HEARD: A silent webhook failure was eating 6% of orders.

HEARD: A silent webhook failure was eating 6% of orders.
A Shopify-to-fulfillment team told us their Zapier-style integration looked green for a year — until reconciliation showed orders that never reached the 3PL. The culprit: webhooks that timed out got dropped with no retry.
The fix was unglamorous: a queue with exponential backoff and a dead-letter log. Recovered orders that week alone covered the engineering time.
— ~6% of orders had been silently failing
— Post-fix mismatch dropped to under 0.2%
The insider line: 'green dashboards lie; reconcile against source of truth.'
Watch this.
