Webhooks & Event-Driven Architecture
Reliable webhook systems and event-driven backends that react to real-time events instead of relying on slow, resource-heavy polling.

Polling for changes wastes resources and introduces delay, but webhooks done wrong bring their own problems: missed events, duplicate processing, and no way to recover when a receiving endpoint goes down. Building this correctly means handling failure modes that only show up under real production conditions.
Missed webhooks with no way to know
A webhook fires, the receiving endpoint is briefly down, and the event is gone forever with no record it ever happened. Without retry and dead-letter handling, silent data loss becomes a recurring, undetected problem.
Duplicate processing corrupting data
The same webhook fires twice, or a retry lands after the original already succeeded, and downstream systems process the event twice. That duplication shows up as double-charged customers or duplicated records with no obvious cause.
A system built on polling that can't scale
Checking for updates every few seconds across thousands of records burns compute and still introduces meaningful delay. As volume grows, the polling approach that worked at small scale becomes the actual bottleneck.
What you get.
Reliable webhook receivers with signature verification
Incoming webhooks are verified against provider signatures and processed idempotently, so spoofed or duplicate events don't corrupt your data.
Retry and dead-letter queue handling
Failed webhook deliveries are retried automatically with backoff, and persistent failures land in a dead-letter queue for review instead of vanishing silently.
Event-driven backend architecture
Core system logic is restructured around events rather than polling loops, so state changes propagate immediately instead of on a delay.
Outbound webhook system for your own platform
If your product needs to notify integrators of events, a full outbound webhook system is built with retries, signing, and delivery logs on your end.
Idempotency guarantees
Every event is processed with idempotency keys, so a duplicate delivery is safely ignored instead of being applied twice.
Monitoring and replay tooling
Webhook delivery and processing are logged and monitored, with the ability to manually replay a failed event once the underlying issue is fixed.
Four steps, no mystery.
Quick scoping call
A short call (or async over WhatsApp) to understand what you're working with and what "done" actually looks like for you.
Fixed scope, no surprises
A clear written plan of what's included and how long it takes, before any work starts.
The actual work
Progress you can see, not a black box. You get updates as milestones land, not just a status report at the end.

Frequently asked.
Polling checks for changes on a fixed interval regardless of whether anything happened, wasting resources and adding delay; webhooks push events the moment they occur, which is faster and far more efficient at scale.
