Real-time webhook debugging for developers
Why HookCheck
One debugger, every stack
HookCheck gives developers a temporary, shareable endpoint to inspect, replay, and debug webhook payloads without touching production infrastructure. Spin up a listener in seconds, capture raw headers and bodies, and forward events to your staging environment when you're ready.
Whether you're integrating Stripe, Shopify, GitHub Actions, or a custom event bus, HookCheck sits between your provider and your code so you can catch malformed payloads, missing signatures, and retry storms before they hit your database. Every session generates a timestamped log, supports curl replay commands, and auto-destroys after 24 hours — no accounts, no persistence, no surprises.

How teams use HookCheck in production
Payment reconciliation at Paygate
Paygate's backend team uses HookCheck to validate Stripe and Adyen webhook payloads during every release cycle. When a new payout run introduced a race condition between charge.succeeded and transfer.completed events, the team spun up a HookCheck listener, replayed the exact sequence from their Stripe CLI, and identified a missing idempotency key in their reconciliation service. The fix was deployed within four hours instead of the usual two-day regression cycle. Paygate now runs HookCheck sessions in every staging pipeline to catch duplicate notifications and signature verification failures before they reach production.
Order fulfillment automation at Stockline
Stockline, a mid-market e-commerce platform handling 12,000 orders daily, relies on HookCheck to debug Shopify and Magento 2 webhook integrations across their multi-region fulfillment centers. When their 3PL partner changed the structure of orders/fulfillments/update payloads, Stockline's inventory sync stopped processing backorders. Using a HookCheck endpoint, the team captured the new payload, compared it against their schema, and discovered a renamed field (tracking_company → carrier_name) that broke their parser. HookCheck's replay feature let them test the patched service against historical events before flipping the deploy. Stockline's engineering lead, Mira van der Meer, reports that HookCheck cut their webhook-related incident response time from an average of 6 hours to under 45 minutes.
Multi-tenant event routing at CloudSync
CloudSync builds a SaaS platform that routes webhooks from over 40 third-party services into tenant-specific event buses. Their infrastructure team uses HookCheck to isolate and debug routing failures without affecting live customers. During a migration from their legacy NATS cluster to Apache Pulsar, several tenants experienced dropped user.created events. By inserting a HookCheck proxy in front of the new Pulsar consumer group, the team captured every incoming payload, identified a TLS certificate mismatch that caused silent 403 rejections, and verified the fix by replaying 200 captured events against the corrected endpoint. CloudSync's CTO, Daniel Okeke, now requires HookCheck validation for every webhook pipeline change, and the team has reduced multi-tenant outages by 73% over the past year.
