Stripe webhooks
Invoice finalized. Where's the payment event?
Stripe retries aren't guaranteed, event ordering isn't strict, and invoice.paid can silently never arrive. Relin monitors every Stripe webhook lifecycle and alerts you when events go missing.
Failure modes Relin detects
Invoice finalized, never paid
invoice.finalized arrived 6 hours ago. No invoice.paid, payment_failed, or voided event followed.
Charge exists in Stripe, no webhook received
Stripe API shows 3 charges in the last hour with no corresponding charge.succeeded webhooks in the ledger.
Duplicate delivery after timeout
Same invoice.payment_failed event received twice. Idempotency key matched — duplicate delivery attempt recorded, not double-processed.
Lifecycle monitoring
Relin tracks Stripe invoice, subscription, charge, and payment intent state machines. Missing terminal events trigger alerts automatically.
API reconciliation
Relin polls stripe.invoices.list and diffs against the event ledger. Finds events you were never sent a webhook for.
One-click replay
Replay missing or failed events from the ledger to your endpoints. No Stripe support tickets, no scripts.
Your Stripe webhooks are probably fine. Probably.
