How to Build a Stripe Failed-Payment Alert with n8n (Free Template)

Description and use

A minimal 3‑node n8n workflow that instantly emails you when a Stripe payment fails, eliminating manual checks.

Problem

Subscription businesses lose MRR when payments fail, but Stripe only shows failures in its dashboard, requiring manual checks or support tickets.

Outcome

A minimal 3‑node n8n workflow that listens for Stripe payment failures and emails the owner immediately, eliminating manual checks and reducing MRR loss.

Workflow

• 1. Set up a Webhook node in n8n to receive Stripe POST requests.
• 2. Add a Code node to normalize the payload from invoice.payment_failed and charge.failed events.
• 3. Use an HTTP Request node to POST the normalized data to SendGrid (or similar) to send an email alert.

Evidence

This post walks through a tiny n8n workflow that catches every failed Stripe payment and emails you about it the moment it happens.

Wire the Stripe webhook to point at this endpoint, subscribe to invoice.payment_failed and charge.failed, and you get a Slack-worthy alert the second a payment fails.
