API & Integration

Every system speaking the same language.

We design APIs and integration layers that move data reliably between applications, devices, partners and third-party services.

API & System Integration

Value is lost when systems cannot talk to each other: duplicate entry, stale data and manual reconciliation.

We build integration architecture — APIs, webhooks, message queues and connectors — that is secure, observable and resilient to failure.

Business challenges

What usually stands in the way.

01

Manual data transfer

Staff re-key information between disconnected systems.

02

Brittle point-to-point links

Undocumented scripts break when one system changes.

03

Third-party complexity

Payment, messaging and government APIs each behave differently.

04

Device protocols

Hardware and IoT devices use proprietary binary protocols.

Our solution

How we solve it.

A deliberate integration layer with versioned APIs, retries, monitoring and clear documentation replaces fragile one-off connections.

  • REST and GraphQL API design with OpenAPI documentation
  • Event-driven integration with queues and webhooks
  • Connectors for payment, messaging, ERP and CRM platforms
  • Protocol decoders for telematics and IoT devices
  • Authentication, rate limiting and audit logging

Development approach

Four stages. Clear outcomes.

  1. Step 1

    Inventory

    Catalogue systems, data flows and ownership.

  2. Step 2

    Design

    Define contracts, schemas and error handling.

  3. Step 3

    Connect

    Build, test and document each integration.

  4. Step 4

    Monitor

    Track throughput, failures and latency.
