Give your customers compliance, without building it yourself
Best Guest's private partner API lets PMSs, channel managers, and booking engines offer guest registration and local authority reporting as a built-in feature — instead of sending customers to a separate tool, or building and maintaining country-specific compliance rails yourselves.
One API, many countries
A single integration point; country-specific reporting logic is handled behind the API.
Webhooks for real-time status (planned)
On our near-term roadmap — poll the API for status today.
Sandbox environment
Test your integration end-to-end before going live with real partners.
White-label ready
Present the check-in and registration flow as a native part of your product.
Built for scale
Designed for platforms serving hundreds or thousands of properties, not a single account.
EU-hosted data
Guest data is processed in line with GDPR and hosted in the EU.
What the API covers today
Reservation, check-in, and compliance endpoints are available to integration partners we onboard directly. Automated local authority filing exists today for Czechia (UbyPort); other countries are covered with ready-to-file documents while their official systems are integrated.
