Handling Stripe payments manually is fine for a side project — until it's not. Whether you're running a SaaS product or managing client projects, automation can save hours of repetitive work.

In this guide, we’ll walk through setting up a Stripe automation workflow in n8n that:

  • Listens for successful payments in Stripe
  • Sends a thank-you email to your customer
  • Stores the data in Google Sheets or Airtable for tracking

Let’s dive in.

🧰 What You’ll Need

  • A free n8n account or self-hosted instance
  • A Stripe account
  • A Gmail account (or any SMTP)
  • Optional: Google Sheets/Airtable account for logging

🔌 Step 1: Trigger on Stripe Payment Success

  1. In your n8n workflow, add a Stripe Trigger node.
  2. Set the event to checkout.session.completed or invoice.payment_succeeded depending on your use case.
  3. Connect your Stripe account using the secret key.
  4. Configure the webhook URL in your Stripe dashboard (this happens automatically for n8n cloud).

At this point, your workflow is listening for successful payments.

✉️ Step 2: Send a Confirmation Email

  1. Add a Gmail (or SMTP) node.
  2. Set To to {{$json["customer_email"]}} from the Stripe event.
  3. Craft a subject like: Thanks for your payment!
  4. Include dynamic fields like customer name or payment amount in the email body.

Here’s a quick example:

htmlCopyEditHi {{ $json["customer_name"] || "there" }}, Thanks for your recent payment of ${{ $json["amount_total"] / 100 }}. We truly appreciate your support! - Shourav

📊 Step 3 (Optional): Log to Google Sheets or Airtable

If you want to maintain a payment record:

  • Add a Google Sheets or Airtable node.
  • Map the fields like: name, email, amount, and timestamp.
  • You’ll now have a real-time payment dashboard.

🧠 Pro Tip: Add Fail-Safes

  • Use a Set node to validate required data.
  • Add a Slack or Telegram node to notify your internal team when something fails.

Test Your Flow

Use Stripe’s test mode to simulate a payment and watch your n8n workflow execute. Confirm the email is sent, and data is logged.

💡 Real-World Use Cases

  • SaaS billing: Automate new user welcome emails after payment
  • Agencies: Notify your team when a client pays an invoice
  • Course creators: Unlock access or send PDF content automatically

🎯 Why This Matters

Manual payment handling creates friction and leads to missed follow-ups. With this automation:

  • Your Stripe billing becomes hands-free
  • Customers feel appreciated instantly
  • You stay organized without lifting a finger

🚀 Next Steps

  • Add retry logic for failed email attempts
  • Integrate with a CRM or Notion database
  • Build a customer portal with n8n + Supabase
