This workflow is a powerful reputation management tool designed to proactively filter customer reviews. It helps you encourage positive reviews on Google while capturing negative feedback privately before it impacts your public rating. By using an incentive, it maximizes the number of customers who enter this review funnel, giving you control over your online reputation.

Who’s it for?

This template is essential for any business where Google Reviews are critical: restaurants, clinics, retail stores, local services, and more. If you want to improve your Google star rating by systematically encouraging happy customers to post public reviews and addressing unhappy customers privately, this is the perfect solution.

How it works / What it does

The main job of this workflow is to send customers to a special review landing page. On this page, only reviews of 4 stars or more are directed to your Google Review page, while lower-rated feedback is captured in a private form.

Trigger: A customer scans a QR code (e.g., in your store) and sends a message to your Telegram bot.

Incentivize: The bot checks if the user is new. If so, it sends them a small discount or offer as a thank-you for their business and to encourage them to provide feedback.

Send to Filter Page: After a short delay, the workflow sends a message with a link to your review filtering webpage.

Track & Follow Up: The workflow tracks whether the link has been clicked (updating the status in a Google Sheet). If a user doesn't click the link after 23 hours, an automated reminder is sent to maximize engagement.

How to set up

Crucial Prerequisite: This workflow sends users to a review-filtering webpage. You must have this webpage already built. The page should have logic to send 4+ star reviewers to Google and capture other feedback internally. code

Create a Telegram Bot: Use the BotFather on Telegram to create a bot and get your API token.

Google Sheet: Create a Google Sheet with columns like: ID, First Name, Status, Feedback Message, Timestamp.

Credentials: Add your Google Sheets API and Telegram Bot API credentials to n8n.

Configure Nodes:

In all Google Sheets nodes, select your credential and paste your Sheet ID.

In all Telegram nodes, select your Telegram credential.

In the "Send Review Page Link" and "Send Review Link Reminder" nodes, update the URL to point to your review filtering page.

Create a QR Code: Generate a QR code for your bot's link (e.g., https://t.me/YOUR_BOT_USERNAME) and display it for your customers.

Activate Workflow: Save and activate the workflow.

Requirements

A pre-built review filtering webpage. code

An active n8n instance.

Filter for Positive Google Reviews using Telegram Web Form & Google Sheets

This n8n workflow automates the process of collecting and filtering Google reviews submitted via a Telegram web form, storing them in Google Sheets, and notifying you about positive reviews.

What it does

This workflow streamlines the management of Google reviews by:

Receiving Review Submissions: A Telegram bot acts as a web form, collecting new Google review submissions.
Storing All Reviews: Every submitted review is immediately recorded in a designated Google Sheet for comprehensive record-keeping.
Filtering for Positive Reviews: The workflow checks the submitted review's rating.
Notifying on Positive Reviews: If a review is rated 4 or 5 stars, a notification is sent to a specified Telegram chat.

Prerequisites/Requirements

n8n Account: A running n8n instance (cloud or self-hosted).
Telegram Bot: A Telegram bot token and a chat ID where the bot can send messages.
Google Sheets: A Google Sheet set up to store review data. You will need the Spreadsheet ID and sheet name.
Google Account Credentials: An n8n credential for Google Sheets with appropriate access.

Setup/Usage

Import the Workflow: Import the provided JSON into your n8n instance.
Configure Telegram Trigger:
- Open the "Telegram Trigger" node.
- Select your Telegram Bot API credential. If you don't have one, create a new OAuth2 credential for Telegram.
- Set up the Webhook URL for your bot.
Configure Google Sheets:
- Open the "Google Sheets" node.
- Select your Google Sheets credential. If you don't have one, create a new OAuth2 credential for Google Sheets.
- Enter the Spreadsheet ID and Sheet Name where you want to store the reviews.
- Ensure the column headers in your Google Sheet match the data being sent (e.g., "Rating", "Review Text", "Reviewer Name").
Configure the "If" Node:
- The "If" node is pre-configured to check if the rating field is greater than or equal to 4. You may adjust this condition if your definition of "positive" reviews differs.
Configure Telegram Notification:
- Open the "Telegram" node connected to the "True" branch of the "If" node.
- Select your Telegram Bot API credential.
- Enter the Chat ID where you want to receive notifications for positive reviews.
- Customize the message content to your preference, using expressions to include details from the review (e.g., {{ $json.rating }} stars from {{ $json.reviewerName }}: {{ $json.reviewText }}).
Activate the Workflow: Once all configurations are complete, activate the workflow.

Now, when a user submits a review via your Telegram bot (which acts as a web form), the workflow will automatically process it, store it, and notify you if it's a positive review.

If AI returns non-JSON, keep “Return only a JSON array” as the last line of the prompt and keep jsonOutput enabled. Consider adding validation on parsing.warnings to gate Salesforce writes. For discounts/taxes in OLI: Standard OLI fields don’t support per-line discount amounts directly; model them in UnitPrice or custom fields.
