n8n Google Reviews Workflow: Gmail + Sheets + Telegram

Turn completed jobs into Google Reviews automatically—happy customers get your review link, unhappy customers get private follow-up

This n8n Google Reviews Workflow sends a one-click feedback request by Gmail when a job is marked complete, logs everything in Google Sheets, routes happy customers directly to your Google Business Profile review URL, and alerts you on Telegram when feedback is anything other than “good.”

What this workflow does

• Receives a job-complete webhook: A POST request brings job ID, customer name, email address, and job summary.
• Sends a tracked feedback email: The workflow generates two feedback links (happy/unhappy) and emails the customer an HTML message via Gmail.
• Logs request details to Google Sheets: Appends a row to the “Reviews” sheet with: job_id, requested_at, customer_name, email, job_summary, rating, responded_at.
• Captures the customer’s click: When the customer hits the second webhook, the workflow interprets the response as happy only if explicitly “good”; otherwise it treats it as unhappy.
• Routes outcomes:
  • Happy: Redirects directly to your Google Business Profile review URL.
  • Unhappy: Shows a short thank-you page and sends you a private Telegram alert.
• Updates the original row: Matches on job_id and writes back rating and responded_at.

Use cases

• For SaaS operators collecting reviews after successful onboarding or fulfillment.
• For automation engineers who want measurable review outreach with a feedback trail in Google Sheets.
• For service businesses that want fast reputation wins from happy customers and immediate visibility on unhappy feedback.
