AI Telegram Shopping Assistant (n8n) + Paystack + Google Sheets

Turn Telegram shopping into a fully automated checkout flow (AI + Paystack + Google Sheets)

This AI Telegram Shopping Assistant for n8n lets customers shop via your Telegram bot, builds a cart in Google Sheets, generates Paystack payment links, verifies Paystack webhooks with HMAC-SHA512, and confirms successful orders back to Telegram—end to end.

What this workflow does

• Receives customer messages from your Telegram bot (Telegram Trigger).
• Loads user context by extracting chat/user details and retrieving the customer record from the n8n Data Table (ecom_users).
• Uses AWS Bedrock AI (with chat model + memory) to understand the conversation and drive shopping decisions.
• Browses and manages a catalog/cart in Google Sheets via an AI agent that can locate products and update cart rows.
• Generates Paystack checkout links using the Paystack Transaction Initialize API when checkout details are ready.
• Returns AI responses to Telegram so customers see product choices, cart updates, and the payment link.
• Handles Paystack webhooks securely: normalizes the payload, validates authenticity by computing an HMAC-SHA512 hash, and compares it to the x-paystack-signature header.
• Marks orders as paid by verifying the transaction with Paystack, updating the Orders sheet, clearing the matched cart rows, and sending a single payment confirmation message in Telegram.

Use cases

• Launch a Telegram-based storefront without building a full web app.
• Automate cart + checkout using Google Sheets as your product source of truth.
• For SaaS operators: streamline order lifecycle automation with secure Paystack webhook verification.
