Quick overview
Quick overview Verify Stripe signatures, route typed events, alert Slack/Discord/email, and ignore duplicate event IDs. How it works Receives a POST webhook request from Stripe with the raw request body enabled. Verifies the Stripe-Signature header against your webhook secret (or optionally skips verification via an environment flag) and extracts key event fields like type, amount, customer, and object IDs. Checks the Stripe event ID against workflow static data to prevent processing the same event more than once. Immediately returns HTTP 200 with a “duplicate” response when the event was already seen. Maps the Stripe event type to a severity/title, builds Slack/Discord message bodies and a Resend email payload, and enables channels based on configured environment variables. Sends the alert to Slack and/or Discord via incoming webhooks and to email via the Resend API, recording any send errors without failing the webhook. Appends a compact log entry to workflow static data and responds to Stripe with HTTP 200 including the event ID, type, severity, and notification results. Setup Create a Stripe webhook endpoint pointing to this workflow’s webhook URL (path stripe-ops) and configure Stripe to send the event types you care about. Set STRIPE_WEBHOOK_SECRET (and optionally STRIPE_TOLERANCE_SEC) in your n8n environment to enable signature verification. To receive alerts, set SLACK_WEBHOOK_URL and/or DISCORD_WEBHOOK_URL, and for email set RESEND_API_KEY, ALERT_FROM_EMAIL, and ALERT_TO_EMAIL. If needed, adjust IDEMPOTENCY_MAX_IDS to control how many Stripe event IDs are kept for de-duplication, and avoid using STRIPE_SKIP_VERIFY=true except for local testing. Requirements n8n 1.40+; env STRIPE_WEBHOOK_SECRET; optional SLACK_WEBHOOK_URL, DISCORD_WEBHOOK_URL, RESEND_API_KEY, ALERT_FROM_EMAIL, ALERT_TO_EMAIL Customization Toggle alert channels via env vars (empty skips). Adjust IDEMPOTENCY_MAX_IDS. STRIPE_SKIP_VERIFY=true for local curl tests only. Additional info Honest limits: Idempotency uses workflow static data (per instance, last 2000 IDs), not a database. HMAC needs the raw body. Alerts only — does not capture/refund/update Stripe objects. STRIPE_SKIP_VERIFY=true is for local tests only.
