Shopify Order Confirmation Automation with Claude Sonnet + Gmail

Send instant, AI-personalized Shopify order confirmations—plus a relevant upsell

This n8n workflow automatically detects new Shopify orders, uses Claude Sonnet (Anthropic) to generate a personalized HTML order confirmation with one relevant upsell, then emails the customer via Gmail and logs the details to an n8n Data Table.

What this workflow does

• Triggers on new Shopify orders when Shopify creates an order.
• Extracts and normalizes key order fields such as order number, customer name, email, total, and line items.
• Calls Anthropic Claude Sonnet with the normalized order details to generate a JSON response including:
  • an email subject
  • an HTML confirmation message
  • an internal upsell note
• Combines AI output with order data and adds a timestamp for logging.
• Logs order details and upsell note to an n8n Data Table (e.g., order_log).
• Sends the generated confirmation email to the customer using Gmail.

Use cases

• Reduce support tickets by sending polished, immediate Shopify order confirmations.
• Increase post-purchase revenue with a single, relevant upsell suggestion generated per order.
• Maintain operational visibility by recording order_number, items, and upsell_note for review and reporting.

Technical details (n8n)

• Shopify Trigger for orders/create
• Set node for field mapping and normalization
• n8n-nodes-langchainagent (Anthropic Claude Sonnet) to generate email subject + HTML + JSON upsell note
• Gmail node using OAuth2 to send customer confirmations
• Data Table logging (fields: order_number, customer_name, email, total, items, upsell_note, logged_at)
• (Optional) Sticky Note for workflow readability

Setup essentials: connect Shopify access token credentials, add an Anthropic credential for Claude Sonnet, provide a Gmail OAuth2 credential and sender mailbox, and ensure the n8n Data Table (like order_log) exists.
