System Integrations & API Development

Connecting the tools you already run into one coherent system.

← Back to Software Development

Overview

Most businesses don't have one system — they have ten, each holding a piece of the picture, none of them talking to each other. We build the integrations and APIs that connect them, so data moves automatically instead of being re-typed by someone on your team.

This ranges from connecting two off-the-shelf tools via their existing APIs, to building a custom API layer that exposes your own systems to partners, apps, or internal tools that need them.

Business problems solved

The same customer data living in your CRM, your billing system and your support tool — all slightly out of sync. A team member whose entire job is manually moving data between systems. A partner or client who needs programmatic access to your data and there's no API to give them.

Our approach

We map every system in the chain, understand exactly what data needs to flow where and how often, then build the integration to be resilient — handling failures, retries and rate limits gracefully rather than silently dropping data when one system hiccups.

For custom APIs, we design against real consumers of that API (your own app, a partner, a mobile client) rather than building a generic API nobody asked for.

Process

  1. 01

    Map the systems

    Document every system involved, what data it owns, and what it needs from the others.

  2. 02

    Design the integration

    Define the data flow, error handling and retry strategy before writing code.

  3. 03

    Build & test

    Build against real sandbox data, including the failure cases, not just the happy path.

  4. 04

    Monitor in production

    Alerting on sync failures so issues surface immediately, not weeks later.

  5. 05

    Document & hand off

    Clear documentation of what connects to what, and why, for whoever maintains it next.
