What changes when it is travel & tourism

A webhook without signature verification is an open endpoint. Retries without exponential backoff are a denial-of-service attack on your own partners.

In travel & tourism, travellers need answers instantly, in their language, at any hour. That single fact reshapes how api design & integration has to be built here, the guardrails, the approval points and the evidence trail are design inputs rather than things bolted on before go-live.

The workload we are most often asked to take on first is booking and modification handling, usually integrated against GDS. We build the smallest thing that proves the case, put it in front of real users, and expand only what earns its keep.

Multi-model by default, so a provider outage is a routing decision rather than an incident. Six weeks to something running in production, not six quarters to a strategy document.

Questions from this sector

Can it handle booking changes?

Yes, with integration into your booking systems and clear approval limits on anything with a financial consequence.

What about disruptions?

Proactive notification and rebooking options are the highest-value automation in travel. It is precisely when volume spikes and human capacity does not.

REST or GraphQL?

REST for partner-facing and public APIs where caching and simplicity matter; GraphQL where a first-party client needs flexible, varied queries. Most systems end up with both, used deliberately.

Do you document it?

Generated from the OpenAPI specification, with a working sandbox. Documentation written by hand and separately always drifts.

Can you integrate with legacy SOAP systems?

Yes, usually by wrapping them in a clean modern interface rather than exposing the legacy contract onward.
