API Audit in York
An API audit for York organisations, starting from the question that governs everything else — who is calling this, and would you know if you broke them. An interface whose consumers cannot be enumerated cannot be changed safely, which is why so many teams are maintaining endpoints they suspect nobody uses.
Why this comes up
The problem
Nobody can say which partners depend on the older endpoints, so nothing has been changed or removed in three years.
What you get
What we deliver
- Consumers identified from traffic, keys and logs rather than from memory
- Endpoints ranked by real usage, exposing what is genuinely dead
- Versioning approach reviewed, including how a breaking change would be handled
- Authentication examined — key age, rotation, scope and what a leaked key permits
- Rate limiting and abuse protection checked at the edge
- Documentation compared against actual behaviour, since these drift apart quickly

API Audit in York — common questions
- How are unknown consumers found?
- Through the traffic itself. Access logs, key usage and user agent patterns identify who is actually calling and how often, which usually reveals both integrations nobody documented and partners still using an endpoint that was deprecated years ago.
- Why does key rotation come up?
- Because keys issued at integration time tend to live forever. A credential given to a partner five years ago, still valid, possibly shared internally with people who have since left, is a standing exposure — and rotating it requires knowing who holds it, which is why the consumer inventory comes first.
- What if documentation and behaviour disagree?
- Assume integrators have built against the behaviour. Once a discrepancy exists, someone somewhere depends on what the API actually does rather than what the documentation claims, so correcting the documentation is safe and correcting the behaviour may not be.
- Can we remove unused endpoints?
- Once you can demonstrate they are unused, yes — and the demonstration is the whole difficulty. A period of monitoring, a deprecation notice to identified consumers and a defined removal date turns an indefinite maintenance obligation into a scheduled piece of work, which is usually the main reason this audit pays for itself.
- Do you work with businesses across North Yorkshire?
- Yes. We are based in Leicester, United Kingdom and work with clients throughout Yorkshire & the Humber, including York and the surrounding North Yorkshire area. Most collaboration happens remotely, and we travel for kick-offs and key milestones.
- What kind of York businesses do you usually work with?
- Visitor-facing booking and ticketing systems that handle extreme seasonality on a small operator's budget. Beyond that we work across Tourism & Heritage, Rail Engineering, Bioscience, Retail and Higher Education.
- Do you cover the areas around York?
- Yes — we work throughout Yorkshire & the Humber, including Leeds, Newcastle, Sheffield. York is an urban area of roughly 210,000+, and we take on work across the wider North Yorkshire region rather than the city boundary alone.
