Service · API Integration

Make your systems talk to each other — reliably.

We connect the platforms your business depends on, handling the hard parts — auth, rate limits, retries, failures — so the integration holds up in production.

API Integration
Typical timeline
2–4 weeks to live
Engagement
Fixed scope, phased
Support
Post-launch plans

Works with

  • REST & GraphQL
  • Webhooks
  • n8n
  • Make
  • Custom middleware
  • Message queues
The problem

Disconnected systems mean people copy data between them by hand. Naive integrations break quietly: a token expires, an API changes, a rate limit is hit, a record fails to sync and no one notices until something's wrong downstream.

  • Staff manually move data between tools
  • Existing integrations fail silently
  • No visibility when a sync breaks
  • Point-to-point connections that multiply and tangle
Our approach

We build integrations designed for production: proper authentication and token refresh, respect for rate limits, retries with backoff, dead-letter handling for failures, and monitoring that alerts you when something needs attention. Where it makes sense, we centralise flows rather than adding more point-to-point links.

  • Robust auth, rate-limit handling and retries
  • Failure handling and alerting, not silent drops
  • Idempotent syncs that don't duplicate or lose data
  • Centralised flows instead of tangled point-to-point links
What's included

Inside every API Integration engagement

System connections

Two-way sync between CRM, ERP, finance, support, marketing and custom systems.

Production-grade reliability

Token refresh, rate-limit backoff, retries and idempotency handled properly.

Monitoring & alerts

Dashboards and alerts so a broken sync is noticed and fixed fast.

Transformation logic

Mapping, validation and business rules applied as data moves between systems.

How it works

From first call to live in weeks, not quarters

Every phase has a defined output you can review before we move on.

  1. 01

    Map the data flows

    We document which systems need to share what data, in which direction, and how often.

  2. 02

    Design the integration

    We choose the pattern — direct, middleware or event-driven — and define transformations and error handling.

  3. 03

    Build and test

    We develop the integration and test it against real data, including failure scenarios.

  4. 04

    Deploy and monitor

    We put it live with monitoring and alerting, and stay on to handle API changes.

Use cases

Where teams put this to work

CRM ↔ finance sync

Deals, invoices and payments kept consistent between your CRM and accounting system.

Unifying customer data

Support, product and marketing systems sharing one accurate view of each customer.

Replacing a broken Zap

A fragile no-code integration rebuilt as something that holds under real volume.

Technology

Built on tools that hold up in production

We choose the stack for the job. Listing a tool here doesn't imply a partnership.

  • REST & GraphQL
  • Webhooks
  • n8n
  • Make
  • Custom middleware
  • Message queues
Outcomes

What changes after launch

  • No more manual copying between systems
  • Integrations that survive API changes and outages
  • Alerts when something needs attention
  • Consistent data across every connected tool
  • A cleaner architecture as you add more systems

API Integration — common questions

Ask a question

Yes. We often start by stabilising fragile Zapier or Make flows, then rebuild the ones that can't be made reliable.
