WhatsApp & Telegram Digital Delivery via Stripe + n8n

Capture WhatsApp/Telegram leads, take payment with Stripe, then auto-send your PDF—instantly with n8n

This n8n workflow listens for incoming messages from WhatsApp and Telegram, logs each lead in Google Sheets, sends a Stripe Payment Link, and—after successful checkout—delivers a Google Drive PDF download link back on the same channel.

What this workflow does

• Receives customer messages via webhooks from WhatsApp Business Cloud API and Telegram.
• Extracts sender details (identifier / chat ID or phone) and message text.
• Logs the lead in Google Sheets including channel (WhatsApp/Telegram), chat ID/phone, message, and timestamp.
• Sends a Stripe Payment Link back to the customer on WhatsApp or Telegram and immediately responds to the webhook request.
• Waits for payment confirmation by handling Stripe webhook events for checkout.session.completed.
• Finds the matching lead by looking up the payer’s phone number in Google Sheets to determine whether they originated from Telegram or WhatsApp.
• Delivers content automatically by sending a Google Drive direct-download PDF link on the matching channel; if no lead is found, it sends a fallback WhatsApp message.

Use cases

• Sell a digital product (PDF download) directly from WhatsApp and Telegram with Stripe.
• Generate and track inbound leads in Google Sheets while automating payment and delivery.
• Implement a lightweight conversational checkout flow for SaaS operators and automation engineers using n8n automation.
