Integrations that don’t break at 3am.
Idempotent, retry-safe, observable integrations across your CRM, ERP, payments, and comms — engineered for the messy real world, not the happy path.
API integration services build reliable, observable data pipelines between business systems — CRM, ERP, payments, comms. Unlike iPaaS tools such as Zapier or Make, custom integrations are idempotent, retry-safe, monitored, and fully owned by the customer.
- 01Production integrations require idempotency, retries, DLQs, and observability.
- 02iPaaS tools cost more than custom workers past moderate volume.
- 03Reconciliation jobs catch what the streaming path misses.
Zapier and Make solve simple integrations well. They fall over when the volume grows, when partial failures matter, or when compliance requires audit trails.
Production integrations need idempotency, retries with backoff, dead-letter queues, observability, and clear ownership. We build integrations at that standard — usually as small, focused workers you can run yourself.
What breaks without a specialist.
Silent failures
iPaaS tools drop messages without alerting; nobody notices until reconciliation.
Duplicate writes
Non-idempotent handlers create duplicate CRM records, duplicate invoices, duplicate emails.
Cost spikes with volume
Per-task pricing punishes success.
Vendor lock-in
Complex flows in proprietary iPaaS tools can’t be migrated.
The approach.
Idempotent handlers
Every write is safe to retry. Duplicate protection via natural keys or dedupe tokens.
Retries + DLQ
Exponential backoff, jitter, and a dead-letter queue with alerting.
Observability
Structured logs, metrics, traces — plus a dashboard that shows message throughput and failure rate.
You own it
Standard TypeScript workers in your infrastructure. No proprietary ‘flow’ artifacts.
Features included.
Webhook receivers
Signed, verified, and idempotent.
Sync workers
Batch and event-driven sync between systems of record.
Enrichment
Third-party data (Clearbit, Apollo, etc.) added inline on ingest.
Reconciliation
Nightly diff jobs catch anything the streaming path missed.
Compliance
Field-level encryption, PII redaction, GDPR delete flows.
SLA monitoring
Business-metric alerts (e.g., no leads synced in 15 minutes) — not just infra alerts.
What changes for you.
Fewer surprises
Integrations we ship typically run 99.9%+ availability with alerting that catches the 0.1%.
Predictable cost
Flat hosting cost instead of per-task pricing.
Ownership
Standard code your engineers can maintain.
Our process.
Discovery workshop
A 60-minute working session with your team to map goals, constraints, competitors, and success metrics. You leave with a written scope and a fixed price — no estimates, no surprises.
Strategy & architecture
We produce an information architecture, content plan, and technical blueprint. Every screen and endpoint is documented before a line of code is written.
Design in the browser
High-fidelity design happens inside the real product, not in Figma. You review clickable states, not static screens — which is why our sign-off cycles are 3× faster than agencies.
Build & integrate
Engineering happens in weekly milestones. You get a staging URL from day one, so you can watch the product take shape rather than wait for a big-bang reveal.
Launch & measure
We ship, monitor Core Web Vitals for 14 days, and hand over a written performance report. Analytics, tracking, and conversion goals are wired in before launch — not after.
Grow
Optional monthly retainer for iteration, experiments, and SEO. You own the code either way — no lock-in, no dark patterns.

Answers.
Zapier / Make vs custom integrations?+
For low-volume, non-critical flows, iPaaS is fine. For high-volume or business-critical flows — payments, orders, CRM sync — custom integrations are cheaper, more reliable, and observable.
How much does one integration cost?+
Simple point-to-point integrations start at $2,500. Complex multi-system flows with reconciliation and monitoring range $8k–$30k.
