AI integration

Zapier built by native engineers

Build custom Zapier apps and integrations, or replace brittle Zaps with reliable AI-native workflows.

Overview

What Zapier Integration Development looks like with us

We help fast-moving companies ship Zapier with senior engineers, clear scopes, and honest timelines. We bring production discipline: observability, runbooks, rollback plans, and documented handover to your team. Each project has a named lead engineer, a delivery lead, and a weekly written status so there are no surprises. Whether you're a seed-stage startup or a Fortune 500 modernising legacy systems, the engagement shape adapts to your stage.

What we deliver

01Version-pinning strategy and migration runbook when APIs change
02Native SDK integration — not a hand-rolled HTTP wrapper that breaks on API changes
03Retry / backoff / timeout strategies and dead-letter queues
04Observability: per-call latency, token usage, cost attribution
05Webhook handlers, signature verification, replay safety

FAQs

Common questions

What happens when the upstream API changes?

We pin versions, monitor provider changelogs, and run regression tests against known inputs. When a breaking change lands, we estimate and quote the migration.

How do you handle rate limits and outages?

Retries with exponential backoff, circuit breakers, dead-letter queues, and where appropriate a secondary provider fallback. We instrument everything so you see outages in real time.

What does pricing look like?

Three models: fixed-scope for clear MVPs, monthly retainer for ongoing engineering, or day-rate staff augmentation. We send a written quote within one week of the scoping call.

How fast can we start?

Most engagements kick off within 5-10 business days of the first discovery call. Scoping takes 3-5 days; paperwork (MSA + SoW + NDA) runs in parallel.
