API Development & Integration

Connecting the systems you already run, and building the APIs other applications depend on.

Most businesses do not have a single software problem. They have five systems that each hold part of the truth and no reliable way to reconcile them.

Integration work is unglamorous and disproportionately valuable. Done well, data moves automatically and nobody thinks about it again. Done badly, it becomes the most fragile part of the stack.

Integration

We connect accounting platforms, payment providers, CRMs, shipping and logistics services, and internal databases — including legacy systems with awkward or undocumented interfaces.

Building APIs

When your own product needs to be integrated with, we build REST or GraphQL APIs that another developer can work against without calling you: predictable resources, sensible status codes, authentication suited to the consumer, and documentation that is actually current.

The parts people skip

Retry handling for services that go down, idempotency for operations that must not run twice, rate limiting, and a versioning strategy so future changes do not break existing clients.

Common questions

Yes. Extending, documenting and stabilising APIs we did not write is common work, including cases where the original developers are no longer available.
