Stripe Charge Success: Send Thank-You Receipts via Gmail

Automatically send a thank-you receipt email when Stripe charges succeed—powered by AI

This n8n workflow listens for Stripe charge.succeeded events, generates a personalized thank-you and receipt message with Anthropic Claude, logs the payment to an n8n Data Table, and emails the customer via Gmail. No manual follow-up needed.

What this workflow does

• Triggers on successful payment: When Stripe reports a successful charge (charge.succeeded), the workflow starts automatically.
• Extracts and normalizes payment details: It pulls and normalizes customer name, email, amount, currency, and payment description from the Stripe event.
• Generates an email with AI: Using Anthropic Claude (via LangChain), it creates:
  • A warm email subject
  • An HTML thank-you + receipt message
  • A one-line internal finance summary
• Logs payment records: It combines AI output with the normalized fields, adds a timestamp, and writes the details and finance summary into an n8n Data Table (e.g., payment_log).
• Sends the email via Gmail: It delivers the generated thank-you/receipt to the customer using a Gmail OAuth2 connection.

Use cases

• SaaS teams sending immediate purchase confirmations after successful Stripe payments.
• E-commerce operators reducing support/admin time by automating receipt emails.
• Finance-adjacent teams maintaining a structured payment_log for reconciliation.

Technical details

• Stripe Trigger: charge.succeeded webhook
• AI generation: Anthropic Claude (Claude Sonnet 4.6) via LangChain agent node (n8nn8n-nodes-langchainagent)
• Data logging: n8n Data Table (e.g., payment_log)
• Email delivery: Gmail node with OAuth2
• Workflow composition includes nodes like set and a sticky note for clarity

Setup reminder: Ensure the Stripe charge includes a valid customer email (e.g., billing_details.email or receipt_email) so Gmail has a proper recipient address.
