What the user sees when the integration goes down
Two systems built by different teams rarely agree on what a retry means, or what happens when a webhook never arrives. We define the contract between them — idempotency keys so a retried write can't double-charge anyone, webhook verification and replay after an outage, reconciliation when a callback never comes back. Most integrations skip what the user sees while any of that is happening; we design that screen too.

When is the perfect time for API & Integrations?
Payments double-charge on retry
A network blip causes a client to retry a write, and without an idempotency key the same charge or order goes through twice.
A webhook never arrived
An outage on either side means an event fires but the callback never lands, and the two systems end up disagreeing about what happened.
Two systems need to talk for the first time
A new integration is being built between platforms that were never designed with each other in mind, past matching field names.
The integration used to work
A partner's API changed shape or tightened its rate limits, and what used to work reliably now fails in ways nobody notices until a customer complains.
A new partner or provider is joining
Expansion brings a new system into the stack, each with its own retry behavior, error codes and webhook guarantees to account for.
Reconciliation is a manual spreadsheet
Someone checks two systems against each other by hand at the end of the day because nothing catches the mismatch automatically.

The API & Integrations Roadmap
Integration audit
We map both systems' actual behavior — error codes, retry defaults, webhook guarantees — rather than trusting the documentation each vendor publishes.
Contract design
A written contract defines idempotency, retry behavior and error handling between the two systems, so both sides agree on what a retry or a missing callback means.
Build and verification
Idempotency keys, webhook verification and reconciliation are built and tested against real failure scenarios: dropped webhooks, duplicate sends, out-of-order delivery.
Failure-state design
The user-facing screen for a mid-failure state is designed and built alongside the integration, not left as a generic error page after launch.
Monitoring handoff
Alerting is tuned to the failure modes that matter and handed to the team, with the reconciliation process running on a schedule going forward.

Who Can We Engage?
Startups
Teams who need to prove something works before it is funded, and who cannot afford to spend the runway finding out late.
Enterprises
Organizations with systems they cannot switch off, where new capability has to arrive alongside what is already running.
Product Teams
In-house teams who need engineering capacity that carries context between sprints rather than rotating off the account.

FAQS
Common questions about API & Integrations.
No. A low-stakes, easily retried call — pulling a public data feed, say — doesn't need idempotency keys or a reconciliation process. If the worst case is 'nothing happens and you try again later,' we'd rather talk you out of the extra engineering than sell it to you anyway.
Depends what the retry does. A retry without an idempotency key doesn't prevent a duplicate — it just makes one more likely. The question is what happens on the second attempt, not whether one happens at all.
Usually a generic error page or a spinner that never resolves, while the backend is still sorting out what happened. That gap is where most support tickets about integrations come from.
Yes — auditing an existing integration for these gaps is usually the starting point, since most were built without this rigor from day one and the failure modes only show up under real traffic.
Reconciliation. If nothing catches a missing event within a set window, a scheduled check against both systems' records finds the mismatch and resolves it before a customer has to report it.
