API development and integration that keeps every system talking
Building secure, reliable APIs for smooth system communication and easy integration.
What we deliver
-
REST and GraphQL
Clear, versioned endpoints your web apps, mobile apps and partners can rely on.
-
Payments
Payment gateways connected to your checkout, with the status of every transaction recorded.
-
Third-party tools
Accounting, messaging, shipping and other services connected to your product.
-
Legacy systems
A modern API layer over older software, so you can build on it without replacing it.
-
Security
Authentication, permissions and access limits designed in from the first endpoint.
-
Documentation
API docs your developers and partners can work from without having to ask us.
Sound familiar?
- “Someone copies orders from one system into another every morning.”
- “Our old system still works, but nothing new can connect to it.”
- “The integration breaks and nobody knows until a customer complains.”
Connect what you already have
Most businesses don’t need another standalone tool. They need the ones they have to share data. An API gives two systems a reliable way to talk, so an order placed on your site appears in your accounts, a payment confirms a booking, and nobody has to retype anything.
Built to be depended on
An API becomes part of how your business runs, so we treat it as a product. We write the contract first, agree it with whoever will consume it, and build on Node.js, NestJS, Express.js or Django with MySQL, PostgreSQL or MongoDB. Every endpoint goes through integration testing, and authentication and permissions are designed in from the start.
Kalia shows what this makes possible: a single wallet for loyalty points and cashback, bank offers and discounts collected automatically, and a conversational AI advisor working from the same data.
When the other side is difficult
Third-party services have limits, outages and undocumented behaviour, and legacy systems may have no API at all. We plan for that with retries, logging and alerts, so when something fails your team finds out first and no data is silently lost.
Integration is often one part of a larger build. It sits behind most of our web applications and mobile apps, and it can also be hired on its own.
How a project runs
-
Discover
We list the systems involved, the data that moves and what happens when it fails.
-
Design
The API contract is written and agreed before development begins.
-
Develop
Endpoints and connectors built in short sprints and demonstrated as they’re done.
-
Test
Integration tests against real or sandbox services, including failure cases.
-
Deploy
Staged release with logging and alerts switched on from the first request.
-
Support
Monitoring, updates and fixes when the services you depend on change.

Common questions
What is the difference between an API and an integration?
An API is the interface a system exposes so other software can use it. An integration is the finished connection between two systems, usually built on their APIs. Most projects need some of both.
Can you connect to a system that has no API?
Often, yes. Depending on the system we can work through its database, file exports or a small service built alongside it. We confirm what is possible during discovery.
Do you integrate payment gateways?
Yes. We connect the gateway to your checkout and record the status of each transaction, so failed and refunded payments are handled properly.
Will we get documentation?
Yes. Every API comes with documentation your developers or partners can use without needing us.
Can you maintain an integration after it goes live?
Yes. We monitor it, keep it up to date and fix it when a connected service changes.
