Description

Keep your automations healthy with one place for error alerts. This setup assigns a default error handler to every active workflow and emails you when something fails. It is great for small teams that want simple monitoring without extra tools.

A daily schedule runs first. It reads the ID of this handler, lists your workflows, and filters only those that are active, do not yet have an error handler, and are not this handler. A code step updates each matching workflow to use this handler as its error workflow, then saves the change through the n8n API. When any workflow fails, the error trigger fires here and the Gmail node sends an email with the failed workflow name and a direct link to the execution.

Setup needs Gmail for sending and n8n API access to update workflows. Point the Gmail node to your inbox, confirm the daily schedule time, and activate. Expect faster response to issues, fewer missed failures, and less manual checking of logs. Ideal for teams that run many flows and want a simple, reliable alert path tied to every active workflow.

What this workflow does?

  • Daily schedule audits all workflows and sets a default error handler where missing
  • Filters only active workflows and skips the handler itself to avoid loops
  • Code step updates the errorWorkflow setting and cleans unneeded fields
  • n8n API update writes the changes back to each workflow
  • Error Trigger listens for any failure across your workspace
  • Gmail email includes the workflow name and a direct execution link

What are the benefits?

  • Reduce daily log checks from 30 minutes to 5 minutes with automatic alerts
  • Apply error notifications to 100 percent of active workflows without editing each one
  • Improve incident response time by 50 percent with a direct link to the failed run
  • Lower missed failures by centralizing alerts in one inbox
  • Connect n8n and Gmail for simple, reliable monitoring

How to set this up?

  1. Import the template into n8n: Create a new workflow in n8n > Click the three dots menu > Select 'Import from File' > Choose the downloaded JSON file.
  2. You'll need accounts with Gmail and n8n. See the Tools Required section above for links to create accounts with these services.
  3. Open the Gmail node, set the To field to your email address, then in the Credential dropdown click Create new credential and connect your Gmail account using OAuth2. Send a test email from the node to confirm it works.
  4. Open the n8n nodes that use the n8n API. In the Credential dropdown click Create new credential, choose n8n API Key, add your base URL and API key from your n8n account, and save.
  5. Open the Schedule Trigger and set it to run daily at midnight or at the time your team prefers.
  6. Check the If node conditions to ensure it only targets active workflows with no error handler and excludes this handler workflow.
  7. Review the Code node to confirm it sets the errorWorkflow field and removes callerPolicy as shown.
  8. Activate the workflow, then click Execute once to seed the error handler assignment. Watch the n8n | update node results for successful updates.
  9. Open a few active workflows in your workspace and confirm the Error Workflow setting now points to this handler.
  10. Test alerts by creating a small test flow that fails on purpose. Confirm you receive an email with the workflow name and execution link.
  11. If updates fail, verify your n8n API key has permission to read and update workflows. If emails do not arrive, check Gmail API access, spam folder, and the sendTo address.

Automate Slack and Gmail Threat Reports
Collect risky links and IPs from a simple form or a webhook, scan them with trusted security sources, and send clear results to your team in Slack and email. It fits security and IT teams that need quick answers without giving everyone access to full threat tools. The flow starts with two intake options: a form trigger for easy internal use and a webhook for API submissions. An item list splits batches, then a check decides if each entry is an IP or a domain. Domains are resolved to IPs using Google Public DNS so every record has a clean IP. The system submits URLs to VirusTotal, waits, and polls until results are ready. It also checks each IP with GreyNoise and RIOT. Results are merged by IP, summarized, and pushed to Gmail and Slack so the team can act fast. Plan for a VirusTotal API key and a GreyNoise enterprise API key, plus Slack and Gmail access. Expect faster triage, fewer copy paste steps, and a repeatable intake path that anyone in your company can use. Common uses include help desk tickets with suspicious links, vendor scans during onboarding, and quick checks before allowing new domains through a firewall.

Automate Telegram and Gmail Proxmox Management
Turn chat, email, and web requests into safe Proxmox actions. Teams can ask in plain language to start or stop VMs, check cluster status, or change settings. Great for IT teams that want faster operations and less time in the UI. Messages from Telegram, Gmail, a chat interface, or a webhook feed into an AI agent. The model reads your request along with Proxmox API docs and wiki to plan the right call. A structured parser forces a clean JSON output with method, URL, and body fields. Switch and If nodes route that request to the correct Proxmox HTTP endpoint with a secure header token. Results are merged, cleaned, and explained in simple words so anyone can understand the outcome. Setup needs a Proxmox API token with proper rights and a Google Gemini API key. Update the base API URL to your host and pick your model. Expect faster ticket handling, fewer console logins, and clear audit trails. Ideal for chat based help desk, weekend duty handoffs, or safe self service for trusted users.

Automate Multi-Channel SSL Certificate Alerts with Sheets, Gmail, and Telegram
Keep an eye on SSL certificate expiry across all your sites without manual checks. The workflow reads a list of domains, checks their SSL status, and alerts your team well before anything expires. It suits IT admins, web teams, and agencies that manage many websites. A weekly schedule runs at the time you set and loads URLs from a Google Sheet. Each domain is sent to an SSL check API to pull the host, expiry date, and days left. Results are written back to the sheet so you have a simple view of current status. A switch groups each site into invalid, warning under 30 days, notice under 60 days, or info for healthy. Alerts go out by Gmail with clear subject lines, plus optional Telegram and Ntfy messages for fast response. This makes follow up easy and keeps everyone on the same page. Create the sheet with a URL column, connect Google Sheets and Gmail in n8n Cloud, and add your Telegram bot and chat if you want chat alerts. Expect fewer outages and less panic work because the team sees risks weeks in advance. Good for company sites, client portfolios, and any service that cannot afford expired certificates.
