Catch payment failures before revenue loss compounds
NotiLens monitors your payment flow, webhook health, failure rates, and broken checkout sequences — alerting your team the instant something stops working, not when a customer reports it.
Payment failures compound silently
A 10% failure rate doesn't look alarming in a weekly report. But over a 4-hour window, it can represent thousands of dollars in lost revenue — and dozens of frustrated customers.
Failure rate climbed without a single alert
Your card decline rate crept from 2% to 11% over two hours. No alert fired because your monitoring only watched for complete outages. Revenue was bleeding the entire time.
Webhook delivery stopped
Stripe kept sending events, but your endpoint was timing out. Orders were created in Stripe, but never fulfilled. Your team found out from an angry customer escalation.
Broken payment flow went undetected
A discount code bug issued a refund on every transaction for 90 minutes. It showed up as "normal activity" in the Stripe dashboard — until the end-of-day reconciliation.
Payment intelligence at every step
NotiLens tracks the full payment lifecycle — from initiation to completion — and alerts you when any step breaks, stalls, or spikes.
Payment flow monitoring
Track the journey from payment.initiated to payment.completed. If a transaction starts but never finishes, NotiLens detects the gap and alerts you with a count and time window.
Failure rate anomaly detection
NotiLens computes a rolling failure rate baseline. The moment your current rate exceeds it by your configured multiplier, you get an alert — not a dashboard to check.
Webhook health tracking
Monitor the arrival of Stripe or PayPal webhook events. If delivery stops for more than your configured silence window, NotiLens alerts you before fulfillment breaks.
Broken flow detection
Define that stripe.payment_intent.succeeded must follow stripe.payment_intent.created within 5 minutes. If the completion event never arrives, NotiLens fires — catching silent processing failures before they compound.
Subscription anomaly detection
Track pause, cancel, and downgrade events as a rate. When same-hour churn spikes beyond your baseline, NotiLens fires — before it shows up in your weekly MRR report.
Acknowledgement (ACK)
Critical payment alerts repeat every 5 minutes until someone on your team acknowledges them. A webhook outage at 3am won't go unnoticed until it becomes a financial crisis.
What NotiLens sends your payments team
Every alert includes the specific metric, the deviation from baseline, and the context to act — no dashboards to dig through.
When webhooks stop arriving, your payments are still processing — but your fulfillment is broken.
NotiLens detects the silence in your webhook stream before you start getting customer emails. Most payment monitors only track failure events — NotiLens also tracks when events stop coming altogether.
