APIs that keep the other systems honest

Most of the APIs we ship sit between a mobile app, a council portal, and something that still speaks SOAP. Contracts, keys, and versioning — not a JSON dump with a public URL.

Frequently Asked Questions

A list of the systems that have to talk, sample data or API docs if they exist, and what the first real job is — for example “push new orders into Xero.” We come back with a scope, not a rate card.

Yes. Most of the work is sitting between a CRM, finance package, mobile app, or an older system that only speaks SOAP. We read the existing contract first and only build what is missing.

A focused integration is often three to six weeks. A new API that several apps will share takes longer, which we flag after the first workshop.

Yes. Endpoints, auth, and example calls go in a short doc your developers can use. Staging stays up until you have tried it yourselves.

We can. A retainer covers monitoring, versioning, and the next consumer. If your team wants to own it, we hand over repo access and the runbook.
