Automatically track competitor prices and sync to Google Sheets, Telegram

This automation simplifies the process of monitoring competitor product prices, alerting on significant changes, and logging historical price data.

It fetches a product list from a Google Sheet, scrapes each product page for the current price, compares against the last known price, and sends a Telegram alert if a price change is detected. The updated prices are then logged to a separate tracking sheet. This workflow is designed to help businesses stay informed about their competitors' pricing strategies and make data-driven pricing decisions.

What this template does

  • Fetches a list of products from a Google Sheet to monitor
  • Scrapes the current price from each competitor's product page
  • Compares the scraped price to the last known price
  • Sends a Telegram alert when a significant price change is detected

How it works

1
Trigger

Fetch Product List from Sheet

The workflow starts by reading the product URLs and last known prices from a Google Sheet. This sheet contains the list of competitor products to monitor.

2
Action

Load Product Page HTML

For each product in the list, the workflow uses a headless browser to fetch the current HTML content of the corresponding product page.

3
Logic

Extract Current Price

The workflow then parses the HTML to extract the current price of the product, using code to identify and extract the relevant price information.

4
Logic

Compute Price Change

The current price is compared against the last known price from the Google Sheet, and the price change is calculated.

5
Action

Log Price History

The price change data is then appended to a separate tracking sheet in Google Sheets, creating a historical record of the product prices.

6
Action

Update Last Price

The new price is written back to the master product list in the Google Sheet, updating the last known price for each product.

7
Action

Send Price Alert

If a significant price change is detected, the workflow sends a notification to a configured Telegram chat, alerting the business about the pricing update.

8
Trigger

Schedule Trigger

The entire workflow is scheduled to run daily at 8 AM server time, ensuring the product prices are monitored and updated regularly.

Setup guide

1

Add Google Sheets credential

Add your Google Sheets OAuth2 credential in the Latenode Credentials panel. This will allow the workflow to securely access your Google Sheets.

2

Configure Google Sheets connection

In the Google Sheets node settings, enter the ID of the Google Sheet you want to use, and specify the tab names for the 'product_data' and 'price_tracking' sheets.

3

Set up Telegram connection

Add your Telegram bot token and chat ID in the Latenode Credentials panel. This will enable the workflow to send price change alerts to your Telegram channel.

4

Customize CSS selector for price extraction

In the Headless Browser node settings, update the CSS selector used to extract the current product price from the HTML. This may need to be adjusted based on the structure of the competitor websites you are scraping.

5

Review and adjust workflow settings

Review the other node settings, such as the batch size, delay between requests, and price change thresholds, to ensure the workflow fits your specific requirements.
