Stripe Webhook to Email Alerts (Checkout Completed) in n8n

Get instant email alerts when a Stripe checkout completes—fully automated in n8n

This n8n workflow listens for Stripe webhook events and, when a checkout.session.completed occurs, automatically sends a plain-text email alert with the event type, customer email, and total amount via SMTP.

What this workflow does

• Receives a POST request at the workflow’s /stripe-payment webhook endpoint containing a Stripe event payload.
• Checks the event type and proceeds only if it equals checkout.session.completed.
• Sends an email alert to your configured recipient using SMTP, including:
  • Event type
  • Customer email
  • Total amount

Use cases

• SaaS operations monitoring: notify your team immediately when customers finish checkout.
• Payment reconciliation support: receive quick, human-readable email confirmations for completed Stripe checkouts.
• Automation engineers: a simple baseline workflow to validate Stripe webhook handling and email notifications in n8n.

Technical details

• Triggers/endpoint: n8n Webhook node that accepts Stripe POST requests at /stripe-payment.
• Routing logic: if node to verify event type == checkout.session.completed.
• Email delivery: email send node using SMTP with your configured credential.
• Message format: plain-text email containing the event type, customer email, and total amount.

Setup checklist

• Configure Stripe to send webhook events to this workflow’s webhook URL and include checkout.session.completed.
• In n8n, add an SMTP credential and confirm the From and To email addresses used for the alert message.
