Get Your Systems Talking to Each Other. Secure REST and GraphQL APIs, plus integrations with payment gateways, CRMs, couriers, ERPs and third-party platforms.

Documented APIs your partners can use without guesswork
Payment, courier, CRM and accounting integrations
Secure authentication, rate limiting and logging

Overview

We build APIs that let your website, mobile app and partners share data safely. We also connect your systems to outside services such as payment gateways, courier tracking, CRMs, accounting tools and marketplaces.

Each API is designed with clear endpoints, versioning and documentation. We add authentication, validation and logging, so you can see what is happening and fix problems quickly.

The problem

Data often lives in separate systems that do not talk to each other. Staff re-enter orders, customer details and stock levels by hand, and integrations built in a hurry break without warning.

How we solve it

We design stable APIs and reliable integrations with error handling, retries and alerts. Data moves automatically between systems, and you get documentation so other developers can build on it.

How We Work

01Integration discoveryWe list the systems involved, the data to move and how often.
02API designWe define endpoints, data formats and security in an OpenAPI specification.
03DevelopmentWe build the API or connectors with validation and error handling.
04TestingWe run automated and manual tests against sandbox and live services.
05Deployment and monitoringWe deploy, add logging and alerts, and hand over documentation.

Frequently Asked Questions

REST or GraphQL: which is better?

REST is simple and widely supported. GraphQL suits apps that need flexible data queries. We recommend based on who will use the API and how.

Can you integrate local payment gateways?

Yes. We can integrate international gateways such as Stripe and local gateways that provide a documented API.

What happens if a third-party service goes down?

We build in retries, queues and alerts so data is not lost and your team knows when something fails.

Do you document the API?

Yes. Every API comes with an OpenAPI specification and readable documentation.
