The metrics dashboard we hand clients at PxlPeak after shipping a voice agent or chatbot. Every metric here has a target, a diagnostic when it drifts, and a first-response action.

| // n8n Webhook Idempotency — Redis Pattern | |
| // | |
| // Drop this into a Code node immediately after a Webhook Trigger. Prevents | |
| // duplicate processing when the same webhook fires twice (platform retries, | |
| // network hiccups, user double-submits). | |
| // | |
| // This is the single most common production-n8n bug we fix at PxlPeak | |
| // (https://pxlpeak.com) — agencies that skip idempotency ship workflows | |
| // that create duplicate orders, double-charge cards, or spam fulfillment | |
| // queues during retry bursts. |
