💡 Pro Tip — HTTP Request scraping tends to break when sites update their markup. If you’re scraping a major platform, check if ScraperNode covers it — it has maintained scrapers for LinkedIn, Instagram, TikTok, YouTube, and 20+ other platforms that return structured data.

Description

Verify service providers using Telegram and BrowserAct

This workflow transforms your Telegram bot into an intelligent vendor vetting tool. Send the name and location of a service provider (e.g., “Mr. Rooter in Detroit”), and it will automatically scrape Google Maps for reviews, cross-reference the business with OpenCorporates to verify its legal status, and deliver a detailed legitimacy report back to your chat.

Target Audience

Procurement managers, homeowners hiring contractors, and anyone needing to verify the legitimacy of a business quickly.

How it works

  1. Analyze Intent: The workflow receives a message via Telegram. An AI Agent classifies it: is it a casual chat or a verification request?
  2. Extract Details: If a request is detected, the AI extracts the Provider Name and Location from your message.
  3. Scrape Data: BrowserAct executes a background task to scrape Google Maps for reviews/ratings and search OpenCorporates for legal entity filings.
  4. Human Verification (CAPTCHA): If the scraper encounters a CAPTCHA, the workflow pauses and sends a Telegram alert with a link. Once you solve it, the workflow resumes automatically.
  5. Verify & Report: A second AI Agent analyzes the gathered data. It compares the Google listing with the corporate registry to determine if the business is “Verified” (matched), “Unverified” (local only), or “Not Found.”
  6. Deliver: The bot sends a formatted HTML report with the verdict, ratings, and active locations to your Telegram chat.

How to set up

  1. Configure Credentials: Connect your Telegram, BrowserAct, and Google Gemini accounts in n8n.
  2. Prepare BrowserAct: Ensure the Vendor Vetting and verification bot template is saved in your BrowserAct account.
  3. Configure Telegram: Ensure your bot is created via BotFather and the API token is added to the Telegram credentials.
  4. Activate: Turn on the workflow.
  5. Test: Send a message like “Is Acme Plumbing in Chicago legit?” to your bot to start the verification process.

Requirements

How to customize the workflow

  1. Add More registries: Update the BrowserAct template to search other databases like BBB (Better Business Bureau) or Yelp for broader verification.
  2. Change Output Format: Modify the system prompt in the Verify the provide agent to output a simple “Pass/Fail” score instead of a detailed report.
  3. Save Reports: Add a Google Sheets or Notion node at the end to log every verification request and its result for future reference.
