Tray.io Development in York

Building on Tray.io for York organisations, where the first question is whether the integrations are yours or your customers'. Internal workflows and integrations embedded in a product you sell are different disciplines — one is operations work, the other is a feature with support obligations, versioning and customers who notice when it breaks.

Why this comes up

The problem

Customer-facing integrations were built with the same conventions as internal operations workflows.

What you get

What we deliver

  • Internal and customer-facing integrations separated in design and in ownership
  • Embedded integrations versioned, since customers cannot be changed underneath
  • Error handling built for customers rather than for an internal operator
  • Authentication designed so each customer's credentials stay isolated
  • Support path defined for when a customer's integration fails
  • Workflows structured with reusable components rather than duplicated per customer

Working in York

Yorkshire & the Humber

York's economy leans heavily on heritage tourism, and the practical constraint here is often that a visitor-facing system has to handle enormous seasonal swings on a small operator's budget.

Tray.io Development in York — common questions

Why separate the two kinds?
Because the obligations differ entirely. An internal workflow that fails is an inconvenience somebody fixes; a customer-facing integration that fails is a support ticket, possibly a breach of what you promised, and something you cannot simply change while they are using it.
What does versioning involve?
Not altering behaviour customers depend on. An embedded integration in use by hundreds of accounts cannot be edited the way an internal workflow can, so changes need a path that lets existing customers continue while new behaviour is introduced.
How should errors reach customers?
As something actionable rather than a technical message. A customer whose integration failed needs to know what to do — reconnect, fix a value, contact you — and an internal error string passed through unchanged generates a support conversation instead.
How are credentials kept separate?
Through per-customer authentication rather than shared connections. Each customer's access must be isolated so one cannot reach another's data, which is straightforward when designed in and very awkward to retrofit once accounts exist. It is also worth testing adversarially, by attempting to reach one customer's records through another's configuration.
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.
