When an integration silently fails, users blame the product — not the integration.
Broken integrations are support tickets, churned users, and damaged trust. Whether it's a Stripe webhook that stopped processing, a HubSpot sync that's writing duplicates, or a Zapier trigger that fires inconsistently — we diagnose the failure, fix the implementation, and add the observability that catches failures before users do.
Third-party integrations that are unreliable — failing silently, processing duplicate events, or syncing data incorrectly — causing support tickets and user frustration
Integration failures are uniquely frustrating because they're often invisible. A broken database query throws an error immediately. A broken webhook handler might process 90% of events correctly and silently drop 10% — the ones that happen to have a specific edge case in the payload, or that arrive during a high-traffic period when the handler is slow to respond.
The common integration failure patterns:
Stripe webhook failures. The webhook handler doesn't respond within Stripe's timeout (30 seconds) — possibly due to a slow database query — and Stripe marks the delivery failed. Stripe retries with exponential backoff, but if the underlying issue isn't fixed, the retries fail too. The invoice.payment_succeeded event is never processed. The user paid but still shows as unpaid in the application.
Missing idempotency. Stripe (and most webhook systems) deliver events at-least-once — if there's any doubt about delivery, they retry. A handler without idempotency keys processes the event twice: the user is charged twice, the record is created twice, or the email is sent twice.
OAuth token expiration. A HubSpot or Salesforce integration uses an OAuth access token that expires after 60 minutes. The token refresh logic has a bug — it refreshes correctly when the token is used within 24 hours, but fails after a 48-hour weekend gap. The integration appears to work, then fails every Monday morning.
Rate limit handling. Third-party APIs have rate limits. Integrations that don't implement retry-with-backoff on rate limit responses fail during high-activity periods.
Integrations that work reliably with proper error handling, idempotency, logging, and the monitoring to catch failures proactively
Root cause analysis
Review of integration logs, Stripe webhook delivery history, and error traces to identify the exact failure mechanism. Written diagnosis before any code changes.
Idempotency implementation
Every webhook handler given idempotency keys — the event ID is recorded on first processing, and duplicate deliveries are detected and skipped.
Error handling and retry logic
All external API calls wrapped in error handling with exponential backoff retry for transient failures (rate limits, temporary unavailability) and immediate failure for permanent errors (invalid credentials, not found).
Token refresh reliability
OAuth token refresh logic reviewed and hardened. Refresh tested against the edge cases (refresh shortly before expiry, refresh after extended gap).
Integration monitoring
Logging for all integration events with Sentry alerts for failure rates above baseline. Proactive alerting before users notice.

Three steps, every time.
The same repeatable engagement on every project. No surprises, no mystery, no billable ambiguity.
Brief & discovery.
We send you questions, then get on a call. Output: a written scope with every step, feature, and integration listed.
Build & ship.
Fixed schedule, weekly reviews. No scope creep unless you change the scope — and if you do, we reprice it transparently.
Warranty & retainer.
30-day warranty on every launch. Most clients stay on a monthly retainer for ongoing features and maintenance.
Why Fixed-Price Matters Here
Integration repair scope is defined by the diagnosis — the specific failure mode and the fix. Fixed price after the diagnosis.
Related engagements.
Questions, answered.
Yes. The diagnosis starts with the code — how the integration is implemented, what logging exists, and what the failure pattern is. Prior history with the codebase isn't required to diagnose and fix an integration failure.
Some failures are in the third-party API — rate limits, service outages, schema changes. When the failure is external, the fix is defensive: better retry handling, better error logging, and monitoring that distinguishes external failures from internal ones.
Integration diagnosis and repair: from $5k. Reliability overhaul of a suite of integrations: from $15k. Fixed-price.
