API development
Interfaces designed for the developers who will use them: clear resources, consistent errors, versioning, authentication, rate limiting, documentation and a test environment.
05Data & integration · API & systems integration
API development and systems integration.
An API is the doorway through which one piece of software asks another for something; systems integration is building and connecting those doorways.
We build it to order, around the way you work, or extend and connect the one you already have.
01What it is
In plain words.
An API is the doorway through which one piece of software asks another for something; systems integration is building and connecting those doorways.
A system with no interface is an island. Its data can be reached only through its own screens, which means a person copying and pasting, or a fragile script reading the screen on their behalf.
A well-designed API makes a system usable by other software: your own apps, your partners, your customers' systems and, increasingly, AI agents. Integration work is building those interfaces where they are missing and connecting them where they exist.
02What it includes
Every part, explained.
7 parts. Each can be built by itself; together they are one system.
02
Third-party integrations
Payment gateways, logistics carriers, tax and e-invoicing services, messaging, maps, identity providers and marketplaces, connected through their official interfaces.
03
Legacy system integration
Giving an old system a modern interface without rewriting it: wrapping its database, files or screens so new software can work with it safely.
04
Database integration
Moving and synchronising data between databases of different kinds, with change capture so updates flow as they happen and the source is not strained.
05
SaaS integration
Your cloud applications joined to each other and to your internal systems, with single sign-on and user provisioning handled centrally.
06
Enterprise system integration
ERP, CRM, HR, warehouse and finance systems exchanging orders, stock, customers and postings through their supported interfaces, with the system of record respected.
07
Custom middleware
The layer in between that translates, validates, queues and routes, built when the logic is too specific for a product and too important for a script.
Buy, extend or build?
This is service work by nature: the systems are yours and the connections must be built. Use a vendor's own connector where one exists and works. Build the interface when a system has none, when the standard connector does not carry the fields you need, or when the logic in between is your own.
Where intelligence fits
AI agents are becoming consumers of APIs alongside people and programs. An interface that is well described and tightly permissioned is one an agent can use safely, so we design new APIs with that in mind: clear descriptions, narrow scopes and a full record of every call.
03What it works with
Never on an island.
A system is worth most when it shares its records with the ones beside it.
- Integration platform as a serviceAn integration platform is the switchboard between a company's systems: it carries data from each one to the others that need it.
- Custom enterprise software developmentCustom enterprise software is an application written for one company's way of working, which that company then owns.
- Enterprise resource planningAn ERP is the one system that records what a company owns, owes, buys, makes and sells, so every department works from the same numbers.
- Enterprise AI and intelligenceEnterprise AI is software that reads, searches, reasons and acts on a company's own data and documents, inside the company's own walls.
Part of a family
Data, integration and automation: Systems that talk to each other, work that moves by itself, and numbers you can trust.
04How we build it
Five steps, in the open.
- 01
Listen
You describe the work and where it hurts. We look at the systems and the data you have now.
- 02
Specify
A written specification: what the system does, what it does not, what it connects to and how we will know it works. A clear quote before any work starts.
- 03
Build in stages
A working piece at each stage, on real data, so you steer early. The part that matters most comes first.
- 04
Move the data
Existing records mapped, cleaned of duplicates and reconciled against the old system before anything is switched off.
- 05
Hand over
Training, documentation and the keys. Your team can run it, and we keep it working for as long as you want us to.
One set of records underneath
Customers, products, suppliers, people and stock are each defined once. A second system joins the first; it does not start a competing copy.
Runs where you decide
Your own servers, a private cloud or a cloud account that belongs to you. Customer, employee and financial data stays on infrastructure you control.
Yours to keep
You own the code, the data, the configuration and the documentation. There is no licence fee to us and nothing stopping another team from taking it on.
05Questions
Before you ask.
Questions about API & systems integration
Our old system has no API. Can it still be integrated?
Almost always. We can read and write through its database, exchange files with it, or as a last resort automate its screens, and put a clean interface in front so other systems never touch the old one directly.
How do you keep integrations secure?
Each connection has its own credentials with the least access it needs, secrets are held in a vault, traffic is encrypted, and every call is logged. Security review is part of the specification.
Who maintains the integration when a vendor changes its API?
Whoever you choose. We document every integration and can maintain them under an agreed arrangement, or hand them to your team with the tests that show when something has changed.
