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

说明与用途

一个最小化的3节点n8n工作流，实时通过电子邮件通知Stripe支付失败，消除手动检查。

问题

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

结果

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

工作流

• 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.

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.
