n8n Lead Validation Webhook + Telegram Priority Alerts

Instant lead validation + Telegram priority alerts—built with n8n

Turn website enquiries into qualified leads automatically. This n8n workflow accepts form submissions via a webhook, validates and scores them with rule-based logic (English/Spanish), returns a localized browser response, and then sends high-signal lead alerts to your Telegram chat with a Hot/Warm/Standard priority label.

What this workflow does

• Receives enquiries: Accepts a POST request from your website form through an n8n webhook endpoint.
• Normalizes and protects: Normalizes incoming fields, checks a honeypot to reduce spam, validates the email, and enforces a minimum message length.
• Detects language: Detects whether the submission is English or Spanish.
• Scores lead quality: Calculates a 0–100 priority score using rule-based logic.
• Responds with localization: Returns a JSON message to the browser with an HTTP status of 200 for valid leads or 400 for rejected submissions—written in the detected language.
• Sends Telegram priority alerts: For valid submissions, formats a lead alert including the score and a Hot/Warm/Standard label and sends it to your specified Telegram chat.

Use cases

• Agencies or SaaS operators that need to filter low-quality enquiries before they hit the inbox.
• Teams routing inbound leads to a dedicated channel for faster follow-up via Telegram.
• Multilingual websites that require English/Spanish validation responses to users.
