SDK Development in Hereford
Client libraries that make a Hereford company's API quicker to adopt. An SDK is a commitment rather than a deliverable — each language you publish is one you maintain, version and support indefinitely, so two well-kept libraries beat five that fall behind the API.
Why this comes up
The problem
Integrators write the same authentication, retry and pagination code against your API, each slightly differently. Support answers the same questions repeatedly, and integrations take weeks.
What you get
What we deliver
- Languages chosen from what your integrators actually use, not a broad sweep
- Idiomatic design, since a library that ignores a language's conventions is unpleasant to use
- Authentication, retries, pagination and errors handled inside the library
- Generated from your API specification where possible, so it tracks changes
- Published to the standard package registry with semantic versioning
- Examples that run, because a broken quickstart costs more than missing documentation

SDK Development in Hereford — common questions
- Which languages should we support?
- The ones your integrators use, which you can find from your own traffic and support tickets. Publishing six SDKs to look comprehensive means six to maintain, and an abandoned library is worse for adoption than never having shipped one.
- Should SDKs be generated or hand-written?
- Generated from an OpenAPI specification for the bulk of it, so the library tracks the API automatically, with hand-written ergonomics on top. Fully hand-written libraries drift; fully generated ones are usually awkward to use.
- What belongs in the SDK rather than the caller's code?
- Authentication and token refresh, retries with backoff, pagination, and turning error responses into typed errors. Those are the things every integrator otherwise reimplements, and where their versions differ from each other in quality.
- How do we handle breaking API changes?
- Semantic versioning honestly applied, and a migration note when a major version lands. Shipping a breaking change in a patch release destroys trust quickly — integrators pin versions precisely because they have been caught before.
- Do you work with businesses across Herefordshire?
- Yes. We are based in Leicester, United Kingdom and work with clients throughout West Midlands, including Hereford and the surrounding Herefordshire area. Most collaboration happens remotely, and we travel for kick-offs and key milestones.
- What kind of Hereford businesses do you usually work with?
- Food and drink production systems with traceability, built to work where rural connectivity is unreliable. Beyond that we work across Agriculture, Food & Drink, Manufacturing, Defence and Tourism.
- Do you cover the areas around Hereford?
- Yes — we work throughout West Midlands, including Worcester, Gloucester, Birmingham. Hereford is an urban area of roughly 60,000+, and we take on work across the wider Herefordshire region rather than the city boundary alone.
