Lead automation based on Webhook with transfer to Google Sheet

An automated lead processing system has been created using n8n.

The workflow receives lead data through a webhook, cleans and normalizes the fields (name, phone, email, status), checks for existing records in Google Sheets, and updates the existing row or adds a new one, preventing duplication.

After processing, the system sends real-time notifications to Telegram, distinguishing between new leads and updated contacts.

This automation helps the business centralize all incoming leads, avoid duplicates, and instantly inform managers.
