API Development & Integration

Documented, versioned REST or GraphQL APIs and clean third-party integrations that let your systems talk to each other without staff moving data by hand.

API Development & Integration — Robust APIs and seamless integrations that connect your systems

What you get

REST or GraphQL API

A documented, versioned API your apps and partners can build on with confidence.

Third-party integrations

Clean connections to CRMs, payment gateways, ERPs and any external service you depend on.

Webhooks and event systems

Real-time data flow between systems so you stop manually moving information between tools.

API documentation

OpenAPI specs and developer guides so your team — or future partners — can integrate without calling you.

How we work

1

Integration mapping

We map every system that needs to talk to every other, identifying data flows, formats and failure modes.

2

API design

We design the contract — endpoints, data models, authentication — documented and agreed before development begins.

3

Build & test

We build the API with automated tests covering happy paths, edge cases and failure scenarios.

4

Monitor

Production deployment with uptime monitoring, error alerting and logging so failures surface before they become user-facing.

The Cost of Systems That Do Not Talk

Most businesses do not run on one system; they run on five or six — a CRM here, billing there, operations somewhere else, a logistics platform, a marketing tool. The expensive problem is rarely any single tool; it is the gaps between them, bridged by staff exporting a file from one and importing it into another every morning. That manual data movement is slow, error-prone and quietly limits how fast the business can adopt anything new.

API development and integration close those gaps. Sometimes that means building a clean API your own apps, partners or mobile clients can rely on; often it means integrating third-party platforms whose documentation promised a simple connection that turned out to be anything but. Either way the goal is the same: data flowing automatically between systems, so people stop being the integration layer.

How We Design and Build APIs

We begin by mapping every system that needs to talk to every other — the data flows, the formats, and crucially the failure modes, because integrations break at the edges everyone forgets. From there we design the contract: endpoints, data models and authentication, documented and agreed before development starts so there are no surprises when systems meet.

Implementation favours REST or GraphQL depending on the consumers, built with automated tests covering happy paths, edge cases and failure scenarios rather than just the path that demos well. Webhooks and event systems give you real-time flow instead of polling, and every API ships with an OpenAPI specification and developer guides so your team or future partners can integrate without phoning us. Security is standard, not premium: OAuth 2.0, API keys or JWT, rate limiting, input validation and audit logging on every build.

  • Integration mapping of every system, data flow and failure mode
  • Versioned REST or GraphQL APIs with an agreed, documented contract
  • Webhooks and event systems for real-time data flow instead of polling
  • OpenAPI specifications and developer guides for self-service integration
  • OAuth 2.0, API keys or JWT, rate limiting and audit logging as standard
  • Automated tests covering happy paths, edge cases and failure scenarios

Integrations We Handle and How Long It Takes

We have integrated with Salesforce, HubSpot, Stripe, Xero, Shopify, SAP, a range of logistics platforms and most common SaaS tools, so the answer to whether we can connect to your stack is almost always yes. A focused integration or internal API typically runs four to eight weeks; broader API programmes spanning several systems run longer and are delivered in stages.

The clearest sign you need this work is simple: any business running more than two software systems with people moving data between them by hand has an API problem worth solving. Production deployment includes uptime monitoring and error alerting, because an integration that fails silently is worse than no integration at all — failures should surface to us before they ever reach a customer.
