What we build · API Development & Integration

APIs and integrations that make your systems talk.

APIs are how your systems stop working in isolation. We design and build the integrations, services, and data pipelines that let your tools share one version of the truth.

The work

Integrations that end the manual re-entry.

We have used APIs in nearly every system we have built, because getting separate tools to agree is where most projects strain. We design the contract first: what data moves, who owns it, and what happens when a call fails. Then we build the integrations and services around it, so information flows instead of being rekeyed by hand between systems that were never meant to talk. See how we scope it →

Sound familiar?

Sound like where you are?

Is this you?
01

Your systems don't talk

Data gets exported, reformatted, and rekeyed by hand between tools that should share it automatically.

02

The integration keeps breaking

A third-party API changed, a sync failed quietly, and nobody knew until the numbers were already wrong.

03

You're building on someone's platform

You need to connect to a payment processor, an ERP, or a partner's system, and the docs only get you halfway.

You'll see the contract

Before a line of code, you will have seen the data contract and approved the number. Requirements by Design maps every system, field, and failure case first, the fixed bid is committed in the room, and the work arrives in sprints you can use. See the full method →

What that includes

What an API and integration build covers.

01

Custom API development

The APIs your own products expose, versioned and documented so others can build on them safely.

02

Third-party integrations

Payment processors, ERPs, CRMs, and partner systems, connected and kept working as they change.

03

Data pipelines and sync

Reliable movement of data between systems, with the retries and checks that keep it correct.

04

EDI and legacy connections

The older, stricter protocols that big partners still run on, handled without drama.

05

API architecture

The contracts, auth, rate limits, and error handling that decide whether an integration lasts.

06

Monitoring and support

We watch the integrations we build, so a failed sync surfaces before it costs you.

The proof

Integrations we built that are still running.

Each of these moves real data between real systems, and we still keep them running today.

The challenge it solves

This is part of a new build.

APIs and integrations are how a new system fits the ones you already run. See where that work sits among the four kinds of hard on What We Build.
