error in your n8n workflows using the n8n Error Trigger node.
  • Format: Runs a Code node that builds a detailed error message with workflow name, error node, description, timestamp, and execution URL.
  • Notify: Sends the formatted alert to Telegram and Gmail by default, plus optionally Discord, Slack, and WhatsApp (disabled by default).
  • Deliver: Rich, parsed HTML-formatted messages so errors are readable and actionable at a glance.

  1. Import the provided .json file into your n8n instance (Cloud or self-hosted).

  2. Set up credentials:

    • Telegram API credentials for Telegram notifications
    • (Optional) Discord Webhook URL credential for Discord notifications
    • (Optional) Slack Webhook credential for Slack notifications
    • (Optional) WhatsApp connection credentials (if enabled)

  3. Customize the Code node if needed to adjust the error message format or target chat IDs.
