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

  • BrowserAct account with the Vendor Vetting and verification bot template.
  • Telegram account (Bot Token).
  • Google Gemini account.

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.

4. Reproducing the Workflow from Scratch

  1. 1. Download the workflow JSON

    Use the JSON export at /data/workflows/12432/12432.json as the source template for this automation.

  2. 2. Import the template into n8n

    Open n8n, import the downloaded JSON, and review each node before activating the workflow.

  3. 3. Configure credentials and variables

    Replace placeholder credentials, API keys, webhook URLs, account IDs, and environment-specific values with your own settings.

  4. 4. Test with sample data

    Run the workflow manually or in a staging workspace, inspect node output, and confirm downstream systems receive the expected data.

  5. 5. Activate and monitor

    Enable the workflow only after testing, then monitor executions, errors, and rate limits during the first production runs.

5. General Notes & Resources

Review imported nodes carefully before activation. This catalog entry is intended to help you inspect the workflow structure, understand required services, and find related templates faster.

Node names, credentials, schedules, webhook paths, and external service limits may need adjustment for your workspace.
