<p>Docs say "exponential backoff" but I want to know the exact schedule so I can tune our endpoint's idempotency window. Anyone got the numbers?</p>

<p>Schedule for the standard tier: 1m, 5m, 30m, 2h, 12h, 1d, 3d, 7d. After 7 days the event moves to the dead-letter queue and we email your account's webhook contact. Total of 8 attempts over a 7-day window. Enterprise can configure custom curves.</p>
<p>Tune your idempotency window to at least 7 days — we've seen integrations where a delivery success on attempt 8 conflicted with a manual retry someone did at hour 6, leading to double-processing.</p>
